CH A P T E R 4 Configuring Controller Settings This chapter describes how to configure settings on the controller. It contains these sections: • Installing and Configuring Licenses, page 4-2 • Configuring 802.11 Bands, page 4-26 • Configuring 802.11n Parameters, page 4-30 • Configuring 802.
Chapter 4 Configuring Controller Settings Installing and Configuring Licenses • Resetting the Controller to Default Settings, page 4-120 Installing and Configuring Licenses You can order Cisco 5500 Series Controllers with support for 12, 25, 50, 100, 250 or 500 access points as the controller’s base capacity. You can add additional access point capacity through capacity adder licenses available at 25, 50, 100 and 250 access point capacities.
Chapter 4 Configuring Controller Settings Installing and Configuring Licenses The licensing change can affect features on your wireless LAN when you upgrade or downgrade software releases, so you should be aware of these guidelines: • If you have a WPlus license and you upgrade from 6.0.x.x to 7.0.98.0, your license file contains both Basic and WPlus license features. You won’t see any disruption in feature availability and operation. • If you have a WPlus license and you downgrade from 7.0.98.0 to 6.
Chapter 4 Configuring Controller Settings Installing and Configuring Licenses You can use the capacity adder licenses to increase the number of access points supported by the controller up to a maximum of 500 access points. The capacity adder licenses are available in access point capacities of 10, 25, 50, 100 and 250 access points. You can add these licenses to any of the base capacity licenses of 12, 25, 50, 100 and 250 access points.

Chapter 4 Configuring Controller Settings Configuring 802.3 Bridging Configuring 802.3 Bridging The controller supports 802.3 frames and the applications that use them, such as those typically used for cash registers and cash register servers. However, to make these applications work with the controller, the 802.3 frames must be bridged on the controller. Support for raw 802.3 frames allows the controller to bridge non-IP frames for applications not running over IP. Only this raw 802.
Chapter 4 Configuring Controller Settings Configuring 802.3 Bridging Figure 4-22 Step 2 General Page From the 802.3 Bridging drop-down list, choose Enabled to enable 802.3 bridging on your controller or Disabled to disable this feature. The default value is Disabled. Note In controller software release 5.2 or later releases, you can disable 802.3 bridging only for 4400 series controllers, the Cisco WiSM, and the Catalyst 3750G Wireless LAN Controller Switch.
Chapter 4 Configuring Controller Settings Configuring Multicast Mode Configuring Multicast Mode If your network supports packet multicasting, you can configure the multicast method that the controller uses. The controller performs multicasting in two modes: • Unicast mode—In this mode, the controller unicasts every multicast packet to every access point associated to the controller. This mode is inefficient but might be required on networks that do not support multicasting.
Chapter 4 Configuring Controller Settings Configuring Multicast Mode • When the client that is listening to the multicast groups roams from one controller to another, the first controller transmits all the multicast group information for the listening client to the second controller. As a result, the second controller can immediately create the multicast group information for the client.
Chapter 4 Configuring Controller Settings Configuring Multicast Mode • Cisco Flex 7500 Series Controllers do not support multicast-unicast mode. Using the GUI to Enable Multicast Mode To enable multicast mode using the controller GUI, follow these steps: Step 1 Choose Controller > Multicast to open the Multicast page (see Figure 4-23).
Chapter 4 Configuring Controller Settings Configuring Multicast Mode Using the GUI to View Multicast Groups To view multicast groups using the controller GUI, follow these steps: Step 1 Choose Monitor > Multicast. The Multicast Groups page appears (see Figure 4-24). Figure 4-24 Multicast Groups Page This page shows all the multicast groups and their corresponding MGIDs.
Chapter 4 Configuring Controller Settings Configuring Multicast Mode Step 3 Enable or disable IGMP snooping by entering this command: config network multicast igmp snooping {enable | disable} The default value is disabled. Step 4 Set the IGMP timeout value by entering this command: config network multicast igmp timeout timeout You can enter a timeout value between 30 and 7200 seconds.
Chapter 4 Configuring Controller Settings Configuring Client Roaming 00:13:02:23:82:ad 0:20 Using the CLI to View an Access Point’s Multicast Client Table To help troubleshoot roaming events, you can view an access point’s multicast client table from the controller by performing a remote debug of the access point.
Chapter 4 Configuring Controller Settings Configuring Client Roaming Inter-Subnet Roaming Multiple-controller deployments support client roaming across access points managed by controllers in the same mobility group on different subnets. This roaming is transparent to the client because the session is sustained and a tunnel between the controllers allows the client to continue using the same DHCP-assigned or client-assigned IP address as long as the session remains active.
Chapter 4 Configuring Controller Settings Configuring Client Roaming Note To see whether a particular client supports E2E, choose Wireless > Clients on the controller GUI, click the Detail link for the desired client, and look at the E2E Version text box under Client Properties. • Roam reason report—This feature enables CCXv4 clients to report the reason why they roamed to a new access point. It also allows network administrators to build and monitor a roam history.
Chapter 4 Configuring Controller Settings Configuring Client Roaming Figure 4-25 802.11a > Client Roaming Page Step 2 If you want to fine-tune the RF parameters that affect client roaming, choose Custom from the Mode drop-down list and go to Step 3.

Chapter 4 Configuring Controller Settings Configuring Quality of Service Configuring Quality of Service Quality of service (QoS) refers to the capability of a network to provide better service to selected network traffic over various technologies. The primary goal of QoS is to provide priority including dedicated bandwidth, controlled jitter and latency (required by some real-time and interactive traffic), and improved loss characteristics.
Chapter 4 Configuring Controller Settings Configuring Quality of Service Figure 4-26 Edit QoS Profile Page Step 4 Change the description of the profile by modifying the contents of the Description text box. Step 5 Define the average data rate for TCP traffic per user by entering the rate in Kbps in the Average Data Rate text box. You can enter a value between 0 and 60,000 Kbps (inclusive). A value of 0 imposes no bandwidth restriction on the profile.
Chapter 4 Configuring Controller Settings Configuring Quality of Service Step 11 Choose 802.1p from the Protocol Type drop-down list and enter the maximum priority value in the 802.1p Tag text box to define the maximum value (0–7) for the priority tag associated with packets that fall within the profile. The tagged packets include CAPWAP data packets (between access points and the controller) and packets sent toward the core network. Note If a QoS profile has 802.
Chapter 4 Configuring Controller Settings Configuring Quality of Service config qos max-rf-usage {bronze | silver | gold | platinum} usage_percentage Step 8 Define the maximum value (0–7) for the priority tag associated with packets that fall within the profile, by entering these commands: config qos protocol-type {bronze | silver | gold | platinum} dot1p config qos dot1p-tag {bronze | silver | gold | platinum} tag The tagged packets include CAPWAP data packets (between access points and the controller)

You can enter a value between 0 and 60,000 Kbps (inclusive). A value of 0 imposes no bandwidth restriction on the QoS role. Step 7 Define the peak data rate for TCP traffic on a per-user basis by entering the rate in Kbps in the Burst Data Rate text box.
Chapter 4 Configuring Controller Settings Configuring Quality of Service • config netuser guest-role qos data-rate average-realtime-rate role_name rate—Configures the average real-time rate for UDP traffic on a per-user basis. • config netuser guest-role qos data-rate burst-realtime-rate role_name rate—Configures the peak real-time rate for UDP traffic on a per-user basis. Note Note Step 3 The Burst Real-Time Rate should be greater than or equal to the Average Real-Time Rate.
Chapter 4 Configuring Controller Settings Configuring Voice and Video Parameters Configuring Voice and Video Parameters Three parameters on the controller affect voice and/or video quality: • Call admission control • Expedited bandwidth requests • Unscheduled automatic power save delivery Each of these parameters is supported in Cisco Compatible Extensions (CCX) v4 and v5. See the “Configuring Access Point Groups” section on page 7-55 for more information on CCX.
Chapter 4 Configuring Controller Settings Configuring Voice and Video Parameters In load-based CAC, the access point continuously measures and updates the utilization of the RF channel (that is, the percentage of bandwidth that has been exhausted), channel interference, and the additional calls that the access point can admit. The access point admits a new call only if the channel has enough unused bandwidth to support that call.
Chapter 4 Configuring Controller Settings Configuring Voice and Video Parameters U-APSD Unscheduled automatic power save delivery (U-APSD) is a QoS facility defined in IEEE 802.11e that extends the battery life of mobile clients. In addition to extending battery life, this feature reduces the latency of traffic flow delivered over the wireless media.
Chapter 4 Configuring Controller Settings Configuring Voice and Video Parameters Using the GUI to Configure Voice Parameters To configure voice parameters using the controller GUI, follow these steps: Note SIPs are available only on the Cisco 4400 Series and Cisco 5500 Series Controllers, and on the 1240, 1130, and 11n access points. Note SIP CAC should only be used for phones that support status code 17 and do not support TSPEC-based admission control.
Chapter 4 Configuring Controller Settings Configuring Voice and Video Parameters Step 7 • Load-based—To enable channel-based CAC. This is the default option. • Static—To enable radio-based CAC. In the Max RF Bandwidth text box, enter the percentage of the maximum bandwidth allocated to clients for voice applications on this radio band. Once the client reaches the value specified, the access point rejects new calls on this radio band. The range is 5 to 85%.
