LLDP and LLDP-MED Configuration Examples
327
A range of ports would be assigned to a voice VLAN in the following manner:
In this example, ports A1, A3 and a range of B1 to B16 are assigned to the voice VLAN 63.
Note that multiple VLANs can be assigned to be voice VLANs. However, the typical operation
would be to assign a single voice VLAN to a particular port. In the event that multiple voice
VLANs are assigned to a port, then only the lowest value VLAN ID will be advertised by
LLDP-MED.
DEFINING DSCP TO PRIORITY (COS) MAPPING (OPTIONAL)
The DSCP and Layer 2 Priority values, to be advertised by LLDP-MED, may be obtained from
the DSCP to Priority map list. (Where the default LLDP-MED settings are not to be used, then
this is the recommended method, as it allows the voice QoS policy to be defined without the
requirement to apply a general switch Policy Enforcement.)
By default, the Procurve switches will already have a Priority value of 7 applied to the DSCP
Expedited Forwarding (value of 46, or 101110). All that is required is to identify the DSCP 46
as being used for voice policy.
In most network switches a Priority value of 6 or 7 will make little difference, other than to identify
the packet as high priority and higher than standard data. Some administrators prefer to reserve
Priority 7 for network management only, and to use Priority 6 for voice. This example will be
shown. Other values can also be configured if needed depending on installation.
It is important to complete the DSCP to Priority (CoS) mappings before assigning any
Priority/QoS Enforcement policies at the individual port, or across the network switch. Failure
to do this may result in mismatched information and unexpected error conditions.
First, determine the current DSCP mapping.
63 VLAN63 | Port-based Yes
Note: ProCurve switches will only advertise LLDP-MED for ports that are members of
VLANs with the "voice" attribute, as shown above.
