NWA5301-NJ User’s Guide 12CHAPTER 1Introduction1.1 Overview The NWA is an in-the-wall IEEE 802.11b/g/n wireless access point that supports Power over Ethernet (PoE) to eliminate the need for power sockets.The NWA extends the range of your existing wired network without additional wiring, providing easy network access to mobile users. You can set up a wireless network with other IEEE 802.11b/g/n compatible devices.In the following example, you connect a PoE switch to a broadband router/modem that has Internet access. You then use the swicth to provide power and Internet access to three NWAs in different rooms via Ethernet cables.You can set the NWA to operate in either standalone AP or managed AP mode. When the NWA is in standalone AP mode, it can serve as a normal AP, 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’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.
Chapter 1 IntroductionNWA5301-NJ User’s Guide 13The NWA controls network access with Media Access Control (MAC) address filtering. It also provides a high level of network traffic security, supporting IEEE 802.1x, Wi-Fi Protected Access (WPA), WPA2 and Wired Equivalent Privacy (WEP) data encryption.Your NWA 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 ModeAn AP controller can use Control And Provisioning of Wireless Access Points (CAPWAP, see RFC 5415) to discover and configure multiple managed APs.The NWA is a standalone AP by default. You can switch the NWA from being a standalone AP to acting as a managed AP to allow it to be managed by an AP controller, such as the NXC2500. To change between management modes, see Chapter 5 on page 50. When the NWA is in standalone AP mode, the NWA is set to have a static management IP address (192.168.1.2) by default. You can use either the web configurator or FTP to upload firmware. See Section 14.3 on page 156 for more information about firmware uploading.When the NWA 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 back to standalone AP mode, you need to check the AP controller for the NWA’s IP address and use FTP to upload firmware for standalone AP mode.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 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, VoIP_SSID users have QoS priority, SSID01 is the wireless network for standard users, and Guest_SSID is the wireless network for Table 1 NWA Management Mode ComparisonMANAGEMENT MODE DEFAULT IP ADDRESS UPLOAD FIRMWARE VIAStandalone APStatic (192.168.1.2) Web Configurator or FTPManaged AP Dynamic FTP

Chapter 1 IntroductionNWA5301-NJ User’s Guide 151.1.3 Root APIn Root AP mode, the NWA (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 2 Root AP Application On the NWA in Root AP mode, you can have multiple SSIDs active for reqular wireless connections and one SSID for the connection with a repeater (repeater SSID). Wireless clients can use either SSID to associate with the NWA in Root AP mode. A repeater must use the repeater SSID to connect to the NWA in Root AP mode.When the NWA is in Root AP mode, repeater security between the NWA 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 7.2 on page 62 and Section 10.2 on page 94 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 only. 1.1.4 RepeaterThe NWA 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 can extend the range of the WLAN. In the figure below, the NWA in Repeater mode (Z) has a wireless connection to the NWA in Root AP mode (X) which is connected to a wired network and also has a wireless connection to another NWA in Repeater mode (Y) at the same time. Z and Y act as repeaters that forward traffic between associated wireless
Chapter 1 IntroductionNWA5301-NJ User’s Guide16clients and the wired LAN. Clients A and B access the AP and the wired network behind the AP throught repeaters Z and Y.Figure 3 Repeater ApplicationWhen the NWA is in Repeater mode, repeater security between the NWA 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 7.2 on page 62 and Section 10.2 on page 94 for more details. Once the security settings of peer sides match one another, the connection between devices is made.At the time of writing, repeater security is compatible with the NWA only. 1.2 Ways to Manage the NWAYou can use the following ways to manage the NWA.Web ConfiguratorThe Web Configurator allows easy NWA 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. You can access it using remote management (for example, SSH or Telnet). See the Command Reference Guide for more information.
Chapter 1 IntroductionNWA5301-NJ User’s Guide 17File Transfer Protocol (FTP)This protocol can be used for firmware upgrades and configuration backup and restore.Simple Network Management Protocol (SNMP)The NWA can be monitored by an SNMP manager. See the SNMP chapter in this User’s Guide.1.3 Good Habits for Managing the NWADo the following things regularly to make the NWA 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 to its factory default settings. If you backed up an earlier configuration file, you won’t have to totally re-configure the NWA; you can simply restore your last configuration.1.4 Hardware ConnectionsSee your Quick Start Guide for more information on making hardware connections.1.4.1 110 Punch-Down BlockThis section shows you how to use a punch-down tool to seat an 8-wire Ethernet cable to the 110 punch-down block. You can connect a PoE switch to the 110 punch-down block to provide power and Internet access to the NWA through this connection. An 8-pin Ethernet cable has four pairs of color coded wires.1Cut out one and a half inches of the jacket from the Ethenet cable to expose the wires. 2Untwist the wire pairs no more than one inch.
Chapter 1 IntroductionNWA5301-NJ User’s Guide183Match each wire to the correct slot according to the color codes for wiring shown below. 4Use a punch-down tool to seat the wires down properly into the slot.

The NWA powers up, checks the hardware, and starts the system processes.Rebooting the NWA A warm start (without powering down and powering up again) occurs when you use the Reboot button in the Reboot screen or when you use the reboot command. The NWA writes all cached data to the local storage, stops the system processes, and then does a warm start. Using the RESET buttonIf you press the RESET button on the back of the NWA, the NWA sets the configuration to its default values and then reboots. See Section 18.6 on page 171 for more information.Clicking Maintenance > Shutdown > Shutdown or using the shutdown commandClicking Maintenance > Shutdown > Shutdown or using the shutdown command writes all cached data to the local storage and stops the system processes. Wait for the device to shut down and then manually turn off or remove the power. It does not turn off the power. Disconnecting the powerPower off occurs when you turn off the power to the NWA. The NWA simply turns off. It does not stop the system processes or write cached data to local storage.

NWA5301-NJ User’s Guide 50CHAPTER 5Management Mode5.1 OverviewThis chapter discusses using the NWA in management mode, which determines whether the NWA is used in its default standalone mode, or as part of a Control And Provisioning of Wireless Access Points (CAPWAP) network. 5.2 About CAPWAPThe NWA 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 ~ M4). Figure 23 CAPWAP Network ExampleNote: The NWA can be a standalone AP (default), or a CAPWAP managed AP.5.2.1 CAPWAP Discovery and ManagementThe link between CAPWAP-enabled access points proceeds as follows:
Chapter 5 Management ModeNWA5301-NJ User’s Guide 511An 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 Manual mode it adds the details of the AP to its Unmanaged Access Points list, and you decide which available APs to manage. If the AP is in Always Accept mode, it automatically adds the AP to its Managed 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.5.2.2 Managed AP Finds the ControllerA managed NWA can find the controller in one of the following ways:• Manually specify the controller’s IP address in the Web Configurator’s MGNT Mode screen. • Get the controller’s IP address from a DHCP server with the controller’s IP address configured as option 138.• 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.5.2.3 CAPWAP 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.
Chapter 5 Management ModeNWA5301-NJ User’s Guide52DHCP 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 24 CAPWAP and DHCP Option 138 5.2.4 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.5.3 Management Mode ScreenUse this screen to configure the NWA as a CAPWAP managed AP, or to use it in its default standalone mode. To access this screen, click Configuration > MGNT Mode.
Chapter 5 Management ModeNWA5301-NJ User’s Guide 53Note: After you change the operation mode, the NWA resets to its default settings for the mode you set it to, including the IP address of 192.168.1.2 (in standalone AP mode).

NWA5301-NJ User’s Guide 54CHAPTER 6Network6.1 OverviewThis chapter describes how you can configure the management IP address and VLAN settings of your NWA.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 26 IP SetupThe figure above illustrates one possible setup of your NWA. The gateway IP address is 192.168.1.1 and the IP address of the NWA is 192.168.1.2 (default). The gateway and the NWA must belong in the same subnet mask to be able to communicate with each other.6.1.1 What You Can Do in this Chapter•The IP Setting screen (Section 6.2 on page 55) configures the NWA’s LAN IP address. •The VLAN screen (Section 6.3 on page 57) configures the NWA’s VLAN settings.

Chapter 6 NetworkNWA5301-NJ User’s Guide 576.3 VLANThis section discusses how to configure the NWA’s VLAN settings.Figure 28 Management VLAN SetupIn the figure above, to access and manage the NWA from computer A, the NWA and switch B’s ports to which computer A and the NWA 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.In Multi-Tenant Unit (MTU) applications, VLAN is vital in providing isolation and security among the subscribers. When properly configured, VLAN prevents one subscriber from accessing the network resources of another on the same LAN, thus a user will not see the printers and hard disks of another user in the same building. 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. AB

NWA5301-NJ User’s Guide 61CHAPTER 7Wireless7.1 OverviewThis chapter discusses how to configure the wireless network settings in your NWA. The following figure provides an example of a wireless network.Figure 32 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 is the AP.7.1.1 What You Can Do in this Chapter•The AP Management screen (Section 7.2 on page 62) manages the NWA’s general wireless settings.•The Load Balancing screen (Section 7.3 on page 63) configures network traffic load balancing between the APs and the NWA. •The DCS screen (Section 7.4 on page 66) configures dynamic radio channel selection.
Chapter 7 WirelessNWA5301-NJ User’s Guide627.1.2 What You Need to KnowThe following terms and concepts may help as you read this chapter.Station / Wireless ClientA station or wireless client is any wireless-capable device that can connect to an AP using a wireless signal.Dynamic Channel Selection (DCS)Dynamic Channel Selection (DCS) is a feature that allows an AP to automatically select the radio channel upon which it broadcasts by scanning the area around it and determining what channels are currently being used by other devices.Load Balancing (Wireless)Wireless load balancing is the process where you limit the number of connections allowed on an wireless access point (AP) or you limit the amount of wireless traffic transmitted and received on it so the AP does not become overloaded. 7.2 AP ManagementUse this screen to manage the NWA’s general wireless settings.

Chapter 7 WirelessNWA5301-NJ User’s Guide64Each field is described in the following table. 7.3.1 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.For 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 Table 29 Configuration > Wireless > Load BalancingLABEL DESCRIPTIONEnable Load BalancingSelect this to enable load balancing on the NWA.Mode Select a mode by which load balancing is carried out.Select By Station Number to balance network traffic based on the number of specified stations connect to an AP.Select By Traffic Level to balance network traffic based on the volume generated by the stations connected to an AP.Once the threshold is crossed (either the maximum station numbers or with network traffic), then the AP 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 an AP begins load balancing its connections.Traffic Level Select the threshold traffic level at which the AP begins load balancing its connections (Low, Medium, High).Disassociate station when overloadedSelect 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 and is as follows:•Idle Timeout - 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 Strength.•Signal Strength - 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.Reset Click Reset to return the screen to its last-saved settings.
Chapter 7 WirelessNWA5301-NJ User’s Guide 65until it can afford the bandwidth or the laptop is picked up by a different AP with bandwidth to spare.Figure 35 Delaying a ConnectionThe second response your AP can take is to kick the connections that are pushing it over its balanced bandwidth allotment.Figure 36 Kicking a ConnectionConnections are kicked based on either idle timeout or signal strength. The NWA 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 analyzes is signal strength. Devices with the weakest signal strength are kicked first.
Chapter 7 WirelessNWA5301-NJ User’s Guide667.4 DCS Use this screen to configure dynamic radio channel selection. Click Configuration > Wireless > DCS to access this screen.Figure 37 Configuration > Wireless > DCS Each field is described in the following table. Table 30 Configuration > Wireless > DCSLABEL DESCRIPTIONSelect Now Click this to have the NWA scan for and select an available channel immediately.Enable Dynamic Channel SelectionSelect this to have the NWA automatically select the radio channel upon which it broadcasts by scanning the area around it and determining what channels are currently being used by other devices.DCS Time Interval Enter a number of minutes. This regulates how often the NWA 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 will then dynamically select the next available clean channel or a channel with lower interference.Enable DCS Client AwareSelect 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 7 WirelessNWA5301-NJ User’s Guide 677.5 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.Load 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.There are two kinds of wireless load balancing available on the NWA: Load balancing by station number 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.2.4 GHz Channel Selection MethodSelect how you want to specify the channels the NWA switches between for 2.4 GHz operation.Select auto to have the NWA display a 2.4 GHz Channel Deployment field you can use to limit channel switching to 3 or 4 channels.Select manual to select the individual channels the NWA switches between. Select channels from the Available channels list and use the right arrow button to move them to the Channels selected list. 2.4 GHz Channel DeploymentThis is available when the 2.4 GHz Channel Selection Method is set to auto.Select Three-Channel Deployment 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 Four-Channel Deployment to limit channel switching to four channels. Depending on the country domain, if the only allowable channels are 1-11 then the NWA uses channels 1, 4, 7, 11 in this configuration; otherwise, the NWA 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.Apply Click Apply to save your changes back to the NWA.Reset Click Reset to return the screen to its last-saved settings. Table 30 Configuration > Wireless > DCS (continued)LABEL DESCRIPTION
Chapter 7 WirelessNWA5301-NJ User’s Guide68For 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.Load balancing by traffic level 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.

NWA5301-NJ User’s Guide 76CHAPTER 9AP Profile9.1 OverviewThis chapter shows you how to configure preset wireless profiles for the NWA. 9.1.1 What You Can Do in this Chapter•The Radio screen (Section 9.2 on page 77) creates radio configurations that can be used by the APs.•The SSID screen (Section 9.3 on page 82) configures three different types of profiles for your networked APs.9.1.2 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 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:•Radio - This profile type defines the properties of an AP’s radio transmitter. You can have a maximum of 32 radio profiles on the NWA.•SSID - 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.•Security - 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.•MAC Filtering - 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.•Layer-2 Isolation - 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 9 AP ProfileNWA5301-NJ User’s Guide 77WEPWEP (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.WPA and WPA2Wi-Fi Protected Access (WPA) is a subset of the IEEE 802.11i standard. WPA2 (IEEE 802.11i) is a wireless security standard that defines stronger encryption, authentication and key management than WPA. Key differences between WPA(2) 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. 9.2 RadioThis screen allows you to create radio profiles for the NWA.

Spaces and underscores are allowed.802.11 Band Select the wireless band which this radio profile should use.2.4 GHz is the frequency used by IEEE 802.11b/g/n wireless clients.Mode If you set 802.11 Band to 2.4G, you can select from the following:•b/g: allows either IEEE 802.11b or IEEE 802.11g compliant WLAN devices to associate with the NWA. The NWA adjusts the transmission rate automatically according to the wireless standard supported by the wireless devices.•b/g/n: allows IEEE802.11b, IEEE802.11g and IEEE802.11n compliant WLAN devices to associate with the NWA. The transmission rate of your NWA might be reduced.Channel Select the wireless channel which this radio profile should use. It is recommended that you choose the channel least in use by other APs in the region where this profile will be implemented. This will reduce the amount of interference between wireless clients and the AP to which this profile is assigned.Advanced SettingsChannel Width Select the channel bandwidth you want to use for your wireless network.Select Auto to allow the NWA to adjust the channel bandwidth depending on network conditions.Select 20 MHz if you want to lessen radio interference with other wireless devices in your neighborhood.Guard Interval Set the guard interval for this radio profile to either short or long.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.
Chapter 9 AP ProfileNWA5301-NJ User’s Guide 81RTS/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.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.Output Power Set the output power of the AP in this field. If there is a high density of APs in an area, decrease the output power of the NWA5160N to reduce interference with other APs. Select one of the following Max, -3db (50%), -6db (25%), -9dB (12.5%) or Min. See the product specifications for more information on your NWA’s output power.Note: Reducing the output power also reduces the NWA’s effective broadcast radius.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 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 Rate Configuration This section controls the data rates permitted for clients. For each rate, select a rate option from its list. The rates are:•Basic Rate (Mbps) - Set the basic rate configuration in Mbps. Clients can always connect to the NWA at this speed.•Support Rate (Mbps) - Set the support rate configuration in Mbps. Clients can connect to the NWA at this speed, when permitted to do so by the NWA.•MCS Rate - Set the MCS rate configuration. EEE 802.11n supports many different data rates which are called MCS rates. MCS stands for Modulation and Coding Scheme. This is an 802.11n feature that increases the wireless network performance in terms of throughput.

Chapter 9 AP ProfileNWA5301-NJ User’s Guide829.3 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.9.3.1 SSID List This screen allows you to create and manage SSID configurations that can be used by the APs. An SSID, or Service Set IDentifier, is basically the name of the wireless network to which a wireless client can connect. The SSID appears as readable text to any device capable of scanning for wireless frequencies (such as the WiFi adapter in a laptop), and is displayed as the wireless network name when a person makes a connection to it. To access this screen click Configuration > Object > AP Profile > SSID.Transmission Mode Specify how the NWA handles wireless multicast traffic.Select Multicast to Unicast 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 Fixed Multicast 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 Transmission Mode to Fixed Multicast Rate, select a data rate at which the NWA transmits multicast packets to wireless clients. For example, to deploy 4 Mbps video, select a fixed multicast rate higher than 4 Mbps.MBSSID Settings This section displays if you set the Operating Mode to MBSSID. It allows you to associate an SSID profile with the radio profile.Edit Select an SSID and click this button to reassign it.

If none exist, you can use the Create new Object menu to create one.Note: It is highly recommended that you create security profiles for all of your SSIDs to enhance your network security.MAC Filtering ProfileSelect a MAC filtering profile from the list to associate with this SSID. If none exist, you can sue the Create new Object menu to create one.MAC filtering allows you to limit the wireless clients connecting to your network through a particular SSID by wireless client MAC addresses. Any clients that have MAC addresses not in the MAC filtering profile of allowed addresses are denied connections.The disable setting means no MAC filtering is used.
Chapter 9 AP ProfileNWA5301-NJ User’s Guide 859.4 Security ListThis screen allows you to manage wireless security configurations that can be used by your SSIDs. Wireless security is implemented strictly between the AP broadcasting the SSID and the stations that are connected to it.Layer-2 Isolation ProfileSelect a layer-2 isolation profile from the list to associate with this SSID. If none exist, you can sue the Create new Object menu to create one.Layer-2 isolation allows you to prevent wireless clients associated with your NWA from communicating with other wireless clients, APs, computers or routers in a network.The disable setting means no layer-2 isolation is used.QoS Select a Quality of Service (QoS) access category to associate with this SSID. 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.WMM: Enables automatic tagging of data packets. The NWA 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.WMM_VOICE: 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.WMM_VIDEO: All wireless traffic to the SSID is tagged as video data. This is recommended for activities like video conferencing.WMM_BEST_EFFORT: 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.WMM_BACKGROUND: 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 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 an 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.Note: If you associate a layer-2 isolation profile with the SSID, this option will be selected automatically and cannot be configured.OK Click OK to save your changes back to the NWA.Cancel Click Cancel to exit this screen without saving your changes.Table 39 Configuration > Object > AP Profile > Add/Edit SSID Profile (continued)LABEL DESCRIPTION

NWA5301-NJ User’s Guide 96CHAPTER 11Certificates11.1 OverviewThe NWA 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 Certificate screens (Section 11.2 on page 99) generate and export self-signed certificates or certification requests and import the NWA’s CA-signed certificates.•The Trusted Certificates screens (Section 11.3 on page 107) save CA certificates and trusted remote host certificates to the NWA. The NWA 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 CertificatesNWA5301-NJ User’s Guide 975Additionally, Jenny uses her own private key to sign a message and Tim uses Jenny’s public key to verify the message.The NWA 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 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 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 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 act as a certification authority and sign its own certificates.Factory Default CertificateThe NWA 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 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 CertificatesNWA5301-NJ User’s Guide98• 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. 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, 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 Certificate window. Click the Details tab and scroll down to the Thumbprint Algorithm and Thumbprint fields. 4Use a secure method to verify that the certificate owner has the same information in the Thumbprint Algorithm and Thumbprint fields. The secure method may very based on your situation. Possible examples would be over the telephone or through an HTTPS connection.

With OCSP the NWA 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 only gets information on the certificates that it needs to verify, not a huge list. When the NWA requests certificate status information, the OCSP server returns a “expired”, “current” or “unknown” response.Table 54 Configuration > Object > Certificate > Trusted Certificates > ImportLABEL DESCRIPTIONFile Path Type in the location of the file you want to upload in this field or click Browse to find it.You cannot import a certificate with the same name as a certificate that is already in the NWA.Browse Click Browse to find the certificate file you want to upload.

Chapter 12 SystemNWA5301-NJ User’s Guide11812.4 WWW OverviewThe following figure shows secure and insecure management of the NWA coming in from the WAN. HTTPS and SSH access are secure. HTTP, Telnet, and FTP management access are not secure. Figure 65 Secure and Insecure Service Access From the WAN12.4.1 Service Access LimitationsA service cannot be used to access the NWA when you have disabled that service in the corresponding screen.12.4.2 System TimeoutThere is a lease timeout for administrators. The NWA 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 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 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 96 for more information).
Chapter 12 SystemNWA5301-NJ User’s Guide 119HTTPS on the NWA is used so that you can securely access the NWA using the Web Configurator. The SSL protocol specifies that the HTTPS server (the NWA) must always authenticate itself to the HTTPS client (the computer which requests the HTTPS connection with the NWA), whereas the HTTPS client only should authenticate itself when the HTTPS server requires it to do so (select Authenticate Client Certificates in the WWW screen). Authenticate Client Certificates is optional and if selected means the HTTPS client must send the NWA a certificate. You must apply for a certificate for the browser from a CA that is a trusted CA on the NWA.Please refer to the following figure.1HTTPS connection requests from an SSL-aware web browser go to port 443 (by default) on the NWA’s web server.2HTTP connection requests from a web browser go to port 80 (by default) on the NWA’s web server.Figure 66 HTTP/HTTPS ImplementationNote: If you disable HTTP in the WWW screen, then the NWA blocks all HTTP connection attempts.

The issuing certificate authority of the NWA's factory default certificate is the NWA itself since the certificate is a self-signed certificate.
Chapter 12 SystemNWA5301-NJ User’s Guide 123• 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 172 for details.12.4.5.4 Enrolling and Importing SSL Client CertificatesThe SSL client needs a certificate if Authenticate Client Certificates is selected on the NWA. You must have imported at least one trusted CA to the NWA in order for the Authenticate Client Certificates to be active (see the Certificates chapter for details). Apply for a certificate from a Certification Authority (CA) that is trusted by the NWA (see the NWA’s Trusted Certificates Web Configurator screen).Figure 71 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’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 (A) for a management session.Figure 72 SSH Communication Over the WAN Example
Chapter 12 SystemNWA5301-NJ User’s Guide 12912.5.1 How SSH WorksThe following figure is an example of how a secure connection is established between two remote hosts using SSH v1.Figure 73 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.
Chapter 12 SystemNWA5301-NJ User’s Guide13012.5.2 SSH Implementation on the NWAYour NWA supports SSH versions 1 and 2 using RSA authentication and four encryption methods (AES, 3DES, Archfour, and Blowfish).

Chapter 12 SystemNWA5301-NJ User’s Guide134(SNMPv1), version two (SNMPv2c), and version three (SNMPv3). The next figure illustrates an SNMP management operation. Figure 80 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). 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.
Chapter 12 SystemNWA5301-NJ User’s Guide 13512.8.1 Supported MIBsThe NWA supports MIB II that is defined in RFC-1213 and RFC-1215. The NWA also supports private MIBs (ZYXEL-ES-CAPWAP.MIB, ZYXEL-ES-COMMON.MIB, ZYXEL-ES-HYBRIDAP.MIB, ZYXEL-ES-PROWLAN.MIB, ZYXEL-ES-RFMGMT.MIB, ZYXEL-ES-SMI.MIB, and ZYXEL-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’s MIBs from www.zyxel.com.12.8.2 SNMP TrapsThe NWA will send traps to the SNMP manager when any one of the following events occurs.12.8.3 Configuring SNMP To change your NWA’s SNMP settings, click Configuration > System > SNMP tab.

NWA5301-NJ User’s Guide 150CHAPTER 14File Manager14.1 OverviewConfiguration files define the NWA’s settings. Shell scripts are files of commands that you can store on the NWA and run when you need them. You can apply a configuration file or run a shell script without the NWA restarting. You can store multiple configuration files and shell script files on the NWA. You can edit configuration files or shell scripts in a text editor and upload them to the NWA. Configuration files use a .conf extension and shell scripts use a .zysh extension.14.1.1 What You Can Do in this Chapter•The Configuration File screen (Section 14.2 on page 151) stores and names configuration files. You can also download and upload configuration files.•The Firmware Package screen (Section 14.3 on page 156) checks your current firmware version and uploads firmware to the NWA.•The Shell Script screen (Section 14.4 on page 158) 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 uses the factory default settings for any features that the configuration file does not include. When you run a shell script, the NWA 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 ManagerNWA5301-NJ User’s Guide 151While configuration files and shell scripts have the same syntax, the NWA 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 Privilege 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 Configuration 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 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 exit sub command mode.Note: “exit” or “!'” must follow sub commands if it is to make the NWA 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 processes the file line-by-line. The NWA checks the first line and applies the line if no errors are detected. Then it continues with the next line. If the NWA 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 ignores any errors in the configuration file or shell script and applies all of the valid commands. The NWA still generates a log for any errors. 14.2 Configuration FileClick Maintenance > File Manager > Configuration File to open this screen. Use the Configuration File screen to store, run, and name configuration files. You can also download Table 70 Configuration Files and Shell Scripts in the NWAConfiguration Files (.conf) Shell Scripts (.zysh)• Resets to default configuration.•Goes into CLI Configuration mode.• Runs the commands in the configuration file.•Goes into CLI Privilege mode.• Runs the commands in the shell script.

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 startup-config.conf when you restart the NWA (whether through a management interface or by physically turning the power off and back on), the NWA uses the system-default.conf configuration file with the NWA’s default settings.•If there is a startup-config.conf, the NWA checks it for errors and applies it. If there are no errors, the NWA uses it and copies it to the lastgood.conf configuration file as a back up file. If there is an error, the NWA generates a log and copies the startup-config.conf configuration file to the startup-config-bad.conf configuration file and tries the existing lastgood.conf configuration file. If there isn’t a lastgood.conf configuration file or it also has an error, the NWA applies the system-default.conf configuration file.• You can change the way the startup-config.conf file is applied. Include the setenv-startup stop-on-error off command. The NWA ignores any errors in the startup-config.conf file and applies all of the valid commands. The NWA still generates a log for any errors. Figure 88 Maintenance > File Manager > Configuration File Do not turn off the NWA while configuration file upload is in progress.

The Internet connection is slow or intermittent.1There might be a lot of traffic on the network. Look at the LED, and check Section 1.5 on page 20. If the NWA is sending or receiving a lot of information, try closing some programs that use the Internet, especially peer-to-peer applications. 2Check the signal strength. If the signal is weak, try moving the NWA closer to the NWA (if possible), and look around to see if there are any devices that might be interfering with the wireless network (microwaves, other wireless networks, and so on).3Reboot the NWA. 4If the problem continues, contact the network administrator or vendor, or try one of the advanced suggestions.Advanced SuggestionsCheck the settings for QoS. If it is disabled, you might consider activating it. If it is enabled, you might consider raising or lowering the priority for some applications.18.5 Wireless ConnectionsI cannot access the NWA or ping any computer from the WLAN.
Chapter 18 TroubleshootingNWA5301-NJ User’s Guide 1691Make sure the wireless LAN (wireless radio) is enabled on the NWA.2Make sure the radio or at least one of the NWA’s radios is operating in AP mode.3Make sure the wireless adapter (installed on your computer) is working properly.4Make sure the wireless adapter (installed on your computer) is IEEE 802.11 compatible and supports the same wireless standard as the NWA’s active radio.5Make sure your computer (with a wireless adapter installed) is within the transmission range of the NWA.6Check that both the NWA and your computer are using the same wireless and wireless security settings.Hackers have accessed my WEP-encrypted wireless LAN.WEP is extremely insecure. Its encryption can be broken by an attacker, using widely-available software. It is strongly recommended that you use a more effective security mechanism. Use the strongest security mechanism that all the wireless devices in your network support. WPA2 or WPA2-PSK is recommended.The wireless security is not following the re-authentication timer setting I specified.If a RADIUS server authenticates wireless stations, the re-authentication timer on the RADIUS server has priority. Change the RADIUS server’s configuration if you need to use a different re-authentication timer setting.I cannot get a certificate to import into the NWA.1For My Certificates, you can import a certificate that matches a corresponding certification request that was generated by the NWA. You can also import a certificate in PKCS#12 format, including the certificate’s public and private keys.2You must remove any spaces from the certificate’s filename before you can import the certificate.3Any 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 currently allows the importation of a PKS#7 file that contains a single certificate.
Chapter 18 TroubleshootingNWA5301-NJ User’s Guide170• 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.• 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. 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 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 exit sub command mode.•Include write commands in your scripts. Otherwise the changes will be lost when the NWA 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 exit sub command mode.I cannot get the firmware uploaded using the commands.The Web Configurator is the recommended method for uploading firmware. You only need to use the command line interface if you need to recover the firmware. See the CLI Reference Guide for how to determine if you need to recover the firmware and how to recover it.Wireless clients are not being load balanced among my APs.• Make sure that all the APs used by the wireless clients in question share the same SSID, security, and radio settings.• Make sure that all the APs are in the same broadcast domain.• Make sure that the wireless clients are in range of the other APs; if they are only in range of a single AP, then load balancing may not be as effective.
Chapter 18 TroubleshootingNWA5301-NJ User’s Guide 171In the Monitor > Wireless > AP Information > Radio List screen, there is no load balancing indicator associated with any APs assigned to the load balancing task.• Check to be sure that the AP profile which contains the load balancing settings is correctly assigned to the APs in question.• The load balancing task may have been terminated because further load balancing on the APs in question is no longer required.18.6 Resetting the NWAIf you cannot access the NWA by any method, try restarting it by turning the power off and then on again. If you still cannot access the NWA by any method or you forget the administrator password(s), you can reset the NWA to its factory-default settings. Any configuration files or shell scripts that you saved on the NWA should still be available afterwards.Use the following procedure to reset the NWA to its factory-default settings. This overwrites the settings in the startup-config.conf file with the settings in the system-default.conf file. Note: This procedure removes the current configuration. 1Make sure the PWR/SYS LED is on and not blinking.2Press the RESET button and hold it until the LED begins to blink. (This usually takes about five seconds.)3Release the RESET button, and wait for the NWA to restart.You should be able to access the NWA using the default settings.18.7 Getting More Troubleshooting HelpSearch for support information for your model at www.zyxel.com for more troubleshooting suggestions.
NWA5301-NJ User’s Guide 172APPENDIX 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, 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.

NWA5301-NJ User’s Guide 185APPENDIX 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 75 Link-local Unicast Address Format1111 1110 10 0 Interface ID10 bits 54 bits 64 bits
Appendix B IPv6NWA5301-NJ User’s Guide186Global 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. Table 76 Predefined Multicast AddressMULTICAST ADDRESS DESCRIPTIONFF01:0:0:0:0:0:0:1 All hosts on a local node.

Appendix B IPv6NWA5301-NJ User’s Guide 187Subnet 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 is set to automatically obtain an IPv6 network prefix from the router for the interface, it generates 1another address which 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 77 Reserved Multicast Address (continued)MULTICAST ADDRESSTable 78 MAC 00 : 13 : 49 : 12 : 34 : 56Table 79 EUI-64 02: 13 : 49 : FF : FE : 12 : 34 : 56
Appendix B IPv6NWA5301-NJ User’s Guide188combines 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.

Appendix B IPv6NWA5301-NJ User’s Guide 189such 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 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 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 maintains and updates its IPv6 caches constantly using the information from response messages. In IPv6, the NWA 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 also sends out a neighbor solicitation message. When the NWA receives a neighbor advertisement in response, it stores the neighbor’s link-layer address in the neighbor cache. When the NWA 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 creates an entry in the default router list cache if the router can be used as a default router.When the NWA 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 uses the prefix list to
Appendix B IPv6NWA5301-NJ User’s Guide190determine 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 determines the next-hop from the default router list or routing table. Once the next hop IP address is known, the NWA looks into the neighbor cache to get the link-layer address and sends the packet when the neighbor is reachable. If the NWA 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 IPv6NWA5301-NJ User’s Guide 191Example - 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 Start > All Programs > Dibbler-DHCPv6 > Client Install as service.3Select Start > Control Panel > Administrative Tools > Services.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
