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.
This command is available on the Summit X450-G2, X460-G2, X670-G2, X770, and ExtremeSwitching X440-G2, X620, X690, X870 series switches.
