VoIP phone’s query, it sends the voice VLAN ID
in a reply packet back to the VoIP phone. The VoIP phone then
configures itself within the voice VLAN.
As long as the port to which the VoIP phone is connected has a voice VLAN ID, the phone will configure itself into
that voice VLAN. If you change the voice VLAN ID, the software will immediately send the new ID to the VoIP
phone, and the VoIP phone will re-configure itself with the new voice VLAN.
Configuration Notes
•
This feature is supported in software releases 02.2.00 and later for the FESX, FSX, and FWSX devices.
•
This feature works with any VoIP phone that:
•
Runs CDP
•
Sends a VoIP VLAN query message
•
Can configure its voice VLAN after receiving the VoIP VLAN reply
•
Automatic configuration of a VoIP phone will not work if one of the following applies:
•
You do not configure a voice VLAN ID for a port with a VoIP phone
•
You remove the configured voice VLAN ID from a port without configuring a new one
•
You remove the port from the voice VLAN
•
Make sure the port is able to intercept CDP packets (
cdp run
command).
•
Some VoIP phones may require a reboot after configuring or re-configuring a voice VLAN ID. For example, if
your VoIP phone queries for VLAN information only once upon boot up, you must reboot the VoIP phone
before it can accept the VLAN configuration. If your phone is powered by a PoE device, you can reboot the
phone by disabling then re-enabling the port.
Enabling Dynamic Configuration of a Voice over IP (VoIP) phone
You can create a voice VLAN ID for a port, or for a group of ports.
To create a voice VLAN ID for a port, enter commands such as the following:
FESX424 Switch(config)# interface e 2
FESX424 Switch(config-if-e1000-2)# voice-vlan 1001
To create a voice VLAN ID for a group of ports, enter commands such as the following:
FESX424 Switch(config)# interface e 1-8
FESX424 Switch(config-mif-1-8)# voice-vlan 1001
Syntax:
[no] voice-vlan <voice-vlan-num>
where <voice-vlan-num> is a valid VLAN ID between 1 – 4095.
To remove a voice VLAN ID, use the
no
form of the command.
Viewing Voice VLAN Configurations
You can view the configuration of a voice VLAN for a particular port or for all ports.
To view the voice VLAN configuration for a port, use the
show voice-vlan
<port-num> command. The following
example shows the command output results.
FESX424 Switch(config)# show voice-vlan ethernet 2
Voice vlan ID for port 2: 1001
