Cisco Discovery Protocol (CDP) is a device-discovery protocol that
runs on all Cisco network equipment. Each device sends identifying
messages to a multicast address, and each device monitors the messages
sent by other devices. Information in CDP packets is used in network
management software such as CiscoWorks2000.
Use the CDP Setup page to adjust the device's CDP settings. CDP
is enabled by default.
Settings
Cisco Discovery Protocol (CDP)
Select Disabled to disable CDP on the device; select Enabled
to enable CDP on the device. CDP is enabled by default.
Packet Hold Time
The number of seconds other CDP-enabled devices should consider
the CDP information valid. If other devices do not receive another
CDP packet from the device before this time elapses, they should
assume that the device 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 device sends.
The default value is 60. This value should
always be less than the packet hold time.
Individual Port Enable
- Ethernet -- When selected, the device
sends CDP packets through its Ethernet port and monitors the Ethernet
for CDP packets from other devices.
- AP Radio Internal -- When selected,
the device sends CDP packets through its internal radio port and
monitors the internal radio for CDP packets from other devices.
- AP Radio Module -- When selected,
the device sends CDP packets through its radio module port and
monitors the radio module for CDP packets from other devices.
