Basic port parameter configuration

• 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.
Brocade(config)# interface ethernet 2
Brocade(config-if-e1000-2)# voice-vlan 1001
To create a voice VLAN ID for a group of ports, enter commands such as the following.
Brocade(config)# interface ethernet 1-8
Brocade(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, specify the port number with the show voice-vlan
command. The following example shows the command output results.
The following example shows the message that appears when the port does not have a configured
voice VLAN.
To view the voice VLAN for all ports, use the show voice-vlan command. The following example
shows the command output results.
Syntax: show voice-vlan [ethernet port]
Brocade# show voice-vlan ethernet 2
Voice vlan ID for port 2: 1001
Brocade# show voice-vlan ethernet 2
Voice vlan is not configured for port 2.
Brocade# show voice-vlan
