Figure 9-6 CDP Setup Page

Follow this link path to reach the CDP Setup page:

1.On the Summary Status page, click Setup.

2.On the Setup page, click Cisco Services.

3.On the Cisco Services Setup page, click Cisco Discovery Protocol (CDP).

Settings on the CDP Setup Page

The CDP Setup page contains the following settings:

•Enabled/Disabled—Select Disabled to disable CDP on the access point; select Enabled to enable CDP on the access point. CDP is enabled by default.

•Packet hold time—The number of seconds other CDP-enabled devices should consider the access point’s CDP information valid. If other devices do not receive another CDP packet from the access point before this time elapses they should assume that the access point has gone offline. The default value is 180. The packet hold time should always be greater than the value in the “Packets sent every” field.

•Packets sent every—The number of seconds between each CDP packet the access point sends. The default value is 60. This value should always be less than the packet hold time.

•Individual Interface Enable: Ethernet—When selected, the access point sends CDP packets through its Ethernet port and monitors the Ethernet for CDP packets from other devices.

MIB for CDP

A MIB file is available for use with CDP. The filename is CISCO-CDP-MIB.my, and you can download the MIB at the following URL:
