Configuration Guidelines; Configuring Dynamic Port Vlan Membership With Auxiliary Vlans - Cisco WS-X6066-SLB-APC - Content Switching Module Software Manual

Chapter 18 Configuring Dynamic Port VLAN Membership with VMPS
Prior to software release 6.2(1), dynamic ports could only belong to one VLAN. You could not enable the
dynamic port VLAN feature on ports that carried a native VLAN and an auxiliary VLAN.
With software release 6.2(1) and later releases, the dynamic ports can belong to two VLANs. The switch
port configured for connecting an IP phone can have separate VLANs configured for carrying:

Configuring Dynamic Port VLAN Membership with Auxiliary VLANs

This example shows how to add voice ports to auxiliary VLANs and specify an encapsulation type:

Data traffic to and from the PC connected to the switch through the access port of the IP phone
(native VLAN)

Configuration of the native VLAN ID is dynamic for the PC connected to the access port of the IP phone.
Configuration of the auxiliary VLAN ID is not dynamic; you need to configure it manually. As the
auxiliary VLAN ID is manually configured, the VMPS server is queried for packets coming from the PC,
not for packets coming from the IP phone.
All packets except Cisco Discovery Protocol (CDP) packets from the IP phone are tagged with the
auxiliary VLAN ID. All packets tagged with the auxiliary VLAN ID are considered to be packets
from the phone and all other packets are considered to be packets from the PC.
When configuring the auxiliary VLAN ID with 802.1p or untagged frames, you need to configure
the VMPS server with the IP phone's MAC address (see the
VMPS Configuration Examples" section on page 18-9
For dynamic ports, the auxiliary VLAN ID cannot be the same as the native VLAN ID assigned by
VMPS for the dynamic port.
See the "Dynamic Port VLAN Membership and VMPS Configuration Guidelines" section on
page 18-3 prior to configuring any port.
