CDP

CDP is a device discovery protocol that runs on all Cisco network equipment. Information in CDP packets is used in network management software such as CiscoWorks2000.

Use the CDP Setup page to adjust the access point CDP settings shown in Figure . CDP is enabled by default.

  • Cisco Discovery Protocol (CDP) – 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 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 Port Enable – Ethernet - When selected, the access point sends CDP packets through its Ethernet port and monitors the Ethernet for CDP packets from other devices.
  • Individual Port Enable – AP Radio - This checkbox appears when the access point radio is linked to another radio infrastructure device, such as an access point, bridge or repeater. When selected, the access point sends CDP packets through the radio port and monitors the radio for CDP packets from other devices.
