Chapter 1 IntroductionNWA / WAC 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.Table 2 WAC Series Comparison TableFEATURES WAC5302D-S WAC6502D-E WAC6502D-S WAC6503D-S WAC6553D-E WAC6103D-ISupported Wireless StandardsIEEE 802.11aIEEE 802.11bIEEE 802.11gIEEE 802.11nIEEE 802.11acIEEE 802.11aIEEE 802.11bIEEE 802.11gIEEE 802.11nIEEE 802.11acIEEE 802.11aIEEE 802.11bIEEE 802.11gIEEE 802.11nIEEE 802.11acIEEE 802.11aIEEE 802.11bIEEE 802.11gIEEE 802.11nIEEE 802.11acIEEE 802.11aIEEE 802.11bIEEE 802.11gIEEE 802.11nIEEE 802.11acIEEE 802.11aIEEE 802.11bIEEE 802.11gIEEE 802.11nIEEE 802.11acSupported Frequency Bands2.4 GHz5 GHz 2.4 GHz5 GHz 2.4 GHz5 GHz 2.4 GHz5 GHz 2.4 GHz5 GHz 2.4 GHz5 GHzAvailable Security ModesNoneWEPWPA2WPA2-MIXWPA2-PSKWPA2-PSK-MIXNoneWEPWPA2WPA2-MIXWPA2-PSKWPA2-PSK-MIXNoneWEPWPA2WPA2-MIXWPA2-PSKWPA2-PSK-MIXNoneWEPWPA2WPA2-MIXWPA2-PSKWPA2-PSK-MIXNoneWEPWPA2WPA2-MIXWPA2-PSKWPA2-PSK-MIXNoneWEPWPA2WPA2-MIXWPA2-PSKWPA2-PSK-MIXNumber of SSID Profiles 32 32 32 32 32 32Number of Wireless Radios 222222Monitor Mode & Rogue APs Detection No Yes Yes Yes Yes YesWDS (Wireless Distribution System) - Root AP & Repeater ModesNo Yes Yes Yes Yes YesLayer-2 Isolation Yes Yes Yes Yes Yes YesPower Detection Yes Yes Yes Yes Yes NoExternal Antennas No Yes No No Yes NoInternal Antenna Yes No Yes Yes No YesAntenna Switch No No No No No Yes802.11r Fast Roaming Support in Managed AP ModeNo Yes Yes Yes Yes YesMaximum number of log messages 512 event logs or 1024 debug logs
Chapter 1 IntroductionNWA / WAC Series User’s Guide131.1.1 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) Discovery screen (see Section 5.4 on page 68). 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 Discovery screen to have the NWA/WAC work as a managed AP.When 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, VoIP_SSID users have QoS priority, SSID01 is the wireless network for standard users, and Guest_SSID 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.Table 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 IntroductionNWA / WAC 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 IntroductionNWA / WAC 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 use either SSID to
Chapter 1 IntroductionNWA / WAC Series User’s Guide16associate 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 71 and Section 10.2 on page 113 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 71 and Section 10.2 on page 113 for more details. Once the security settings of peer sides match one another, the connection between devices is made.
Chapter 1 IntroductionNWA / WAC 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.

NWA / WAC Series User’s Guide61CHAPTER 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 29 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 ~ M4).
Chapter 5 NetworkNWA / WAC Series User’s Guide62Figure 30 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 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 controller 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.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) Discovery 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 NetworkNWA / WAC Series User’s Guide63CAPWAP 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 31 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 IP Setting screen (Section 5.2 on page 64) configures the NWA/WAC’s LAN IP address. • The VLAN screen (Section 5.3 on page 65) configures the NWA/WAC’s VLAN settings. • The AC (AP Controller) Discovery screen (Section 5.3 on page 65) configures the NWA/WAC’s AP Controller settings.

IP Address Enter the IP address for this interface.Subnet Mask Enter the subnet mask of this interface in dot decimal notation. The subnet mask indicates what part of the IP address is the same for all computers in the network.Gateway Enter the IP address of the gateway. The NWA/WAC sends packets to the gateway when it does not know how to route the packet to its destination. The gateway should be on the same network as the interface.

Chapter 5 NetworkNWA / WAC Series User’s Guide66Figure 33 Management VLAN SetupIn 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. To access this screen, click Configuration > Network > VLAN.AB

NWA / WAC Series User’s Guide70CHAPTER 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 36 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 Management screen (Section 6.2 on page 71) manages the NWA/WAC’s general wireless settings.• The MON Mode screen (Section 6.3 on page 74) 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 76) configures network traffic load balancing between the APs and the NWA/WAC. • The DCS screen (Section 6.5 on page 79) configures dynamic radio channel selection.
Chapter 6 WirelessNWA / WAC Series User’s Guide716.1.2 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. 6.2 AP ManagementUse this screen to manage the NWA/WAC’s general wireless settings.

Table 36 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 Station Number 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 Smart Classroom 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 Station Number or By Traffic 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).The maximum bandwidth allowed for each level is: •Low - 11 Mbps, •Medium - 23 Mbps•High - 35M bpsDisassociate station when overloadedThis function is enabled by default and the disassociation priority is always Signal Strength when you set Mode to By Smart 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:•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/WAC.Reset Click Reset to return the screen to its last-saved settings.
Chapter 6 WirelessNWA / WAC Series User’s Guide786.4.1 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.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 until it can afford the bandwidth or the laptop is picked up by a different AP with bandwidth to spare.Figure 41 Delaying a ConnectionThe second response your AP can take is to kick the connections that are pushing it over its balanced bandwidth allotment.Figure 42 Kicking a ConnectionConnections are kicked based on either idle timeout or signal strength. 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 Configuration > Wireless > DCS to access this screen.Figure 43 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 37 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 Reset to return the screen to its last-saved settings.
Chapter 6 WirelessNWA / WAC Series User’s Guide80Figure 44 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 45 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 46 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.There are three kinds of wireless load balancing available on the NWA/WAC:
Chapter 6 WirelessNWA / WAC Series User’s Guide81Load 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.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.Load balancing by smart classroom also limits the number of devices allowed to connect to your AP. But any new connections will be just rejected when the AP is overloaded.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.

NWA / WAC Series User’s Guide89CHAPTER 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 Radio screen (Section 8.2 on page 90) creates radio configurations that can be used by the APs.• The SSID screen (Section 8.3 on page 96) 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:•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/WAC.•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/WAC.•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/WAC.•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/WAC.•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 8 AP ProfileNWA / WAC Series User’s Guide90WEPWEP (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. A radio profile is a list of settings that an NWA/WAC can use to configure its radio transmitter(s).

Chapter 8 AP ProfileNWA / WAC Series User’s Guide93802.11 Band Select the wireless band which this radio profile should use. Not all NWA/WACs support both 2.4 GHz and 5 GHz frequency bands.2.4 GHz is the frequency used by IEEE 802.11b/g/n wireless clients.5 GHz is the frequency used by IEEE 802.11ac/a/n wireless clients.•11b/g: allows either IEEE 802.11b or IEEE 802.11g compliant WLAN devices to associate with the NWA/WAC. The NWA/WAC adjusts the transmission rate automatically according to the wireless standard supported by the wireless devices.•11b/g/n: allows IEEE802.11b, IEEE802.11g and IEEE802.11n compliant WLAN devices to associate with the NWA/WAC. The transmission rate of your NWA/WAC might be reduced.•11a: allows only IEEE 802.11a compliant WLAN devices to associate with the NWA/WAC.•11a/n: allows both IEEE802.11n and IEEE802.11a compliant WLAN devices to associate with the NWA/WAC. The transmission rate of your NWA/WAC might be reduced.•11ac: 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 20 MHz if you want to lessen radio interference with other wireless devices in your neighborhood.Select 20/40 MHz to allow the NWA/WAC to choose the channel bandwidth (20 or 40 MHz) that has least interference.Select 20/40/80 MHz to allow the NWA/WAC to choose the channel bandwidth (20 or 40 or 80 MHz) that has least interference. This option is available only when you select 11ac in the 802.11 Band field.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.•Manual: Choose from the available radio channels in the list. If your NWA/WAC is outdoor type, be sure to choose non-indoors channels.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.2.4 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 auto to have the NWA/WAC 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/WAC switches between.Note: The method is automatically set to auto when no channel is selected or any one of the previously selected channels is not supported.Channel ID This field is available only when you set Channel Selection to DCS and set 2.4 GHz Channel Selection Method to manual.Select the check boxes of the channels that you want the NWA/WAC to use.Table 44 Configuration > Object > AP Profile > Add/Edit Profile (continued)LABEL DESCRIPTION
Chapter 8 AP ProfileNWA / WAC Series User’s Guide942.4 GHz Channel Deployment This 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/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 This field is available only when you select 11a, 11a/n or 11ac in the 802.11 Band field and set 5 GHz Channel Selection Method to auto. 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 Auto to have the NWA/WAC automatically select the best channel.Select manual to select the individual channels the NWA/WAC switches between.Note: The method is automatically set to auto when no channel is selected or any one of the previously selected channels is not supported.Channel ID This field is available only when you set Channel Selection to DCS and set 5 GHz Channel Selection Method to manual.Select the check boxes of the channels that you want the NWA/WAC to use.Time Interval Select this option to have the NWA/WAC survey the other APs within its broadcast radius at the end of the specified time interval.DCS Time Interval This field is available when you set Channel Selection to DCS and select the Time Interval option.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.Schedule Select this option to have the NWA/WAC survey the other APs within its broadcast radius at a specifc time on selected days of the week.Start Time Specify the time of the day (in 24-hour format) to have the NWA/WAC use DCS to automatically scan and find a less-used channel.Week Days Select each day of the week to have the NWA/WAC use DCS to automatically scan and find a less-used channel.Advanced SettingsGuard Interval Set the guard interval for this radio profile to either short or long. This option isn’t applicable if you set 802.11 Band to 11a or 11b/g and/or 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.Table 44 Configuration > Object > AP Profile > Add/Edit Profile (continued)LABEL DESCRIPTION
Chapter 8 AP ProfileNWA / WAC Series User’s Guide95Enable A-MPDU Aggregation Select this to enable A-MPDU aggregation. This field is not available if you set 802.11 Band to 11a or 11b/g.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. This field is not available if you set 802.11 Band to 11a or 11b/g.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.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 Threshold Set 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 SettingsTable 44 Configuration > Object > AP Profile > Add/Edit Profile (continued)LABEL DESCRIPTION
Chapter 8 AP ProfileNWA / WAC Series User’s Guide968.3 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.8.3.1 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.Note: You can have a maximum of 32 SSID profiles on the NWA/WAC.Figure 53 Configuration > Object > AP Profile > SSID ListTransmission Mode Specify how the NWA/WAC 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/WAC transmits multicast packets to wireless clients. For example, to deploy 4 Mbps video, select a fixed multicast rate higher than 4 Mbps.OK Click OK to save your changes back to the NWA/WAC.Cancel Click Cancel to exit this screen without saving your changes.Table 44 Configuration > Object > AP Profile > Add/Edit Profile (continued)LABEL DESCRIPTION

This name is only visible in the Web Configurator and is only for management purposes. Spaces and underscores are allowed.SSID Enter the SSID name for this profile. This is the name visible on the network to wireless clients. Enter up to 32 characters, spaces and underscores are allowed.Security Profile Select a security profile from this list to associate with this SSID. 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 use 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.Layer-2 Isolation ProfileSelect a layer-2 isolation profile from the list to associate with this SSID. If none exist, you can use the Create new Object menu to create one.Layer-2 isolation allows you to prevent wireless clients associated with your NWA/WAC 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/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.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.Rate LimitingDownlink Define the maximum incoming transmission data rate (either in mbps or kbps) on a perstation basis.
