Chapter 1 IntroductionNWA5000 / WAC6500 Series User’s Guide12You can set the NWA/WAC to operate in either standalone AP or managed AP mode. When the NWA/WAC is in standalone AP mode, it can serve as a normal AP, as an RF monitor to search for rouge APs to help eliminate network threats (if it supports monitor mode and rogue APs detection), or even as a root AP or a wireless repeater to establish wireless links with other APs in a WDS (Wireless Distribution System). A WDS is a wireless connection between two or more APs.Your NWA/WAC’s business-class reliability, SMB features, and centralized wireless management make it ideally suited for advanced service delivery in mission-critical networks. It uses Multiple BSSID and VLAN to provide simultaneous independent virtual APs. Additionally, innovations in roaming technology and QoS features eliminate voice call disruptions. The NWA/WAC controls network access with Media Access Control (MAC) address filtering, and rogue Access Point (AP) detection. It also provides a high level of network traffic security, supporting IEEE 802.1x, Wi-Fi Protected Access 2 and Wired Equivalent Privacy (WEP) data encryption.Your NWA/WAC is easy to install, configure and use. The embedded Web-based configurator enables simple, straightforward management and maintenance. See the Quick Start Guide for how to make hardware connections.1.1.1  Management Mode The NWA/WAC is a unified AP and can work either in standalone AP mode or in managed AP mode. If the NWA/WAC and a ZyXEL AP controller, such as the NXC2500 or NXC5500, are in the same subnet, it will be managed by the controller automatically.An AP controller uses Control And Provisioning of Wireless Access Points (CAPWAP, see RFC 5415) to discover and configure multiple managed APs.To set the NWA/WAC to be managed by an AP controller in a different subnet or change between management modes, use the AC (AP Controller) D iscovery screen (see Section 5.4 on page 63). When the NWA/WAC is in standalone AP mode and connects to a DHCP server, it uses the IP address assigned by the DHCP server. Otherwise, the NWA/WAC uses the default static management IP address (192.168.1.2). You can use the AC Discover y screen to have the NWA/WAC work as a managed AP.Number of Wireless Radios 2 2 2 2Monitor Mode & Rogue APs Detection Yes Yes Yes YesLayer-2 Isolation Yes Yes Yes YesExternal Antennas Yes No No YesInternal Antenna No Yes Yes NoMaximum number of log messages  512 event logs or 1024 debug logsTable 2   WAC Series Comparison TableFEATURES WAC6502D-E WAC6502D-S WAC6503D-S WAC6553D-ETable 3   NWA/WAC Management Mode ComparisonMANAGEMENT MODE DEFAULT IP ADDRESS UPLOAD FIRMWARE VIAStandalone APDynamic orStatic (192.168.1.2) Web Configurator or FTPManaged AP Dynamic CAPWAP or FTP
 Chapter 1 IntroductionNWA5000 / WAC6500 Series User’s Guide13When the NWA/WAC is in managed AP mode, it acts as a DHCP client and obtains an IP address from the AP controller. It can be configured ONLY by the AP controller. To change the NWA/WAC back to standalone AP mode, use the Reset  button to restore the default configuration. Alternatively, you need to check the AP controller for the NWA/WAC’s IP address and use FTP to upload the default configuration file at conf/system-default.conf to the NWA/WAC and reboot the device.1.1.2  MBSSIDA Basic Service Set (BSS) is the set of devices forming a single wireless network (usually an access point and one or more wireless clients). The Service Set IDentifier (SSID) is the name of a BSS. In Multiple BSS (MBSSID) mode, the NWA/WAC provides multiple virtual APs, each forming its own BSS and using its own individual SSID profile.You can configure multiple SSID profiles, and have all of them active at any one time.You can assign different wireless and security settings to each SSID profile. This allows you to compartmentalize groups of users, set varying access privileges, and prioritize network traffic to and from certain BSSs.To the wireless clients in the network, each SSID appears to be a different access point. As in any wireless network, clients can associate only with the SSIDs for which they have the correct security settings.For example, you might want to set up a wireless network in your office where Internet telephony (VoIP) users have priority. You also want a regular wireless network for standard users, as well as a ‘guest’ wireless network for visitors. In the following figure, V oI P_ SSI D users have QoS priority, SSI D 0 1  is the wireless network for standard users, and Gue st _ SSI D is the wireless network for guest users. In this example, the guest user is forbidden access to the wired Land Area Network (LAN) behind the AP and can access only the Internet.
Chapter 1 IntroductionNWA5000 / WAC6500 Series User’s Guide14Figure 1   Multiple BSSs1.1.3  Dual-RadioSome of the NWA/WAC models are equipped with dual wireless radios. This means you can configure two different wireless networks to operate simultaneously.Note: A different channel should be configured for each WLAN interface to reduce the effects of radio interference.You could use the 2.4 GHz band for regular Internet surfing and downloading while using the 5 GHz band for time sensitive traffic like high-definition video, music, and gaming.
 Chapter 1 IntroductionNWA5000 / WAC6500 Series User’s Guide15Figure 2   Dual-Radio Application 1.1.4  Root APIn Root AP mode, the NWA/WAC (Z) can act as the root AP in a wireless network and also allow repeaters (X and Y) to extend the range of its wireless network at the same time. In the figure below, both clients A, B and C can access the wired network through the root AP.Figure 3   Root AP Application On the NWA/WAC in Root AP mode, you can have multiple SSIDs active for regular wireless connections and one SSID for the connection with a repeater (repeater SSID). Wireless clients can
Chapter 1 IntroductionNWA5000 / WAC6500 Series User’s Guide16use either SSID to associate with the NWA/WAC in Root AP mode. A repeater must use the repeater SSID to connect to the NWA/WAC in Root AP mode.When the NWA/WAC is in Root AP mode, repeater security between the NWA/WAC and other repeater is independent of the security between the wireless clients and the AP or repeater. When repeater security is enabled, both APs and repeaters must use the same pre-shared key. See Section 6.2 on page 66 and Section 10.2 on page 106 for more details.Unless specified, the term “security settings” refers to the traffic between the wireless clients and the AP. At the time of writing, repeater security is compatible with the NWA/WAC only. 1.1.5  RepeaterThe NWA/WAC can act as a wireless network repeater to extend a root AP’s wireless network range, and also establish wireless connections with wireless clients. Using Repeater mode, your NWA/WAC can extend the range of the WLAN. In the figure below, the NWA/WAC in Repeater mode (Z) has a wireless connection to the NWA/WAC in Root AP mode (X) which is connected to a wired network and also has a wireless connection to another NWA/WAC in Repeater mode (Y) at the same time. Z and Y act as repeaters that forward traffic between associated wireless clients and the wired LAN. Clients A and B access the AP and the wired network behind the AP through repeaters Z and Y.Figure 4   Repeater ApplicationWhen the NWA/WAC is in Repeater mode, repeater security between the NWA/WAC and other repeater is independent of the security between the wireless clients and the AP or repeater. When repeater security is enabled, both APs and repeaters must use the same pre-shared key. See Section 6.2 on page 66 and Section 10.2 on page 106 for more details. Once the security settings of peer sides match one another, the connection between devices is made.
 Chapter 1 IntroductionNWA5000 / WAC6500 Series User’s Guide17At the time of writing, repeater security is compatible with the NWA/WAC only. 1.2  Ways to Manage the NWA/WACYou can use the following ways to manage the NWA/WAC.Web ConfiguratorThe Web Configurator allows easy NWA/WAC setup and management using an Internet browser. This User’s Guide provides information about the Web Configurator.Command-Line Interface (CLI)The CLI allows you to use text-based commands to configure the NWA/WAC. You can access it using remote management (for example, SSH or Telnet). See the Command Reference Guide for more information.File Transfer Protocol (FTP)This protocol can be used for firmware upgrades and configuration backup and restore.Simple Network Management Protocol (SNMP)The NWA/WAC can be monitored by an SNMP manager. See the SNMP chapter in this User’s Guide.1.3  Good Habits for Managing the NWA/WACDo the following things regularly to make the NWA/WAC more secure and to manage it more effectively.• Change the password often. Use a password that’s not easy to guess and that consists of different types of characters, such as numbers and letters.• Write down the password and put it in a safe place.• Back up the configuration (and make sure you know how to restore it). Restoring an earlier working configuration may be useful if the device becomes unstable or even crashes. If you forget your password, you will have to reset the NWA/WAC to its factory default settings. If you backed up an earlier configuration file, you won’t have to totally re-configure the NWA/WAC; you can simply restore your last configuration.1.4  Hardware ConnectionsSee your Quick Start Guide for information on making hardware connections.

NWA5000 / WAC6500 Series User’s Guide57CHAPTER   5Network5.1  OverviewThis chapter describes how you can configure the management IP address and VLAN settings of your NWA/WAC.The Internet Protocol (IP) address identifies a device on a network. Every networking device (including computers, servers, routers, printers, etc.) needs an IP address to communicate across the network. These networking devices are also known as hosts.Figure 28   IP SetupThe figure above illustrates one possible setup of your NWA/WAC. The gateway IP address is 192.168.1.1 and the managed IP address of the NWA/WAC is 192.168.1.2 (default), but if the NWA/WAC is assigned an IP address by a DHCP server, the default (192.168.1.2) will not be used. The gateway and the NWA/WAC must belong in the same IP subnet to be able to communicate with each other.5.1.1  Management ModeThis discusses using the NWA/WAC in management mode, which determines whether the NWA/WAC is used in its standalone mode, or as part of a Control And Provisioning of Wireless Access Points (CAPWAP) network. About CAPWAPThe NWA/WAC supports CAPWAP. This is ZyXEL’s implementation of the CAPWAP protocol (RFC 5415). The CAPWAP dataflow is protected by Datagram Transport Layer Security (DTLS).The following figure illustrates a CAPWAP wireless network. You (U) configure the AP controller (C), which then automatically updates the configurations of the managed APs (M1  ~ M 4 ).
Chapter 5 NetworkNWA5000 / WAC6500 Series User’s Guide58Figure 29   CAPWAP Network ExampleNote: The NWA/WAC can be a standalone AP (default), or a CAPWAP managed AP.CAPWAP Discovery and ManagementThe link between CAPWAP-enabled access points proceeds as follows:1An AP in managed AP mode joins a wired network (receives a dynamic IP address).2The AP sends out a discovery request, looking for a CAPWAP AP controller.3If there is an AP controller on the network, it receives the discovery request. If the AP controller is in Ma nua l mode it adds the details of the AP to its Unm a na ged Access Poin ts list, and you decide which available APs to manage. If the AP is in Alw a ys Accept  mode, it automatically adds the AP to its Ma nage d Access Points list and provides the managed AP with default configuration information, as well as securely transmitting the DTLS pre-shared key. The managed AP is ready for association with wireless clients.Managed AP Finds the ControllerA managed NWA/WAC can find the controller in one of the following ways:• Manually specify the controller’s IP address in the Web Configurator’s AC (AP Controller) Discover y screen. • Get the controller’s IP address from a DHCP server with the controller’s IP address configured as option 138.• Get the controller’s IP address from a DNS server SRV (Service) record.• Broadcasting to discover the controller within the broadcast domain.Note: The AP controller needs to have a static IP address. If it is a DHCP client, set the DHCP server to reserve an IP address for the AP controller.
 Chapter 5 NetworkNWA5000 / WAC6500 Series User’s Guide59CAPWAP and IP SubnetsBy default, CAPWAP works only between devices with IP addresses in the same subnet. However, you can configure CAPWAP to operate between devices with IP addresses in different subnets by doing the following.• Activate DHCP. Your network’s DHCP server must support option 138 defined in RFC 5415.• Configure DHCP option 138 with the IP address of the CAPWAP AP controller on your network.DHCP Option 138 allows the CAPWAP management request (from the AP in managed AP mode) to reach the AP controller in a different subnet, as shown in the following figure.Figure 30   CAPWAP and DHCP Option 138 Notes on CAPWAPThis section lists some additional features of ZyXEL’s implementation of the CAPWAP protocol.• When the AP controller uses its internal Remote Authentication Dial In User Service (RADIUS) server, managed APs also use the AP controller’s authentication server to authenticate wireless clients.• If a managed AP’s link to the AP controller is broken, the managed AP continues to use the wireless settings with which it was last provided.5.1.2  What You Can Do in this Chapter•The I P Set ting screen (Section 5.2 on page 60) configures the NWA/WAC’s LAN IP address. •The VLAN  screen (Section 5.3 on page 61) configures the NWA/WAC’s VLAN settings. •The AC (AP Controller) Discover y screen (Section 5.3 on page 61) configures the NWA/WAC’s AP Controller settings.

Chapter 5 NetworkNWA5000 / WAC6500 Series User’s Guide62In the figure above, to access and manage the NWA/WAC from computer A, the NWA/WAC and switch B’s ports to which computer A and the NWA/WAC are connected should be in the same VLAN.A Virtual Local Area Network (VLAN) allows a physical network to be partitioned into multiple logical networks. Devices on a logical network belong to one group. A device can belong to more than one group. With VLAN, a device cannot directly talk to or hear from devices that are not in the same group(s); the traffic must first go through a router.VLAN also increases network performance by limiting broadcasts to a smaller and more manageable logical broadcast domain. In traditional switched environments, all broadcast packets go to each and every individual port. With VLAN, all broadcasts are confined to a specific broadcast domain. IEEE 802.1Q TagThe IEEE 802.1Q standard defines an explicit VLAN tag in the MAC header to identify the VLAN membership of a frame across bridges. A VLAN tag includes the 12-bit VLAN ID and 3-bit user priority. The VLAN ID associates a frame with a specific VLAN and provides the information that devices need to process the frame across the network. Use this screen to configure the VLAN settings for your NWA/WAC.

NWA5000 / WAC6500 Series User’s Guide65CHAPTER   6Wireless6.1  OverviewThis chapter discusses how to configure the wireless network settings in your NWA/WAC. The following figure provides an example of a wireless network.Figure 35   Example of a Wireless NetworkThe wireless network is the part in the blue circle. In this wireless network, devices A and B are called wireless clients. The wireless clients use the access point (AP) to interact with other devices (such as the printer) or with the Internet. Your NWA/WAC is the AP.6.1.1  What You Can Do in this Chapter•The AP M ana gem en t screen (Section 6.2 on page 66) manages the NWA/WAC’s general wireless settings.•The MON Mode screen (Section 6.3 on page 69) allows you to assign APs either to the rogue AP list or the friendly AP list.•The Load Balancing screen (Section 6.4 on page 71) configures network traffic load balancing between the APs and the NWA/WAC. •The DCS screen (Section 6.5 on page 74) configures dynamic radio channel selection.

Chapter 6 WirelessNWA5000 / WAC6500 Series User’s Guide72Each field is described in the following table.  6.4.1  Disassociating and Delaying ConnectionsWhen your AP becomes overloaded, there are two basic responses it can take. The first one is to “delay” a client connection. This means that the AP withholds the connection until the data transfer throughput is lowered or the client connection is picked up by another AP. If the client is picked up by another AP then the original AP cannot resume the connection.Table 35   Configuration > Wireless > Load BalancingLABEL  DESCRIPTIONEnable Load BalancingSelect this to enable load balancing on the NWA/WAC.Use this section to configure wireless network traffic load balancing between the managd APs in this group.Mode Select a mode by which load balancing is carried out.Select By St a tion N um ber to balance network traffic based on the number of specified stations connected to the NWA/WAC.Select By Traffic Level to balance network traffic based on the volume generated by the stations connected to the NWA/WAC.Select By Sm a rt Classr oom  to balance network traffic based on the number of specified stations connected to the NWA/WAC. The NWA/WAC ignores association request and authentication request packets from any new station when the maximum number of stations is reached.If you select By Sta t ion N um ber or By Tr affic Level, once the threshold is crossed (either the maximum station numbers or with network traffic), the NWA/WAC delays association request and authentication request packets from any new station that attempts to make a connection. This allows the station to automatically attempt to connect to another, less burdened AP if one is available.Max Station Number Enter the threshold number of stations at which the NWA/WAC begins load balancing its connections.Traffic Level Select the threshold traffic level at which the NWA/WAC begins load balancing its connections (Low , Medium , High).Disassociate station when overloadedThis function is enabled by default and the disassociation priority is always Signal St r e ngt h when you set Mode to By Sm art  Classroom .Select this option to disassociate wireless clients connected to the AP when it becomes overloaded. If you do not enable this option, then the AP simply delays the connection until it can afford the bandwidth it requires, or it transfers the connection to another AP within its broadcast radius.The disassociation priority is determined automatically by the NWA/WAC and is as follows:•I dle Tim e out - Devices that have been idle the longest will be kicked first. If none of the connected devices are idle, then the priority shifts to Signal St rength.•Signal Str e n gt h - Devices with the weakest signal strength will be kicked first.Note: If you enable this function, you should ensure that there are multiple APs within the broadcast radius that can accept any rejected or kicked wireless clients; otherwise, a wireless client attempting to connect to an overloaded AP will be disassociated permanently and never be allowed to connect.Apply Click Apply to save your changes back to the NWA/WAC.Reset Click Re se t  to return the screen to its last-saved settings.
 Chapter 6 WirelessNWA5000 / WAC6500 Series User’s Guide73For example, here the AP has a balanced bandwidth allotment of 6 Mbps. If laptop R connects and it pushes the AP over its allotment, say to 7 Mbps, then the AP delays the red laptop’s connection until it can afford the bandwidth or the laptop is picked up by a different AP with bandwidth to spare.Figure 40   Delaying a ConnectionThe second response your AP can take is to kick the connections that are pushing it over its balanced bandwidth allotment.Figure 41   Kicking a ConnectionConnections are kicked based on either idle tim eout  or signal st ren gth . The NWA/WAC first looks to see which devices have been idle the longest, then starts kicking them in order of highest idle time. If no connections are idle, the next criteria the NWA/WAC analyzes is signal strength. Devices with the weakest signal strength are kicked first.

Click Configur at ion >  W ir eless >  DCS to access this screen.Figure 42   Configuration > Wireless > DCS      Each field is described in the following table.  6.6  Technical ReferenceThe following section contains additional technical information about the features described in this chapter.Dynamic Channel SelectionWhen numerous APs broadcast within a given area, they introduce the possibility of heightened radio interference, especially if some or all of them are broadcasting on the same radio channel. If the interference becomes too great, then the network administrator must open his AP configuration options and manually change the channel to one that no other AP is using (or at least a channel that has a lower level of interference) in order to give the connected stations a minimum degree of interference. Dynamic channel selection frees the network administrator from this task by letting the AP do it automatically. The AP can scan the area around it looking for the channel with the least amount of interference.In the 2.4 GHz spectrum, each channel from 1 to 13 is broken up into discrete 22 MHz segments that are spaced 5 MHz apart. Channel 1 is centered on 2.412 GHz while channel 13 is centered on 2.472 GHz.Table 36   Configuration > Wireless > DCSLABEL  DESCRIPTIONSelect Now Click this to have the NWA/WAC scan for and select an available channel immediately.Apply Click Apply to save your changes back to the NWA/WAC.Reset Click Re se t  to return the screen to its last-saved settings.
 Chapter 6 WirelessNWA5000 / WAC6500 Series User’s Guide75Figure 43   An Example Three-Channel DeploymentThree channels are situated in such a way as to create almost no interference with one another if used exclusively: 1, 6 and 11. When an AP broadcasts on any of these three channels, it should not interfere with neighboring APs as long as they are also limited to same trio.Figure 44   An Example Four-Channel DeploymentHowever, some regions require the use of other channels and often use a safety scheme with the following four channels: 1, 4, 7 and 11. While they are situated sufficiently close to both each other and the three so-called “safe” channels (1,6 and 11) that interference becomes inevitable, the severity of it is dependent upon other factors: proximity to the affected AP, signal strength, activity, and so on.Finally, there is an alternative four channel scheme for ETSI, consisting of channels 1, 5, 9, 13. This offers significantly less overlap that the other one.Figure 45   An Alternative Four-Channel DeploymentLoad BalancingBecause there is a hard upper limit on an AP’s wireless bandwidth, load balancing can be crucial in areas crowded with wireless users. Rather than let every user connect and subsequently dilute the available bandwidth to the point where each connecting device receives a meager trickle, the load balanced AP instead limits the incoming connections as a means to maintain bandwidth integrity.
Chapter 6 WirelessNWA5000 / WAC6500 Series User’s Guide76There are two kinds of wireless load balancing available on the NWA/WAC: Loa d balancin g by st a tion  nu m ber limits the number of devices allowed to connect to your AP. If you know exactly how many stations you want to let connect, choose this option.For example, if your company’s graphic design team has their own AP and they have 10 computers, you can load balance for 10. Later, if someone from the sales department visits the graphic design team’s offices for a meeting and he tries to access the network, his computer’s connection is delayed, giving it the opportunity to connect to a different, neighboring AP. If he still connects to the AP regardless of the delay, then the AP may boot other people who are already connected in order to associate with the new connection.Loa d balancin g by tra ffic le vel limits the number of connections to the AP based on maximum bandwidth available. If you are uncertain as to the exact number of wireless connections you will have then choose this option. By setting a maximum bandwidth cap, you allow any number of devices to connect as long as their total bandwidth usage does not exceed the configured bandwidth cap associated with this setting. Once the cap is hit, any new connections are rejected or delayed provided that there are other APs in range.Imagine a coffee shop in a crowded business district that offers free wireless connectivity to its customers. The coffee shop owner can’t possibly know how many connections his AP will have at any given moment. As such, he decides to put a limit on the bandwidth that is available to his customers but not on the actual number of connections he allows. This means anyone can connect to his wireless network as long as the AP has the bandwidth to spare. If too many people connect and the AP hits its bandwidth cap then all new connections must basically wait for their turn or get shunted to the nearest identical AP.

NWA5000 / WAC6500 Series User’s Guide84CHAPTER   8AP Profile8.1  OverviewThis chapter shows you how to configure preset profiles for the NWA/WAC. 8.1.1  What You Can Do in this Chapter•The Ra dio screen (Section 8.2 on page 85) creates radio configurations that can be used by the APs.•The SSI D  screen (Section 8.3 on page 89) configures three different types of profiles for your networked APs.8.1.2  What You Need To KnowThe following terms and concepts may help as you read this chapter.Wireless ProfilesAt the heart of all wireless AP configurations on the NWA/WAC are profiles. A profile represents a group of saved settings that you can use across any number of connected APs. You can set up the following wireless profile types:•Ra dio - This profile type defines the properties of an AP’s radio transmitter. You can have a maximum of 32 radio profiles on the NWA/WAC.•SSI D  - This profile type defines the properties of a single wireless network signal broadcast by an AP. Each radio on a single AP can broadcast up to 8 SSIDs. You can have a maximum of 32 SSID profiles on the NWA/WAC.•Se cu r it y  - This profile type defines the security settings used by a single SSID. It controls the encryption method required for a wireless client to associate itself with the SSID. You can have a maximum of 32 security profiles on the NWA/WAC.•MAC Filt er ing - This profile provides an additional layer of security for an SSID, allowing you to block access or allow access to that SSID based on wireless client MAC addresses. If a client’s MAC address is on the list, then it is either allowed or denied, depending on how you set up the MAC Filter profile. You can have a maximum of 32 MAC filtering profiles on the NWA/WAC.•La yer - 2  I sola tion - This profile defines the MAC addresses of the devices that you want to allow the associated wireless clients to have access to when layer-2 isolation is enabled. SSIDThe SSID (Service Set IDentifier) is the name that identifies the Service Set with which a wireless station is associated. Wireless stations associating to the access point (AP) must have the same SSID. In other words, it is the name of the wireless network that clients use to connect to it.
 Chapter 8 AP ProfileNWA5000 / WAC6500 Series User’s Guide85WEPWEP (Wired Equivalent Privacy) encryption scrambles all data packets transmitted between the AP and the wireless stations associated with it in order to keep network communications private. Both the wireless stations and the access points must use the same WEP key for data encryption and decryption.WPA2WPA2 (IEEE 802.11i) is a wireless security standard that defines stronger encryption, authentication and key management than WPA. Key differences between WPA2 and WEP are improved data encryption and user authentication.IEEE 802.1x The IEEE 802.1x standard outlines enhanced security methods for both the authentication of wireless stations and encryption key management. Authentication is done using an external RADIUS server. 8.2  RadioThis screen allows you to create radio profiles for the NWA/WAC.

The transmission rate of your NWA/WAC might be reduced.•ac: allows IEEE 802.11ac compliant WLAN devices to associate with the WAC. Channel Width Select the channel bandwidth you want to use for your wireless network.Select 2 0  M Hz if you want to lessen radio interference with other wireless devices in your neighborhood.Select 2 0 / 4 0  MHz to allow the NWA/WAC to choose the channel bandwidth (20 or 40 MHz) that has least interference.Select 2 0 / 4 0 / 8 0  MHz to allow the NWA/WAC to choose the channel bandwidth (20 or 40 or 80 MHz) that has least interference.Channel Selection This is the radio channel which the signal will use for broadcasting by this radio profile.•DCS: Choose Dynamic Channel Selection to have the NWA/WAC choose a radio channel that has least interference.•Ma nua l: Choose from the available radio channels in the list. If your NWA/WAC is outdoor type, be sure to choose non-indoors channels.DCS Time Interval Enter a number of minutes. This regulates how often the NWA/WAC surveys the other APs within its broadcast radius. If the channel on which it is currently broadcasting suddenly comes into use by another AP, the NWA/WAC will then dynamically select the next available clean channel or a channel with lower interference.Enable DCS Client Aware Select this to have the AP wait until all connected clients have disconnected before switching channels.If you disable this then the AP switches channels immediately regardless of any client connections. In this instance, clients that are connected to the AP when it switches channels are dropped.
Chapter 8 AP ProfileNWA5000 / WAC6500 Series User’s Guide882.4 GHz Channel Selection Method Select how you want to specify the channels the NWA/WAC switches between for 2.4 GHz operation. This field appears only when you choose 802.11b/g/n mode.Select a ut o to have the NWA/WAC display a 2 .4  GHz Ch a n n e l Deploym ent  field you can use to limit channel switching to 3 or 4 channels.Select m anual to select the individual channels the NWA/WAC switches between. Select channels from the Availa ble channels list and use the right arrow button to move them to the Channels sele ct e d list. 2.4 GHz Channel Deployment This is available when the 2 .4  GHz Cha nnel Se lect ion M e t hod is set to auto.Select Th r e e - Ch a nnel D e ploym ent  to limit channel switching to channels 1,6, and 11, the three channels that are sufficiently attenuated to have almost no impact on one another. In other words, this allows you to minimize channel interference by limiting channel-hopping to these three “safe” channels.Select Fou r - Ch a n nel Deploy m ent to limit channel switching to four channels. Depending on the country domain, if the only allowable channels are 1-11 then the NWA/WAC uses channels 1, 4, 7, 11 in this configuration; otherwise, the NWA/WAC uses channels 1, 5, 9, 13 in this configuration. Four channel deployment expands your pool of possible channels while keeping the channel interference to a minimum.Enable 5 GHz DFS Aware Select this if your APs are operating in an area known to have RADAR devices. This allows the devide to downgrade its frequency to below 5 GHz in the event RADAR signal is detected, thus preventing it from interfering with that signal.Enabling this forces the AP to select a non-DFS channel.5 GHz Channel Selection Method Select how you want to specify the channels the NWA/WAC switches between for 5 GHz operation.Select Au t o to have the NWA/WAC automatically select the best channel.Advanced SettingsGuard Interval Set the guard interval for this radio profile to either sh or t  or long. This option isn’t applicable if you choose 20 MHz channel width.The guard interval is the gap introduced between data transmission from users in order to reduce interference. Reducing the interval increases data transfer rates but also increases interference. Increasing the interval reduces data transfer rates but also reduces interference.Enable A-MPDU Aggregation Select this to enable A-MPDU aggregation.Message Protocol Data Unit (MPDU) aggregation collects Ethernet frames along with their 802.11n headers and wraps them in a 802.11n MAC header. This method is useful for increasing bandwidth throughput in environments that are prone to high error rates.Enable A-MSDU Aggregation Select this to enable A-MSDU aggregation.Mac Service Data Unit (MSDU) aggregation collects Ethernet frames without any of their 802.11n headers and wraps the header-less payload in a single 802.11n MAC header. This method is useful for increasing bandwidth throughput. It is also more efficient than A-MPDU except in environments that are prone to high error rates.RTS/CTS Threshold Use RTS/CTS to reduce data collisions on the wireless network if you have wireless clients that are associated with the same AP but out of range of one another. When enabled, a wireless client sends an RTS (Request To Send) and then waits for a CTS (Clear To Send) before it transmits. This stops wireless clients from transmitting packets at the same time (and causing data collisions). A wireless client sends an RTS for all packets larger than the number (of bytes) that you enter here. Set the RTS/CTS equal to or higher than the fragmentation threshold to turn RTS/CTS off.Table 43   Configuration > Object > AP Profile > Add/Edit Profile (continued)LABEL DESCRIPTION
 Chapter 8 AP ProfileNWA5000 / WAC6500 Series User’s Guide898.3  SSID The SSID screens allow you to configure three different types of profiles for your networked APs: an SSID list, which can assign specific SSID configurations to your APs; a security list, which can assign specific encryption methods to the APs when allowing wireless clients to connect to them; and a MAC filter list, which can limit connections to an AP based on wireless clients MAC addresses.Beacon Interval When a wirelessly networked device sends a beacon, it includes with it a beacon interval. This specifies the time period before the device sends the beacon again. The interval tells receiving devices on the network how long they can wait in low-power mode before waking up to handle the beacon. A high value helps save current consumption of the access point. DTIM Delivery Traffic Indication Message (DTIM) is the time period after which broadcast and multicast packets are transmitted to mobile clients in the Active Power Management mode. A high DTIM value can cause clients to lose connectivity with the network. This value can be set from 1 to 255.Enable Signal Threshold Select the check box to use the signal threshold to ensure wireless clients receive good throughput. This allows only wireless clients with a strong signal to connect to the AP.Clear the check box to not require wireless clients to have a minimum signal strength to connect to the AP.Station Signal Threshold Set a minimum client signal strength. A wireless client is allowed to connect to the AP only when its signal strength is stronger than the specified threshold. -20 dBm is the strongest signal you can require and -76 is the weakest.Disassociate Station ThresholdSet a minimum kick-off signal strength. When a wireless client’s signal strength is lower than the specified threshold, the NWA/WAC disconnects the wireless client from the AP. -20 dBm is the strongest signal you can require and -90 is the weakest.Allow Station Connection after Multiple RetriesSelect this option to allow a wireless client to try to associate with the AP again after it is disconnected due to weak signal strength.Station Retry Count Set the maximum number of times a wireless client can attempt to re-connect to the AP Multicast SettingsTransmission Mode Specify how the NWA/WAC handles wireless multicast traffic.Select M ult ica st  t o Un ica st to broadcast wireless multicast traffic to all of the wireless clients as unicast traffic. Unicast traffic dynamically changes the data rate based on the application’s bandwidth requirements. The retransmit mechanism of unicast traffic provides more reliable transmission of the multicast traffic, although it also produces duplicate packets.Select Fix e d M ult icast  Rate  to send multicast traffic to all wireless clients at a single data rate. You must know the multicast application’s bandwidth requirements and set it in the following field.Multicast Rate(Mbps) If you set Tr a n sm ission M ode to Fix e d M ultica st  Ra t e, select a data rate at which the NWA/WAC transmits multicast packets to wireless clients.

Access categories minimize the delay of data packets across a wireless network. Certain categories, such as video or voice, are given a higher priority due to the time sensitive nature of their data packets.QoS access categories are as follows:disable: Turns off QoS for this SSID. All data packets are treated equally and not tagged with access categories.W M M : Enables automatic tagging of data packets. The NWA/WAC assigns access categories to the SSID by examining data as it passes through it and making a best guess effort. If something looks like video traffic, for instance, it is tagged as such.W M M _ V OI CE: All wireless traffic to the SSID is tagged as voice data. This is recommended if an SSID is used for activities like placing and receiving VoIP phone calls.W M M _ V I D EO: All wireless traffic to the SSID is tagged as video data. This is recommended for activities like video conferencing.W M M _ BEST_ EFFO RT: All wireless traffic to the SSID is tagged as “best effort,” meaning the data travels the best route it can without displacing higher priority traffic. This is good for activities that do not require the best bandwidth throughput, such as surfing the Internet.W M M _ BACKGROU N D : All wireless traffic to the SSID is tagged as low priority or “background traffic”, meaning all other access categories take precedence over this one. If traffic from an SSID does not have strict throughput requirements, then this access category is recommended. For example, an SSID that only has network printers connected to it.VLAN ID Enter a VLAN ID for the NWA/WAC to use to tag traffic originating from this SSID.Hidden SSID Select this if you want to “hide” your SSID from wireless clients. This tells any wireless clients in the vicinity of the AP using this SSID profile not to display its SSID name as a potential connection. Not all wireless clients respect this flag and display it anyway.When a SSID is “hidden” and a wireless client cannot see it, the only way you can connect to the SSID is by manually entering the SSID name in your wireless connection setup screen(s) (these vary by client, client connectivity software, and operating system).Enable Intra-BSS Traffic BlockingSelect this option to prevent crossover traffic from within the same SSID.OK Click OK to save your changes back to the NWA/WAC.Cancel Click Cance l to exit this screen without saving your changes.Table 45   Configuration > Object > AP Profile > Add/Edit SSID Profile (continued)LABEL DESCRIPTION

Attackers can take advantage of a rogue AP’s weaker (or non-existent) security to gain access to the network, or set up their own rogue APs in order to capture information from wireless clients. If a scan reveals a rogue AP, you can use commercially-available software to physically locate it.Table 53   Configuration > Object > MON Profile > Add/Edit MON ProfileLABEL DESCRIPTIONActivate Select this to activate this monitor mode profile.Profile Name This field indicates the name assigned to the monitor mode profile.Channel dwell time Enter the interval (in milliseconds) before the NWA/WAC switches to another channel for monitoring.Scan Channel Mode Select a u t o to have the NWA/WAC switch to the next sequential channel once the Channel dw ell t im e expires.Select m anual to set specific channels through which to cycle sequentially when the Channel dw ell t im e expires.

The company’s legitimate wireless network (the dashed ellipse B) is well-secured, but the rogue AP uses inferior security that is easily broken by an attacker (X) running readily available encryption-cracking software. In this example, the attacker now has access to the company network, including sensitive data stored on the file server (C).Friendly APsIf you have more than one AP in your wireless network, you should also configure a list of “friendly” APs. Friendly APs are other wireless access points that are detected in your network, as well as any others that you know are not a threat (those from recognized networks, for example). It is recommended that you export (save) your list of friendly APs often, especially if you have a network with a large number of access points.RGAXBC

NWA5000 / WAC6500 Series User’s Guide108CHAPTER   11Certificates11.1  OverviewThe NWA/WAC can use certificates (also called digital IDs) to authenticate users. Certificates are based on public-private key pairs. A certificate contains the certificate owner’s identity and public key. Certificates provide a way to exchange public keys for use in authentication. 11.1.1  What You Can Do in this Chapter•The My Certifica te  screens (Section 11.2 on page 111) generate and export self-signed certificates or certification requests and import the NWA/WAC’s CA-signed certificates.•The Truste d Ce rt ificat es screens (Section 11.3 on page 119) save CA certificates and trusted remote host certificates to the NWA/WAC. The NWA/WAC trusts any valid certificate that you have imported as a trusted certificate. It also trusts any valid certificate signed by any of the certificates that you have imported as a trusted certificate. 11.1.2  What You Need to KnowThe following terms and concepts may help as you read this chapter.When using public-key cryptology for authentication, each host has two keys. One key is public and can be made openly available. The other key is private and must be kept secure. These keys work like a handwritten signature (in fact, certificates are often referred to as “digital signatures”). Only you can write your signature exactly as it should look. When people know what your signature looks like, they can verify whether something was signed by you, or by someone else. In the same way, your private key “writes” your digital signature and your public key allows people to verify whether data was signed by you, or by someone else. This process works as follows:1Tim wants to send a message to Jenny. He needs her to be sure that it comes from him, and that the message content has not been altered by anyone else along the way. Tim generates a public key pair (one public key and one private key). 2Tim keeps the private key and makes the public key openly available. This means that anyone who receives a message seeming to come from Tim can read it and verify whether it is really from him or not. 3Tim uses his private key to sign the message and sends it to Jenny.4Jenny receives the message and uses Tim’s public key to verify it. Jenny knows that the message is from Tim, and that although other people may have been able to read the message, no-one can have altered it (because they cannot re-sign the message with Tim’s private key).
 Chapter 11 CertificatesNWA5000 / WAC6500 Series User’s Guide1095Additionally, Jenny uses her own private key to sign a message and Tim uses Jenny’s public key to verify the message.The NWA/WAC uses certificates based on public-key cryptology to authenticate users attempting to establish a connection, not to encrypt the data that you send after establishing a connection. The method used to secure the data that you send through an established connection depends on the type of connection.The certification authority uses its private key to sign certificates. Anyone can then use the certification authority’s public key to verify the certificates.A certification path is the hierarchy of certification authority certificates that validate a certificate. The NWA/WAC does not trust a certificate if any certificate on its path has expired or been revoked. Certification authorities maintain directory servers with databases of valid and revoked certificates. A directory of certificates that have been revoked before the scheduled expiration is called a CRL (Certificate Revocation List). The NWA/WAC can check a peer’s certificate against a directory server’s list of revoked certificates. The framework of servers, software, procedures and policies that handles keys is called PKI (public-key infrastructure).Advantages of CertificatesCertificates offer the following benefits.• The NWA/WAC only has to store the certificates of the certification authorities that you decide to trust, no matter how many devices you need to authenticate. • Key distribution is simple and very secure since you can freely distribute public keys and you never need to transmit private keys.Self-signed CertificatesYou can have the NWA/WAC act as a certification authority and sign its own certificates.Factory Default CertificateThe NWA/WAC generates its own unique self-signed certificate when you first turn it on. This certificate is referred to in the GUI as the factory default certificate. Certificate File FormatsAny certificate that you want to import has to be in one of these file formats:• Binary X.509: This is an ITU-T recommendation that defines the formats for X.509 certificates.• PEM (Base-64) encoded X.509: This Privacy Enhanced Mail format uses lowercase letters, uppercase letters and numerals to convert a binary X.509 certificate into a printable form.• Binary PKCS#7: This is a standard that defines the general syntax for data (including digital signatures) that may be encrypted. A PKCS #7 file is used to transfer a public key certificate. The private key is not included. The NWA/WAC currently allows the importation of a PKS#7 file that contains a single certificate. • PEM (Base-64) encoded PKCS#7: This Privacy Enhanced Mail (PEM) format uses lowercase letters, uppercase letters and numerals to convert a binary PKCS#7 certificate into a printable form.
Chapter 11 CertificatesNWA5000 / WAC6500 Series User’s Guide110• Binary PKCS#12: This is a format for transferring public key and private key certificates.The private key in a PKCS #12 file is within a password-encrypted envelope. The file’s password is not connected to your certificate’s public or private passwords. Exporting a PKCS #12 file creates this and you must provide it to decrypt the contents when you import the file into the NWA/WAC. Note: Be careful not to convert a binary file to text during the transfer process. It is easy for this to occur since many programs use text files by default. 11.1.3  Verifying a CertificateBefore you import a trusted certificate into the NWA/WAC, you should verify that you have the correct certificate. You can do this using the certificate’s fingerprint. A certificate’s fingerprint is a message digest calculated using the MD5 or SHA1 algorithm. The following procedure describes how to check a certificate’s fingerprint to verify that you have the actual certificate. 1Browse to where you have the certificate saved on your computer. 2Make sure that the certificate has a “.cer” or “.crt” file name extension.3Double-click the certificate’s icon to open the Ce r t ifica t e  window. Click the D e t ail s tab and scroll down to the Th um bprint  Algorit hm  and Thu m b print  fields. 4Use a secure method to verify that the certificate owner has the same information in the Thum bprint  Algorith m  and Th u m b prin t  fields. The secure method may very based on your situation. Possible examples would be over the telephone or through an HTTPS connection.

You can use up to 31 alphanumeric and ;‘~!@#$%^&()_+[]{}’,.=- characters.Certification Path Click the Refresh button to have this read-only text box display the end entity’s certificate and a list of certification authority certificates that shows the hierarchy of certification authorities that validate the end entity’s certificate. If the issuing certification authority is one that you have imported as a trusted certificate, it may be the only certification authority in the list (along with the end entity’s own certificate). The NWA/WAC does not trust the end entity’s certificate and displays “Not trusted” in this field if any certificate on the path has expired or been revoked.Refresh Click Refresh to display the certification path.Enable X.509v3 CRL Distribution Points and OCSP checking Select this check box to have the NWA/WAC check incoming certificates that are signed by this certificate against a Certificate Revocation List (CRL) or an OCSP server. You also need to configure the OSCP or LDAP server details.OCSP Server Select this check box if the directory server uses OCSP (Online Certificate Status Protocol).URL Type the protocol, IP address and pathname of the OCSP server. ID The NWA/WAC may need to authenticate itself in order to assess the OCSP server. Type the login name (up to 31 ASCII characters) from the entity maintaining the server (usually a certification authority).Password Type the password (up to 31 ASCII characters) from the entity maintaining the OCSP server (usually a certification authority).LDAP Server Select this check box if the directory server uses LDAP (Lightweight Directory Access Protocol). LDAP is a protocol over TCP that specifies how clients access directories of certificates and lists of revoked certificates.Address Type the IP address (in dotted decimal notation) of the directory server. Port Use this field to specify the LDAP server port number. You must use the same server port number that the directory server uses. 389 is the default server port number for LDAP.ID The NWA/WAC may need to authenticate itself in order to assess the CRL directory server. Type the login name (up to 31 ASCII characters) from the entity maintaining the server (usually a certification authority).Password Type the password (up to 31 ASCII characters) from the entity maintaining the CRL directory server (usually a certification authority).Certificate InformationThese read-only fields display detailed information about the certificate. Type This field displays general information about the certificate. CA-signed means that a Certification Authority signed the certificate. Self-signed means that the certificate’s owner signed the certificate (not a certification authority).  X.509 means that this certificate was created and signed according to the ITU-T X.509 recommendation that defines the formats for public-key certificates.Version This field displays the X.509 version number. Serial Number This field displays the certificate’s identification number given by the certification authority.Subject This field displays information that identifies the owner of the certificate, such as Common Name (CN), Organizational Unit (OU), Organization (O) and Country (C).Issuer This field displays identifying information about the certificate’s issuing certification authority, such as Common Name, Organizational Unit, Organization and Country.

Follow the instructions in this screen to save a trusted certificate to the NWA/WAC.Note: You must remove any spaces from the certificate’s filename before you can import the certificate.Signature Algorithm This field displays the type of algorithm that was used to sign the certificate. Some certification authorities use rsa-pkcs1-sha1 (RSA public-private key encryption algorithm and the SHA1 hash algorithm). Other certification authorities may use rsa-pkcs1-md5 (RSA public-private key encryption algorithm and the MD5 hash algorithm).Valid From This field displays the date that the certificate becomes applicable. The text displays in red and includes a Not Yet Valid! message if the certificate has not yet become applicable.Valid To This field displays the date that the certificate expires. The text displays in red and includes an Expiring! or Expired! message if the certificate is about to expire or has already expired.Key Algorithm This field displays the type of algorithm that was used to generate the certificate’s key pair (the NWA/WAC uses RSA encryption) and the length of the key set in bits (1024 bits for example).Subject Alternative NameThis field displays the certificate’s owner‘s IP address (IP), domain name (DNS) or e-mail address (EMAIL).Key Usage This field displays for what functions the certificate’s key can be used. For example, “DigitalSignature” means that the key can be used to sign certificates and “KeyEncipherment” means that the key can be used to encrypt text.Basic Constraint This field displays general information about the certificate. For example, Subject Type=CA means that this is a certification authority’s certificate and   “Path Length Constraint=1” means that there can only be one certification authority in the certificate’s path.MD5 Fingerprint This is the certificate’s message digest that the NWA/WAC calculated using the MD5 algorithm. You can use this value to verify with the certification authority (over the phone for example) that this is actually their certificate. SHA1 Fingerprint This is the certificate’s message digest that the NWA/WAC calculated using the SHA1 algorithm. You can use this value to verify with the certification authority (over the phone for example) that this is actually their certificate.Certificate This read-only text box displays the certificate or certification request in Privacy Enhanced Mail (PEM) format. PEM uses lowercase letters, uppercase letters and numerals to convert a binary certificate into a printable form.You can copy and paste the certificate into an e-mail to send to friends or colleagues or you can copy and paste the certificate into a text editor and save the file on a management computer for later distribution (via floppy disk for example).Export Certificate Click this button and then Sa ve in the File Dow n load screen.

With OCSP the NWA/WAC checks the status of individual certificates instead of downloading a Certificate Revocation List (CRL). OCSP has two main advantages over a CRL. The first is real-time status information. The second is a reduction in network traffic since the NWA/WAC only gets information on the certificates that it needs to verify, not a huge list. When the NWA/WAC requests certificate status information, the OCSP server returns a “expired”, “current” or “unknown” response.Table 62   Configuration > Object > Certificate > Trusted Certificates > ImportLABEL DESCRIPTIONFile Path  Type in the location of the file you want to upload in this field or click Br ow se to find it.You cannot import a certificate with the same name as a certificate that is already in the NWA/WAC.Browse Click Brow se  to find the certificate file you want to upload.

Enable Daylight Saving Daylight saving is a period from late spring to fall when many countries set their clocks ahead of normal local time by one hour to give more daytime light in the evening.Select this option if you use Daylight Saving Time.Start Date Configure the day and time when Daylight Saving Time starts if you selected En a ble  Daylight  Sa ving. The at  field uses the 24 hour format. Here are a couple of examples:Daylight Saving Time starts in most parts of the United States on the second Sunday of March. Each time zone in the United States starts using Daylight Saving Time at 2 A.M. local time. So in the United States you would select Se con d, Sunda y, March  and type 2 in the a t  field.Daylight Saving Time starts in the European Union on the last Sunday of March. All of the time zones in the European Union start using Daylight Saving Time at the same moment (1 A.M. GMT or UTC). So in the European Union you would select La st , Sunday, March. The time you type in the at  field depends on your time zone. In Germany for instance, you would type 2 because Germany's time zone is one hour ahead of GMT or UTC (GMT+1).
Chapter 12 SystemNWA5000 / WAC6500 Series User’s Guide12812.3.1  Pre-defined NTP Time Servers ListWhen you turn on the NWA/WAC for the first time, the date and time start at 2003-01-01 00:00:00. The NWA/WAC then attempts to synchronize with one of the following pre-defined list of Network Time Protocol (NTP) time servers.The NWA/WAC continues to use the following pre-defined list of NTP time servers if you do not specify a time server or it cannot synchronize with the time server you specified. When the NWA/WAC uses the pre-defined list of NTP time servers, it randomly selects one server and tries to synchronize with it. If the synchronization fails, then the NWA/WAC goes through the rest of the list in order from the first one tried until either it is successful or all the pre-defined NTP time servers have been tried.12.3.2  Time Server SynchronizationClick the Sync.

HTTPS and SSH access are secure. HTTP, Telnet, and FTP management access are not secure.
Chapter 12 SystemNWA5000 / WAC6500 Series User’s Guide130Figure 76   Secure and Insecure Service Access From the WAN12.4.1  Service Access LimitationsA service cannot be used to access the NWA/WAC when you have disabled that service in the corresponding screen.12.4.2  System TimeoutThere is a lease timeout for administrators. The NWA/WAC automatically logs you out if the management session remains idle for longer than this timeout period. The management session does not time out when a statistics screen is polling. Each user is also forced to log in the NWA/WAC for authentication again when the reauthentication time expires. You can change the timeout settings in the User  screens.12.4.3  HTTPSYou can set the NWA/WAC to use HTTP or HTTPS (HTTPS adds security) for Web Configurator sessions. HTTPS (HyperText Transfer Protocol over Secure Socket Layer, or HTTP over SSL) is a web protocol that encrypts and decrypts web pages. Secure Socket Layer (SSL) is an application-level protocol that enables secure transactions of data by ensuring confidentiality (an unauthorized party cannot read the transferred data), authentication (one party can identify the other party) and data integrity (you know if data has been changed). It relies upon certificates, public keys, and private keys (see Chapter 11 on page 108 for more information).HTTPS on the NWA/WAC is used so that you can securely access the NWA/WAC using the Web Configurator. The SSL protocol specifies that the HTTPS server (the NWA/WAC) must always authenticate itself to the HTTPS client (the computer which requests the HTTPS connection with the NWA/WAC), whereas the HTTPS client only should authenticate itself when the HTTPS server requires it to do so (select Auth ent ica te  Clie nt  Cert ificat es in the W W W  screen). Aut hent icat e Client  Cert ificat es is optional and if selected means the HTTPS client must send the NWA/WAC a

The issuing certificate authority of the NWA/WAC's factory default certificate is the NWA/WAC itself since the certificate is a self-signed certificate.
 Chapter 12 SystemNWA5000 / WAC6500 Series User’s Guide135• For the browser to trust a self-signed certificate, import the self-signed certificate into your operating system as a trusted certificate. • To have the browser trust the certificates issued by a certificate authority, import the certificate authority’s certificate into your operating system as a trusted certificate. Refer to Appendix A on page 188 for details.12.4.5.4  Enrolling and Importing SSL Client CertificatesThe SSL client needs a certificate if Aut hent ica te  Client Cer tifica te s is selected on the NWA/WAC. You must have imported at least one trusted CA to the NWA/WAC in order for the Aut he nt ica te  Client  Cert ificat es to be active (see the Certificates chapter for details). Apply for a certificate from a Certification Authority (CA) that is trusted by the NWA/WAC (see the NWA/WAC’s Tr usted Cert ificat es Web Configurator screen).Figure 82   Trusted CertificatesThe CA sends you a package containing the CA’s trusted certificate(s), your personal certificate(s) and a password to install the personal certificate(s).

This screen displays even if you only have a single certificate as in the example.3You next see the Web Configurator login screen.12.5  SSH   You can use SSH (Secure SHell) to securely access the NWA/WAC’s command line interface. SSH is a secure communication protocol that combines authentication and data encryption to provide secure encrypted communication between two hosts over an unsecured network. In the following figure, computer B on the Internet uses SSH to securely connect to the NWA/WAC (A) for a management session.Figure 83   SSH Communication Over the WAN Example12.5.1  How SSH WorksThe following figure is an example of how a secure connection is established between two remote hosts using SSH v1.
 Chapter 12 SystemNWA5000 / WAC6500 Series User’s Guide141Figure 84   How SSH v1 Works Example1Host IdentificationThe SSH client sends a connection request to the SSH server. The server identifies itself with a host key. The client encrypts a randomly generated session key with the host key and server key and sends the result back to the server.The client automatically saves any new server public keys. In subsequent connections, the server public key is checked against the saved version on the client computer.2Encryption MethodOnce the identification is verified, both the client and server must agree on the type of encryption method to use.3Authentication and Data TransmissionAfter the identification is verified and data encryption activated, a secure tunnel is established between the client and the server. The client then sends its authentication information (user name and password) to the server to log in to the server.12.5.2  SSH Implementation on the NWA/WACYour NWA/WAC supports SSH versions 1 and 2 using RSA authentication and four encryption methods (AES, 3DES, Archfour, and Blowfish).

Chapter 12 SystemNWA5000 / WAC6500 Series User’s Guide146Figure 91   SNMP Management ModelAn SNMP managed network consists of two main types of component: agents and a manager. An agent is a management software module that resides in a managed device (the NWA/WAC). An agent translates the local management information from the managed device into a form compatible with SNMP. The manager is the console through which network administrators perform network management functions. It executes applications that control and monitor managed devices. The managed devices contain object variables/managed objects that define each piece of information to be collected about a device. Examples of variables include such as number of packets received, node port status etc. A Management Information Base (MIB) is a collection of managed objects. SNMP allows a manager and agents to communicate for the purpose of accessing these objects.SNMP itself is a simple request/response protocol based on the manager/agent model. The manager issues a request and the agent returns responses using the following protocol operations:• Get - Allows the manager to retrieve an object variable from the agent. • GetNext - Allows the manager to retrieve the next object variable from a table or list within an agent. In SNMPv1, when a manager wants to retrieve all elements of a table from an agent, it initiates a Get operation, followed by a series of GetNext operations. • Set - Allows the manager to set values for object variables within an agent. • Trap - Used by the agent to inform the manager of some events.12.8.1  Supported MIBsThe NWA/WAC supports MIB II that is defined in RFC-1213 and RFC-1215. The NWA/WAC also supports private MIBs (ZYXEL-ES-CAPWAP.MIB, ZYXEL-ES-COMMON.MIB, ZYXEL-ES-ZyXELAPMgmt.MIB, ZYXEL-ES-PROWLAN.MIB, ZYXEL-ES-RFMGMT.MIB, ZYXEL-ES-SMI.MIB, and
 Chapter 12 SystemNWA5000 / WAC6500 Series User’s Guide147ZYXEL-ES-WIRELESS.MIB) to collect information about CPU and memory usage and VPN total throughput. The focus of the MIBs is to let administrators collect statistical data and monitor status and performance. You can download the NWA/WAC’s MIBs from www.zyxel.com.12.8.2  SNMP TrapsThe NWA/WAC will send traps to the SNMP manager when any one of the following events occurs.12.8.3  Configuring SNMP To change your NWA/WAC’s SNMP settings, click Configur at ion >  Syst em  >  SN M P tab. The screen appears as shown. Use this screen to configure your SNMP settings. You can also configure user profiles that define allowed SNMPv3 access.Figure 92   Configuration > System > SNMPTable 70   SNMP TrapsOBJECT LABEL OBJECT ID DESCRIPTIONlinkDown 1.3.6.1.6.3.1.1.5.3 This trap is sent when the Ethernet link is down.linkUp 1.3.6.1.6.3.1.1.5.4 This trap is sent when the Ethernet link is up.authenticationFailure 1.3.6.1.6.3.1.1.5.5 This trap is sent when an SNMP request comes from non-authenticated hosts.

NWA5000 / WAC6500 Series User’s Guide162CHAPTER   14File Manager14.1  OverviewConfiguration files define the NWA/WAC’s settings. Shell scripts are files of commands that you can store on the NWA/WAC and run when you need them. You can apply a configuration file or run a shell script without the NWA/WAC restarting. You can store multiple configuration files and shell script files on the NWA/WAC. You can edit configuration files or shell scripts in a text editor and upload them to the NWA/WAC. Configuration files use a .conf extension and shell scripts use a .zysh extension.14.1.1  What You Can Do in this Chapter•The Configura tion File  screen (Section 14.2 on page 163) stores and names configuration files. You can also download and upload configuration files.•The Firm w a re  Pack age screen (Section 14.3 on page 168) checks your current firmware version and uploads firmware to the NWA/WAC.•The Shell Script screen (Section 14.4 on page 170) stores, names, downloads, uploads and runs shell script files. 14.1.2  What you Need to KnowThe following terms and concepts may help as you read this chapter.Configuration Files and Shell ScriptsWhen you apply a configuration file, the NWA/WAC uses the factory default settings for any features that the configuration file does not include. When you run a shell script, the NWA/WAC only applies the commands that it contains. Other settings do not change. These files have the same syntax, which is also identical to the way you run CLI commands manually. An example is shown below# enter configuration modeconfigure terminal# change administrator passwordusername admin password 4321 user-type admin#configure default radio profile, change 2GHz channel to 11 & Tx output power # to 50%wlan-radio-profile default2g-channel 11output-power 50%exitwrite
 Chapter 14 File ManagerNWA5000 / WAC6500 Series User’s Guide163While configuration files and shell scripts have the same syntax, the NWA/WAC applies configuration files differently than it runs shell scripts. This is explained below.You have to run the aforementioned example as a shell script because the first command is run in Pr iv ilege mode. If you remove the first command, you have to run the example as a configuration file because the rest of the commands are executed in Con fig ura t ion mode.Comments in Configuration Files or Shell ScriptsIn a configuration file or shell script, use “#” or “!” as the first character of a command line to have the NWA/WAC treat the line as a comment. Your configuration files or shell scripts can use “exit” or a command line consisting of a single “!” to have the NWA/WAC exit sub command mode.Note: “exit” or “!'” must follow sub commands if it is to make the NWA/WAC exit sub command mode.In the following example lines 1 and 2 are comments. Line 5 exits sub command mode. ! this is from Joe# on 2010/12/05wlan-ssid-profile defaultssid Joe-APqos wmmsecurity default!Errors in Configuration Files or Shell ScriptsWhen you apply a configuration file or run a shell script, the NWA/WAC processes the file line-by-line. The NWA/WAC checks the first line and applies the line if no errors are detected. Then it continues with the next line. If the NWA/WAC finds an error, it stops applying the configuration file or shell script and generates a log. You can change the way a configuration file or shell script is applied. Include setenv stop-on-error off in the configuration file or shell script. The NWA/WAC ignores any errors in the configuration file or shell script and applies all of the valid commands. The NWA/WAC still generates a log for any errors. 14.2  Configuration FileClick M ainte nan ce  >  File Man ager  >  Configura tion  File to open this screen.

The backup configuration file will be useful in case you need to return to your previous settings. Configuration File Flow at Restart• If there is not a st ar t up- config.conf when you restart the NWA/WAC (whether through a management interface or by physically turning the power off and back on), the NWA/WAC uses the sy st e m - d efa ult . conf configuration file with the NWA/WAC’s default settings.•If there is a st a r t up- config .co nf, the NWA/WAC checks it for errors and applies it. If there are no errors, the NWA/WAC uses it and copies it to the la st g ood.con f configuration file as a back up file. If there is an error, the NWA/WAC generates a log and copies the st a rt up- config.con f configuration file to the st a r t up- config - ba d.con f configuration file and tries the existing la st g ood.conf configuration file. If there isn’t a last g ood.con f configuration file or it also has an error, the NWA/WAC applies the sy st e m - d efa ult . conf configuration file.• You can change the way the st a rt up- config .conf  file is applied. Include the setenv-startup stop-on-error off command. The NWA/WAC ignores any errors in the st a r t u p- config .conf file and applies all of the valid commands. The NWA/WAC still generates a log for any errors. Figure 99   Maintenance > File Manager > Configuration File Do not turn off the NWA/WAC while configuration file upload is in progress.

The deafult LED suppression setting of your AP is different depending on your NWA/WAC model. You can go to M a in t ena nce  > LED s > Suppre ssion screen to see the default of the LED behavior. If the Suppre ssion On check box is checked, it means the LEDs of your NWA/WAC will tur n off after it’s ready. On the other hand, if the check box is unchecked, it means the LEDs will st a y lit after the AP is ready. You can change the LED suppression setting in the M ain t e na nce  > LED s > Suppression screen. After you make changes in the suppression screen, it will be stored as the default when the NWA/WAC is restarted.

The file’s password is not connected to your certificate’s public or private passwords. Exporting a PKCS #12 file creates this and you must provide it to decrypt the contents when you import the file into the NWA/WAC. Note: Be careful not to convert a binary file to text during the transfer process. It is easy for this to occur since many programs use text files by default. I can only see newer logs. Older logs are missing. When a log reaches the maximum number of log messages, new log messages automatically  overwrite existing log messages, starting with the oldest existing log message first.The commands in my configuration file or shell script are not working properly.• In a configuration file or shell script, use “#” or “!” as the first character of a command line to have the NWA/WAC treat the line as a comment. • Your configuration files or shell scripts can use “exit” or a command line consisting of a single “!” to have the NWA/WAC exit sub command mode.•Include write commands in your scripts. Otherwise the changes will be lost when the NWA/WAC restarts. You could use multiple write commands in a long script.Note: “exit” or “!'” must follow sub commands if it is to make the NWA/WAC exit sub command mode.I cannot get the firmware uploaded using the commands.The Web Configurator is the recommended method for uploading firmware.

NWA5000 / WAC6500 Series User’s Guide188APPENDIX   AImporting CertificatesThis appendix shows you how to import public key certificates into your web browser. Public key certificates are used by web browsers to ensure that a secure web site is legitimate. When a certificate authority such as VeriSign, Comodo, or Network Solutions, to name a few, receives a certificate request from a website operator, they confirm that the web domain and contact information in the request match those on public record with a domain name registrar. If they match, then the certificate is issued to the website operator, who then places it on the site to be issued to all visiting web browsers to let them know that the site is legitimate.Many ZyXEL products, such as the NWA/WAC, issue their own public key certificates. These can be used by web browsers on a LAN or WAN to verify that they are in fact connecting to the legitimate device and not one masquerading as it. However, because the certificates were not issued by one of the several organizations officially recognized by the most common web browsers, you will need to import the ZyXEL-created certificate into your web browser and flag that certificate as a trusted authority.Note: You can see if you are browsing on a secure website if the URL in your web browser’s address bar begins with  https:// or there is a sealed padlock icon ( ) somewhere in the main browser window (not all browsers show the padlock in the same location).Internet ExplorerThe following example uses Microsoft Internet Explorer 7 on Windows XP Professional; however, they can also apply to Internet Explorer on Windows Vista.

NWA5000 / WAC6500 Series User’s Guide201APPENDIX   BIPv6OverviewIPv6 (Internet Protocol version 6), is designed to enhance IP address size and features. The increase in IPv6 address size to 128 bits (from the 32-bit IPv4 address) allows up to 3.4 x 1038 IP addresses. IPv6 AddressingThe 128-bit IPv6 address is written as eight 16-bit hexadecimal blocks separated by colons (:). This is an example IPv6 address 2001:0db8:1a2b:0015:0000:0000:1a2f:0000. IPv6 addresses can be abbreviated in two ways:• Leading zeros in a block can be omitted. So 2001:0db8:1a2b:0015:0000:0000:1a2f:0000 can be written as 2001:db8:1a2b:15:0:0:1a2f:0. • Any number of consecutive blocks of zeros can be replaced by a double colon. A double colon can only appear once in an IPv6 address. So 2001:0db8:0000:0000:1a2f:0000:0000:0015 can be written as 2001:0db8::1a2f:0000:0000:0015, 2001:0db8:0000:0000:1a2f::0015, 2001:db8::1a2f:0:0:15 or 2001:db8:0:0:1a2f::15.Prefix and Prefix LengthSimilar to an IPv4 subnet mask, IPv6 uses an address prefix to represent the network address. An IPv6 prefix length specifies how many most significant bits (start from the left) in the address compose the network address. The prefix length is written as “/x” where x is a number. For example, 2001:db8:1a2b:15::1a2f:0/32means that the first 32 bits (2001:db8) is the subnet prefix. Link-local AddressA link-local address uniquely identifies a device on the local network (the LAN). It is similar to a “private IP address” in IPv4. You can have the same link-local address on multiple interfaces on a device. A link-local unicast address has a predefined prefix of fe80::/10. The link-local unicast address format is as follows.Table 84   Link-local Unicast Address Format1111 1110 10 0 Interface ID10 bits 54 bits 64 bits
Appendix B IPv6NWA5000 / WAC6500 Series User’s Guide202Global AddressA global address uniquely identifies a device on the Internet. It is similar to a “public IP address” in IPv4. A global unicast address starts with a 2 or 3. Unspecified AddressAn unspecified address (0:0:0:0:0:0:0:0 or ::) is used as the source address when a device does not have its own address. It is similar to “0.0.0.0” in IPv4.Loopback AddressA loopback address (0:0:0:0:0:0:0:1 or ::1) allows a host to send packets to itself. It is similar to “127.0.0.1” in IPv4.Multicast AddressIn IPv6, multicast addresses provide the same functionality as IPv4 broadcast addresses. Broadcasting is not supported in IPv6. A multicast address allows a host to send packets to all hosts in a multicast group. Multicast scope allows you to determine the size of the multicast group. A multicast address has a predefined prefix of ff00::/8. The following table describes some of the predefined multicast addresses. The following table describes the multicast addresses which are reserved and can not be assigned to a multicast group.

 Appendix B IPv6NWA5000 / WAC6500 Series User’s Guide203Subnet MaskingBoth an IPv6 address and IPv6 subnet mask compose of 128-bit binary digits, which are divided into eight 16-bit blocks and written in hexadecimal notation. Hexadecimal uses four bits for each character (1 ~ 10, A ~ F). Each block’s 16 bits are then represented by four hexadecimal characters. For example, FFFF:FFFF:FFFF:FFFF:FC00:0000:0000:0000.Interface IDIn IPv6, an interface ID is a 64-bit identifier. It identifies a physical interface (for example, an Ethernet port) or a virtual interface (for example, the management IP address for a VLAN). One interface should have a unique interface ID.EUI-64The EUI-64 (Extended Unique Identifier) defined by the IEEE (Institute of Electrical and Electronics Engineers) is an interface ID format designed to adapt with IPv6. It is derived from the 48-bit (6-byte) Ethernet MAC address as shown next. EUI-64 inserts the hex digits fffe between the third and fourth bytes of the MAC address and complements the seventh bit of the first byte of the MAC address. See the following example. Stateless AutoconfigurationWith stateless autoconfiguration in IPv6, addresses can be uniquely and automatically generated. Unlike DHCPv6 (Dynamic Host Configuration Protocol version six) which is used in IPv6 stateful autoconfiguration, the owner and status of addresses don’t need to be maintained by a DHCP server. Every IPv6 device is able to generate its own and unique IP address automatically when IPv6 is initiated on its interface. It combines the prefix and the interface ID (generated from its own Ethernet MAC address, see Interface ID and EUI-64) to form a complete IPv6 address.When IPv6 is enabled on a device, its interface automatically generates a link-local address (beginning with fe80).When the interface is connected to a network with a router and the NWA/WAC is set to automatically obtain an IPv6 network prefix from the router for the interface, it generates 1another FF0A:0:0:0:0:0:0:0FF0B:0:0:0:0:0:0:0FF0C:0:0:0:0:0:0:0FF0D:0:0:0:0:0:0:0FF0E:0:0:0:0:0:0:0FF0F:0:0:0:0:0:0:0Table 86   Reserved Multicast Address (continued)MULTICAST ADDRESSTable 87                   MAC 00 : 13 : 49 : 12 : 34 : 56Table 88        EUI - 6 4 02: 13 : 49 : FF : FE : 12 : 34 : 56
Appendix B IPv6NWA5000 / WAC6500 Series User’s Guide204address which combines its interface ID and global and subnet information advertised from the router. This is a routable global IP address.DHCPv6The Dynamic Host Configuration Protocol for IPv6 (DHCPv6, RFC 3315) is a server-client protocol that allows a DHCP server to assign and pass IPv6 network addresses, prefixes and other configuration information to DHCP clients. DHCPv6 servers and clients exchange DHCP messages using UDP.Each DHCP client and server has a unique DHCP Unique IDentifier (DUID), which is used for identification when they are exchanging DHCPv6 messages. The DUID is generated from the MAC address, time, vendor assigned ID and/or the vendor's private enterprise number registered with the IANA. It should not change over time even after you reboot the device.Identity AssociationAn Identity Association (IA) is a collection of addresses assigned to a DHCP client, through which the server and client can manage a set of related IP addresses. Each IA must be associated with exactly one interface. The DHCP client uses the IA assigned to an interface to obtain configuration from a DHCP server for that interface. Each IA consists of a unique IAID and associated IP information.The IA type is the type of address in the IA. Each IA holds one type of address. IA_NA means an identity association for non-temporary addresses and IA_TA is an identity association for temporary addresses. An IA_NA option contains the T1 and T2 fields, but an IA_TA option does not. The DHCPv6 server uses T1 and T2 to control the time at which the client contacts with the server to extend the lifetimes on any addresses in the IA_NA before the lifetimes expire. After T1, the client sends the server (S1 ) (from which the addresses in the IA_NA were obtained) a Renew message. If the time T2 is reached and the server does not respond, the client sends a Rebind message to any available server (S2 ). For an IA_TA, the client may send a Renew or Rebind message at the client's discretion.  DHCP Relay AgentA DHCP relay agent is on the same network as the DHCP clients and helps forward messages between the DHCP server and clients. When a client cannot use its link-local address and a well-known multicast address to locate a DHCP server on its network, it then needs a DHCP relay agent to send a message to a DHCP server that is not attached to the same network.The DHCP relay agent can add the remote identification (remote-ID) option and the interface-ID option to the Relay-Forward DHCPv6 messages. The remote-ID option carries a user-defined string, 1. In IPv6, all network interfaces can be associated with several addresses. T1T2Renew RebindRebindto S1Renewto S1Renewto S1Renewto S1Renewto S1Renewto S1to S2to S2
 Appendix B IPv6NWA5000 / WAC6500 Series User’s Guide205such as the system name. The interface-ID option provides slot number, port information and the VLAN ID to the DHCPv6 server. The remote-ID option (if any) is stripped from the Relay-Reply messages before the relay agent sends the packets to the clients. The DHCP server copies the interface-ID option from the Relay-Forward message into the Relay-Reply message and sends it to the relay agent. The interface-ID should not change even after the relay agent restarts.Prefix DelegationPrefix delegation enables an IPv6 router to use the IPv6 prefix (network address) received from the ISP (or a connected uplink router) for its LAN. The NWA/WAC uses the received IPv6 prefix (for example, 2001:db2::/48) to generate its LAN IP address. Through sending Router Advertisements (RAs) regularly by multicast, the NWA/WAC passes the IPv6 prefix information to its LAN hosts. The hosts then can use the prefix to generate their IPv6 addresses.ICMPv6Internet Control Message Protocol for IPv6 (ICMPv6 or ICMP for IPv6) is defined in RFC 4443.  ICMPv6 has a preceding Next Header value of 58, which is different from the value used to identify ICMP for IPv4. ICMPv6 is an integral part of IPv6. IPv6 nodes use ICMPv6 to report errors encountered in packet processing and perform other diagnostic functions, such as "ping".Neighbor Discovery Protocol (NDP)The Neighbor Discovery Protocol (NDP) is a protocol used to discover other IPv6 devices and track neighbor’s reachability in a network. An IPv6 device uses the following ICMPv6 messages types: • Neighbor solicitation: A request from a host to determine a neighbor’s link-layer address (MAC address) and detect if the neighbor is still reachable. A neighbor being “reachable” means it responds to a neighbor solicitation message (from the host) with a neighbor advertisement message. • Neighbor advertisement: A response from a node to announce its link-layer address.• Router solicitation: A request from a host to locate a router that can act as the default router and forward packets.• Router advertisement: A response to a router solicitation or a periodical multicast advertisement from a router to advertise its presence and other parameters.IPv6 CacheAn IPv6 host is required to have a neighbor cache, destination cache, prefix list and default router list. The NWA/WAC maintains and updates its IPv6 caches constantly using the information from response messages. In IPv6, the NWA/WAC configures a link-local address automatically, and then sends a neighbor solicitation message to check if the address is unique. If there is an address to be resolved or verified, the NWA/WAC also sends out a neighbor solicitation message. When the NWA/WAC receives a neighbor advertisement in response, it stores the neighbor’s link-layer address in the neighbor cache. When the NWA/WAC uses a router solicitation message to query for a router and receives a router advertisement message, it adds the router’s information to the neighbor cache, prefix list and destination cache. The NWA/WAC creates an entry in the default router list cache if the router can be used as a default router.When the NWA/WAC needs to send a packet, it first consults the destination cache to determine the next hop. If there is no matching entry in the destination cache, the NWA/WAC uses the prefix list
Appendix B IPv6NWA5000 / WAC6500 Series User’s Guide206to determine whether the destination address is on-link and can be reached directly without passing through a router. If the address is onlink, the address is considered as the next hop. Otherwise, the NWA/WAC determines the next-hop from the default router list or routing table. Once the next hop IP address is known, the NWA/WAC looks into the neighbor cache to get the link-layer address and sends the packet when the neighbor is reachable. If the NWA/WAC cannot find an entry in the neighbor cache or the state for the neighbor is not reachable, it starts the address resolution process. This helps reduce the number of IPv6 solicitation and advertisement messages.Multicast Listener DiscoveryThe Multicast Listener Discovery (MLD) protocol (defined in RFC 2710) is derived from IPv4's Internet Group Management Protocol version 2 (IGMPv2). MLD uses ICMPv6 message types, rather than IGMP message types. MLDv1 is equivalent to IGMPv2 and MLDv2 is equivalent to IGMPv3.MLD allows an IPv6 switch or router to discover the presence of MLD listeners who wish to receive multicast packets and the IP addresses of multicast groups the hosts want to join on its network.  MLD snooping and MLD proxy are analogous to IGMP snooping and IGMP proxy in IPv4. MLD filtering controls which multicast groups a port can join.MLD MessagesA multicast router or switch periodically sends general queries to MLD hosts to update the multicast forwarding table. When an MLD host wants to join a multicast group, it sends an MLD Report message for that address.An MLD Done message is equivalent to an IGMP Leave message. When an MLD host wants to leave a multicast group, it can send a Done message to the router or switch. The router or switch then sends a group-specific query to the port on which the Done message is received to determine if other devices connected to this port should remain in the group.
 Appendix B IPv6NWA5000 / WAC6500 Series User’s Guide207Example - Enabling IPv6 on Windows XP/2003/VistaBy default, Windows XP and Windows 2003 support IPv6. This example shows you how to use the ipv6 install command on Windows XP/2003 to enable IPv6. This also displays how to use the ipconfig command to see auto-generated IP addresses.IPv6 is installed and enabled by default in Windows Vista. Use the ipconfig command to check your automatic configured IPv6 address as well. You should see at least one IPv6 address available for the interface on your computer.Example - Enabling DHCPv6 on Windows XPWindows XP does not support DHCPv6. If your network uses DHCPv6 for IP address assignment, you have to additionally install a DHCPv6 client software on your Windows XP. (Note: If you use static IP addresses or Router Advertisement for IPv6 address assignment in your network, ignore this section.)This example uses Dibbler as the DHCPv6 client. To enable DHCPv6 client on your computer:1Install Dibbler and select the DHCPv6 client option on your computer.2After the installation is complete, select St a r t  > All Pr ogra m s > Dibbler - DHCPv6  > Clie nt  I nst a ll as se rvice .3Select St a r t  > Control Panel > Adm in ist ra t ive  Tools > Ser vices.4Double click D ibbler -  a D HCPv6  clie nt .C:\>ipv6 installInstalling...Succeeded.C:\>ipconfigWindows IP ConfigurationEthernet adapter Local Area Connection:        Connection-specific DNS Suffix  . :         IP Address. . . . . . . . . . . . : 10.1.1.46        Subnet Mask . . . . . . . . . . . : 255.255.255.0        IP Address. . . . . . . . . . . . : fe80::2d0:59ff:feb8:103c%4        Default Gateway . . . . . . . . . : 10.1.1.254
