CDP Neighbor detail on a 3com?

[KStanko]

Is there an equivalent command for 3com?   I am used to Cisco and I am trying to trace down a mac and I have no idea what the cdp neighbors are.

The equivalent command is "display ndp". Unfortunately, there is no any command that is equivalent to the "show cdp neighbor DETAILED". The ndp output shows the neighbor platform, the port and MAC address, but does not show the IP address.

Hi everyone,

I'm working on a HP A7503 Switch (JD240B).

I solved the problem enabling the LLDP feature with CDP compliance.

Here the commands step by step:

[HP-A7503-Gigi]display lldp status Global status of LLDP: Disable

[HP-A7503-Gigi]lldp enable

[HP-A7503-Gigi]lldp compliance ?

cdp  Non standard IEEE discovery protocol

[HP-A7503-Gigi]lldp compliance cdp

[HP-A7503-Gigi]display lldp neighbor-information ?
