5.2.6.12 Link Layer Discovery Protocol Configuration
Profile Network Configuration
The Link Layer Discovery Protocol (LLDP) provides a standard way for a controller or access point to advertise information about
themselves to networked neighbors and store information they discover from their peers.
LLDP is neighbor discovery protocol that defines a method for network access devices using Ethernet connectivity to advertise
information about them to peer devices on the same physical LAN and store information about the network. It allows a device
to learn higher layer management and connection endpoint information from adjacent devices.
Using LLDP, an access point is able to advertise its own identification, capabilities and media-specific configuration information
and learn the same information from connected peer devices.
LLDP information is sent in an Ethernet frame at a fixed interval. Each frame contains one Link Layer Discovery Protocol Data
Unit (LLDP PDU). A single LLDP PDU is transmitted in a single 802.3 Ethernet frame.
To set the LLDP configuration:
1. Select the Configuration tab from the Web UI.
2. Select Devices.
3. Select System Profile from the options on left-hand side of the UI.
4. Expand the Network menu and select Link Layer Discovery Protocol.

5. .Set the following LLDP parameters for the profile configuration:
Enable LLDP Select this option to enable LLDP on the access point. LLDP is enabled by default When
enabled, an access point advertises its identity, capabilities and configuration information
to connected peers and learns the same from them.
Hold Time Use the spinner control to set the hold time (in seconds) for transmitted LLDP PDUs. Set a
value from 10 - 1,800. The default hold time is 180 seconds.
Timer Set the interval used to transmit LLDP PDUs. Define an interval from 5 - 900 seconds. The
default setting is 60 seconds.
Inventory Management
Discovery
Select this option to include LLPD-MED inventory management discovery TLV in LLDP
PDUs. This setting is enabled by default.
