Support Chassis ID Fallback in LLDP Neighbor Table When System Name Is Absent

Zyxel_Judy

Currently, the Neighbor Table only displays a device’s name if the LLDP System Name TLV is present. If a device sends LLDP without System Name (e.g. a Windows PC), the entry shows blank — even though the Chassis ID is correctly received and stored (verifiable via show lldp info remote).

Therefore, user @matteosaitta would like to request a fallback: when System Name is absent, display the Chassis ID instead, so the entry is still identifiable.

This suggestion originated from the post found here: LLDP chassis name is being ignored in nebula-managed switches
