LLDP and LLDP-MED Configuration Examples
321
The information to be advertised can come from a number of sources, but follows the general
flow outlined below:
• Defaults for LLDP-MED for voice at the Access Port are: Priority = 6; DSCP = 46.
Defaults are overwritten with other information, if available and configured.
• The lowest value voice VLAN ID that is enabled at the port will be used. If a voice VLAN is
not identified, LLDP-MED will not be advertised.
• If the voice VLAN is assigned as "untagged", then the default priority is sent over
LLDP-MED. The DSCP information also uses the default value.
• If the voice VLAN is identified as "tagged" then the QoS settings can come from one of the
following locations:
- ·through Policy Enforcement of a VLAN QoS Priority setting that applies to the
particular voice VLAN. The DSCP information will come from the default.
- ·through Policy Enforcement of a VLAN QoS DSCP setting that applies to the
particular voice VLAN. This also uses the DSCP Map to obtain Priority information, if
available.
The information in the remaining parts of this appendix provide more details on a number of
different network switch parameters that can be used to configure and adjust LLDP-MED values
for more custom operation.
Quick Start – Getting LLDP-MED Running Quickly
To get LLDP-MED working quickly, all that is required is to identify the appropriate VLAN with
the "voice" services as part of the normal switch configuration procedures. The example, below
uses VLAN 63, but this can be replaced with any valid VLAN ID value.
By default, LLDP and LLDP-MED are enabled, and default Priority and DSCP values are already
defined for voice services. All that is required is to identify the voice VLAN with "voice" service
and enable this at the required port.
LLDP-MED for Network Policy Information (VLAN & QoS)
For MiVoice IP Phones to be fully operational for QoS, three network policy parameters need
to be configured. These are:
•VLAN ID
• Layer 2 Priority (IEEE 802.1p) (CoS)
• DSCP (Diff Serv Code Point)
This information can be learned from LLDP-MED compliant network switches.
