This MIB specifies the voice VLAN ID (VVID) to which this interface belongs:
•
0—CDP packets transmitting through this interface will contain Appliance
VLAN-ID TLV with the value of 0. VoIP and related packets are expected to
be sent and received with the value of 0 (VLAN ID=0) and a 802.1p priority.
•
1 to 4094—CDP packets transmitting through this interface will contain
Appliance VLAN-ID TLV with N. VoIP and related packets are expected to
be sent and received with the value of N (VLAN ID=N) and a 802.1p priority.
•
4095—CDP packets transmitting through this interface will contain
Appliance VLAN-ID TLV with the value of 4095. VoIP and related packets
are expected to be sent and received untagged without a 802.1p priority.
•

Appliance VLAN-ID TLV. If the VVID is not supported on the interface, this
