Displays the information related to the LLDP (Link Layer Discovery Protocol) neighbors detected on the specified port or ports.
| all | Specifies all ports on the switch. |
| port_list | Specifies one or more ports or slots and ports. |
| detailed | Shows detailed information on the neighbors. |
N/A.
You must use the detailed parameter to display detailed information about the received LLDP TLVs.
The following example displays LLDP neighbor information for all switch ports:

This command was first available in ExtremeXOS 11.2. Information on the LLDP MED extension and Avaya-Extreme proprietary TLVs was added in ExtremeXOS 11.5.
Additional PoE+ information can appear when present in a Power via MDI TLV received from a neighbor starting in ExtremeXOS 12.5.
"System Name" was added to the ouput in ExtremeXOS 22.1.
Management IP address information was added in ExtremeXOS 22.4.
Port Extension TLV information for bridge port extenders (BPEs) was added in ExtremeXOS 22.5.
