LLDP/LLDP-MED will advertise DSCP, VLAN and Priority from an untagged access port, but
the VLAN and Priority values are only provided for informational purposes, since the end device
is sending untagged frames and as such, will only be able to make use of the DSCP information.
It is important that the static priority value configured at the interface port lines up with priority
settings advertised to other voice devices that are LLDP aware in order to have a common QoS
policy throughout the network.
Ensure that LLDP is enabled
By default, LLDP and LLDP-MED will be enabled when using HP Procurve switches.
There are a number of individual settings to enable or disable LLDP or LLDP-MED. More
detailed instructions can be found within the ProCurve switch installation and configuration
manual. For this example, the main activity is to ensure that LLDP functionality is operational.
To enable or disable LLDP across the switch use the following:
LLDP-MED for Location Information
The example in this section shows how to determine and set the individual port settings for
location information. This can take different formats depending upon local administration or
regulatory requirements. The example uses the civic address format rather than the coordinate
or number system. The subcategories used are those highlighted in the ProCurve Networking
manual.
Current information can be obtained by the following:
HP ProCurve Switch 5304XL(config)# lldp run (enable)
HP ProCurve Switch 5304XL(config)# no lldp run (disable)
Note: Mitel Phones do not currently support the LLDP-MED location ID feature. Instead,
Mitel Phones use a proprietary implementation to support emergency call service in
conjunction with the Mitel Emergency Response Adviser.
