Enabling CDP packet interception

A RUCKUS device can be enabled to intercept and display Cisco Discovery Protocol (CDP) packets.
CDP packet interception is disabled by default on all interfaces. CDP packet interception can be enabled globally to apply to all interfaces. If CDP packet interception is to be disabled for an individual interface, the configuration is applied in interface configuration mode. This task shows how to enable CDP globally, disable CDP on one interface and reenable CDP on the interface.
  1. Enter global configuration mode. 
    device# configure terminal
  2. Globally enable CDP packet interception. 
    device(config)# cdp run
  3. Enter interface configuration mode. 
    device(config)# interface ethernet 1/1/2
  4. Disable CDP packet interception on Ethernet interface 1/1/2. 
    device(config-if-e1000-1/1/2)# no cdp enable
  5. Reenable CDP packet interception on Ethernet interface 1/1/2. 
    device(config-if-e1000-1/1/2)# cdp enable

The following example enables CDP packet interception globally and disables CDP packet interception on Ethernet interface 1/1/2. 

device# configure terminal
device(config)# cdp run
device(config)# interface ethernet 1/1/2
device(config-if-e1000-1/1/2)# no cdp enable
