Cisco Discovery Protocol (CDP)
Find lag 2 naboer med CDP
CDP privides the following information:
- Device identifiers - For example, the configured host name of a switch
- Address list - Up to one Network layer address for each protocol supported
- Port identifier - The name of the local and remote port-in the form of an ASCII character string such as ethernet0
- Capabilities list - For example, whether this device is a router or a switch
- Platform - The hardware platform of the device; for example, a Cisco 7200 series router

Using CDP for Network Discovery
CDP er en sikkerhedsrisiko da den giver information omkring ens udstyr. Det bør derfor slåes fra på porte ud mod brugerne.
Disable globaly:
Router(config)#no cdp run
Disable per interface:
Router(config-if)#no cdp enable
