3.8.5 (Optional) Configuring an 802.1p Priority and a DSCP Value
for the Voice VLAN
Different 802.1p priorities and DiffServ Code Point (DSCP) values can be configured for
different voice VLANs, which makes voice service deployment more flexible.
Context
By default, the 802.1p priority and DSCP value for each voice VLAN are 6 and 46 respectively.
Manual configuration of the 802.1p priority and DSCP value will allow you to plan priorities
for different voice services at will.
NOTE
l The 802.1p priority is indicated by the value in the 3-bit PRI field in each 802.1Q VLAN frame. This
field determines the transmission priority for data packets when a switching device is congested.
l The DSCP value is indicated by the 6 bits in the Type of Service (ToS) field in the IPv4 packet header.
DSCP, as the signaling for DiffServ, is used for QoS guarantee on IP networks. The traffic controller
on the network gateway takes actions merely based on the information carried by the 6 bits.
Procedure
Step 1 Run:

The system view is displayed.
Step 2 Run:
voice-vlan remark { 8021p 8021p-value | dscp dscp-value }
*
An 802.1p priority and a DSCP value are configured for a voice VLAN.
By default, the 802.1p priority and DSCP value for a voice VLAN are 6 and 46 respectively.
----End
3.8.6 (Optional) Configuring the Mode in Which Ports Are Added
to a Voice VLAN
On a switching device, only one VLAN on a port can be configured as a voice VLAN. Ports can
be added to the voice VLAN in either automatic or manual mode.
