LLDP-MED
LLDP-MED (media endpoint devices) is an extension to LLDP that supports interoperability between VoIP
devices and other networking clients. LLDP-MED network policy discovery lets end-points and network devices
advertise their VLAN IDs (for example, voice VLAN), priority levels, and DSCP values. ArubaOS supports a
maximum of eight LLDP -MED Network Policy profiles.
Creating an LLDP MED network policy profile does not apply the configuration to any AP or AP interface or
interface group. To apply the LLDP-MED network policy profile, you must associate it to an LLDP profile, then
apply that LLDP profile to an AP wired port profile.
You can use the command, ap lldp med-network-policy-profile to define an LLDP MED network policy
profile that defines DSCP values and L2 priority levels for a voice or video application.
Default LLDP Configuration
To display the default LLDP information, use the following command:
(host) #show lldp interface gigabitethernet 1/1
Interface: FE1/1
LLDP Tx: Disabled, LLDP Rx: Disabled
Proprietary Neighbor Discovery: Disabled
LLDP-MED: Disabled
Fast Transmit interval: 1, Fast Transmit message counter: 4
Transmit interval: 30, Transmit hold 4, Hold timer: 120
When you use the default LLDP configuration, the RX and TX parameters are disabled. You must explicitly enable
them for LLDP to work.
Configuring LLDP
You can configure LLDP using the CLI. For detailed information on the LLDP commands, refer to interface
fastethernet | gigabitethernet in the ArubaOS Command-Line Interface Reference Guide.
(host)(config) #interface gigabitethernet <slot>/<module>/<port>
(host)(config-if) #lldp
fast-transmit-counter <1-8>
fast-transmit-interval <1-3600>

Configuring LLDP-MED
Creating an LLDP MED network policy profile does not apply the configuration to any AP or AP interface or
interface group. To apply the LLDP-MED network policy profile, you must associate it to an LLDP profile, then
apply that LLDP profile to an AP wired port profile.
The following commands create a LLDP MED network policy profile for streaming video applications and marks
streaming video as high-priority traffic.
(host) (config) ap lldp med-network-policy-profile vid-stream
(host) (AP LLDP-MED Network Policy Profile "vid-stream") dscp 48
(host) (AP LLDP-MED Network Policy Profile "vid-stream")l2-priority 6
