Question: What is LLDP (Link Layer Discovery Protocol)? Does Aruba support LLDP?

Environment:This article applies to controllers running AOS version or higher


Link Layer Discovery Protocol (LLDP) - is layer 2 protocol used by network devices for advertising their identity, capabilities, and neighbors on a wired LAN.


From AOS version 6.2 onwards, Aruba supports LLDP on the wired ports of APs. Wired interfaces on Aruba APs support LLDP by periodically transmitting LLDP Protocol Data Units (PDUs).


LLDP-MED (media endpoint devices) is an extension to LLDP that supports interoperability between VoIP and video streaming devices and other networking clients. LLDP-MED network policy discovery lets end-points and network devices advertise the VLAN, priority levels, and DSCP values used by a voice or video application.


You can enable LLDP on wired ports of an AP by:

  1. Navigating to Configuration> AP Configuration> Edit AP Group
  2. Click AP
  3. Expand the Ethernet interface
  4. Click  AP LLDP Profile
