Troubleshooting H-REAP (Cisco Wireless LAN Controllers) Part 1

You can verify your H-REAP configuration on the controller and the AP with several show and debug commands, as detailed in the sections that follow.

Show Commands

From the controller CLI, you can see if the AP is in H-REAP mode, what the local VLAN mappings are, its backup RADIUS servers, groups, and so on, and the state of a client associated with an H-REAP WLAN. The commands from the controller CLI are as follows:


■ show ap config general AP_name: Displays VLAN configurations, static backup RADIUS servers, and H-REAP group information.

■ show wlan wlan_id: Displays whether the WLAN is locally or centrally switched.

■ show client detail client_mac: Displays whether the client is locally or centrally switched.

Examples 13-4, 13-5, and 13-6 provide sample output from these three commands on the controller respectively.

Example 13-4 show ap config general Command Output

The show commands on the H-REAP AP can show you the state of the AP, the configuration stored in nonvolatile RAM, whether the AP is in connected or standalone mode, the associated clients, traffic statistics, CCKM cache information, and high availability configurations, as well as mobile node (clients) while in connected mode.

The show commands on the AP are as follows:

■ show capwap/lwapp client rcb: Displays AP radio control block information.

■ show capwap client ha: Displays high availability configuration.

■ show capwap/lwapp client mn: Displays mobile node information.

■ show capwap/lwapp client traffic: Displays traffic statistics.

show capwap/lwapp reap association: Displays associated clients.

■ show capwap/lwapp reap cckm: Displays CCKM cache information.

■ show capwap/lwapp reap status: Displays the status of the AP, connected or standalone, as well as any radar information.

The following examples provide the different outputs from these commands. Depending on whether the AP is in connected or standalone mode, the output can change. Example 13-7 shows the output from an AP in connected mode when the operation state is UP.

Example 13-7 show capwap client rcb Command Output

Example 13-7 show capwap client rcb Command Output

Example 13-8 shows the same command output, but this time, the AP is in standalone mode and the operation state is DISCOVERY because the AP is trying to rejoin its controller.

Example 13-8 show capwap client rcb Command Output

show capwap client rcb Command Output

To show whether the AP is in connected or standalone mode, use show capwap/lwapp reap status, as seen in Example 13-9.

Example 13-9 show capwap reap status Command Output

show capwap reap status Command Output

To see the clients currently associated with the AP, use show capwap/lwapp reap association, as shown in Example 13-10.

Example 13-10 show capwap reap association Command Output

show capwap reap association Command Output

Example 13-10 show capwap reap association Command Output

show capwap reap association Command Output

To view CCKM cache entries, use show capwap reap cckm, as shown in Example 13-11. Example 13-11 show capwap reap cckm Command Output

When the AP is in connected mode, you can use show capwap/lwapp client mn to view the mobile node client information, the WLAN it is associated with, and the radio interface. When the AP is in standalone mode, the output is empty. Example 13-12 demonstrates the output from this command.

Example 13-12 show capwap client mn Command Output

show capwap client mn Command Output

You can view the high availability configuration of the AP using show capwap client ha, as shown in Example 13-13. Notice that the IP address of the Primary Backup controller is listed in hex.

Example 13-13 show capwap client ha Command Output

show capwap client ha Command Output

The output of show capwap/lwapp client traffic, as shown in Example 13-14, details traffic statistics for the AP.

Example 13-14 show capwap client traffic Command Output
