Configuring the Auxiliary VLANs on Catalyst LAN Switches

These sections describe how to configure auxiliary VLANs:

•Understanding the Auxiliary VLANs, page 55-20

•Auxiliary VLAN Configuration Guidelines, page 55-21

•Configuring the Auxiliary VLANs, page 55-21

•Verifying the Auxiliary VLAN Configuration, page 55-22

•Disabling the Auxiliary VLANs Until an IP Phone is Detected, page 55-22

Understanding the Auxiliary VLANs

You can configure the switch ports to send CDP packets that instruct an attached Cisco IP Phone 7960 to transmit the voice traffic to the switch in these frame types:

•802.1Q frames carrying the auxiliary VLAN ID and Layer 2 CoS set to 5 (the switch port drops all 802.1Q frames except those carrying the auxiliary VLAN ID).

–Reset the Cisco IP Phone 7960 if the auxiliary VLAN ID changes.

–Enter the set port auxiliaryvlan mod[/port] aux_vlan_id command.

Note We recommend that you use 802.1Q frames and a separate VLAN.

•802.1p frames, which are 802.1Q frames carrying VLAN ID 0 and Layer 2 CoS set to 5 (enter the set port auxiliaryvlan mod[/port] dot1p command).

•802.3 frames, which are untagged and carry no VLAN ID and no Layer 2 CoS value (enter the set port auxiliaryvlan mod[/port] untagged command).

Note The Cisco IP Phone 7960 always sets the Layer 3 IP precedence to 5 in the voice traffic.
