Keyword

 

Action

 

 

 

dot1p

 

Specify that the phone sends the packets with 802.1p priority 5.

 

 

 

untagged

 

Specify that the phone sends the untagged packets.

 

 

 

none

 

Specify that the switch does not send any auxiliary VLAN information in the

 

 

CDP packets from that port.

 

 

 

Verifying the Auxiliary VLAN Configuration

To verify the auxiliary VLAN configuration status, perform this task in privileged mode:

Task

Command

 

 

Verify the auxiliary VLAN configuration status.

show port auxiliaryvlan {vlan untagged

 

dot1p none}

 

 

This example shows how to verify the auxiliary VLAN configuration status:

Console> show port auxiliaryvlan 123

Disabling the Auxiliary VLANs Until an IP Phone is Detected

With software release 8.3(1) and later releases, this feature provides security for the auxiliary VLANs by ensuring that the auxiliary VLAN is not enabled until an IP phone is detected. As soon the switch detects the presence of an IP phone, the auxiliary VLAN is enabled.

The presence of an IP phone is determined through the CDP packet exchange between the switch and the phone. This detection method is used for both the inline-powered and wall-powered IP phones.

Note If the auxiliary VLAN ID equals the port-VLAN ID or when the auxiliary VLAN ID is configured as none, dot1p, or untagged, this feature cannot be applied to the port. If any command entry results in the auxiliary VLAN ID equaling the port-VLAN ID, the feature is disabled and the following warning message is displayed: “cdpverify feature on port <mod>/<port> is disabled.”

To enable or disable the auxiliary VLAN IP phone detection, perform this task in privileged mode (the default is disabled):

Task

Command

 

 

Enable or disable the auxiliary VLAN IP phone

set port auxiliaryvlan mod[/port] {vlan untagged

detection.
