Module: CISCO-STACK-MIB

OID (symbolic): CISCO-STACK-MIB::vlanPortAuxiliaryVlan

Description: The Voice Virtual Vlan ID (VVID) to which this port belongs to. If the VVID is not supported on the port, this MIB object will not be configurable and will return 4096.

Setting this MIB object to 4096, the CDP packets transmitting through this port would not include Appliance VLAN-ID TLV.

Setting this MIB object to 4095, the CDP packets transmitting through this port would contain Appliance VLAN-ID TLV with value of 4095 - VoIP and related packets are expected to be sent and received untagged without an 802.1p priority.

Setting this MIB object to 0, the CDP packets transmitting through this port would contain Appliance VLAN-ID TLV with value of 0 - VoIP and related packets are expected to be sent and received with VLAN-id=0 and an 802.1p priority.

Setting this MIB object to N (1..1000|1025..4094), the CDP packets transmitting through this port would contain Appliance VLAN-ID TLV with N - VoIP and related packets are expected to be sent and received with VLAN-id=N and an 802.1p priority.

This object is deprecated and replaced by vmVoiceVlanId in CISCO-VLAN-MEMBERSHIP-MIB.

What is vlanPortAuxiliaryVlan?
