History

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.
