- Run:
system-viewThe system view is displayed.
- Run:
interface interface-type interface-number
The interface view is displayed.
- Run:
voice-vlan vlan-id enable [ include-untagged | include-tag0 ]*
A voice VLAN is configured and the voice VLAN function is enabled on the interface.
By default, the voice VLAN function is disabled on an interface.
VLAN 1 cannot be configured as a voice VLAN.
To transmit different services, ensure that the voice VLAN and default VLAN on an interface are different VLANs.
Only one voice VLAN on an interface can be configured as a voice VLAN at a time.
After a voice VLAN is configured on an interface, VLAN mapping, VLAN stacking, or traffic policies cannot be configured on the interface.
- When IP phones send packets tagged with VLAN 0, include-tag0 must be specified on interfaces of X series cards. On other models, include-untagged takes effect for untagged packets and packets tagged with VLAN 0.
