Configuring Power over Ethernet
Use these commands to obtain information about CDP neighbors on the controller.
1. To see the status of CDP and to view CDP protocol information, enter this command:
show cdp
2. To see a list of all CDP neighbors on all interfaces, enter this command:
show cdp neighbors [detail]
The optional detail command provides detailed information for the controller’s CDP neighbors.
Note This command shows only the CDP neighbors of the controller. It does not show the CDP
neighbors of the controller’s associated access points.
3. To see all CDP entries in the database, enter this command:
show cdp entry all
4. To see various traffic-related parameters on a given port (for example, packets sent and received,
CRC errors, and so on), enter this command:
show cdp traffic
5. To see the CDP status for a specific access point, enter this command:
show ap cdp Cisco_AP
6. To see the CDP status for all access points that are connected to this controller, enter this command:
show ap cdp all
Use these commands to obtain CDP debug information for the controller.
1. To obtain debug information related to CDP packets, enter this command:
debug cdp packets
2. To obtain debug information related to CDP events, enter this command:
debug cdp events
Configuring Power over Ethernet
When an LWAPP-enabled access point (such as an AP1131 or AP1242) is powered by a power injector
that is connected to a Cisco pre-Intelligent Power Management (pre-IPM) switch, you need to configure
power over Ethernet (PoE), also known as inline power. You can configure PoE through either the GUI
or the CLI.
Using the GUI to Configure Power over Ethernet
Follow these steps to configure PoE using the controller GUI.
Step 1 Click Wireless and then the Detail link of the desired access point. The All APs > Details page appears
(see Figure 7-13).
