Chapter 19 Configuring Dynamic Port VLAN Membership with VMPS
Dynamic Port VLAN Membership with Auxiliary VLANs
• 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 “Dynamic Port VLAN Membership with
VMPS Configuration Examples” section on page 19-10 for information on configuring VMPS).
• For the dynamic ports, the auxiliary VLAN ID cannot be the same as the native VLAN ID that is
assigned by VMPS for the dynamic port.
• See the “Dynamic Port VLAN Membership and VMPS Configuration Guidelines” section on
page 19-3 prior to configuring any port.
Configuring Dynamic Port VLAN Membership with Auxiliary VLANs
To configure dynamic port VLAN membership with auxiliary VLANs, perform this task in privileged
mode:
This example shows how to add voice ports to the auxiliary VLANs and specify an encapsulation type:
Console> (enable) set port auxiliaryvlan 5/9 222
Auxiliaryvlan 222 configuration successful.
AuxiliaryVlan AuxVlanStatus Mod/Ports
------------- ------------- -------------------------
222 active 5/9
Console> (enable)
Console> (enable) set port auxiliaryvlan 5/9 dot1p
Port 5/9 allows the connected device send and receive packets with 802.1p priority.
Console> (enable)
This example shows how to specify port 5/9 as a dynamic port:
Console> (enable) set port membership 5/9 dynamic
Warning: Auxiliary Vlan set to dot1p|untagged on dynamic port. VMPS will be queried for IP
phones.
Port 5/9 vlan assignment set to dynamic.
Spantree port fast start option enabled for ports 5/9.
Console> (enable)
This example shows that the auxiliary VLAN ID specified cannot be the same as the native VLAN ID:
Console> (enable) set port auxiliaryvlan 5/10 223
Auxiliary vlan cannot be set to 223 as PVID=223.
Console> (enable)
Task Command
Configure dynamic port VLAN
membership with the auxiliary VLANs.
set port auxiliaryvlan mod[/port] {vlan | untagged |
dot1p | none} [cdpverify {enable | disable}]
