SWITCHPORT VOICE VLAN
Syntax
switchport voice vlan
vid
Parameters
vid
Specifies the ID number (VID) of the VLAN that functions as the
voice VLAN for ports. You can specify only one VID.
Mode
Port Interface mode
Description
Use this command to add a port to a voice VLAN. The VLAN, which must
already exist, is identified by its VID. A port is added as a tagged port to
the designated VLAN. It transmits the VID in the LLDP-MED network
policy TLV to an IP phone, which, in turn, sends its packets using this
VLAN ID.
A port can be a member of just one voice VLAN at a time. A port that is
already a member of a voice VLAN is removed from its current assignment
before it is added to its new assignment.
This command performs these functions:
Adds the designated port to the voice VLAN as a tagged port. The
equivalent commands are “SWITCHPORT MODE TRUNK” on
page 721 and “SWITCHPORT TRUNK ALLOWED VLAN” on
page 723. (The port’s current untagged assignment is not
changed.)
Activates QoS on the switch, if it is not already. The MLS QOS
ENABLE command also activates QoS on the switch. See “MLS
QOS ENABLE” on page 1633.
Configures the port to trust CoS. The equivalent command is “NO
AUTO-QOS VOICE | TRUST” on page 1640.
