VLAN COMMANDS
SWITCHPORT
VOICE VLAN PRIORITY
switchport voice vlan priority
Overview Use this command to configure the Layer 2 user priority advertised when the
transmission of LLDP-MED Network Policy TLVs for voice devices is enabled. This is
the priority in the User Priority field of the IEEE 802.1Q VLAN tag, also known as the
Class of Service (CoS), or 802.1p priority. When LLDP-MED capable IP phones
receive this network policy information, they transmit voice data with the specified
priority.
Syntax
switchport voice vlan priority <0-7>
no switchport voice vlan priority
Default By default, the Voice VLAN user priority value is 5.
Mode Interface Configuration
Usage LLDP-MED advertisements including Network Policy TLVs are transmitted via a
port if:
•LLDP is enabled (lldp run command)
• Voice VLAN is configured for the port (switchport voice vlan command)
• The port is configured to transmit LLDP advertisements—enabled by default
(lldp transmit receive command)
• The port is configured to transmit Network Policy TLVs—enabled by default
(lldp med-tlv-select command)
• There is an LLDP-MED device connected to the port.
To set the Voice VLAN tagging to be advertised, use the switchport voice vlan
command.
Example To remove the Voice VLAN, and therefore disable the transmission of LLDP-MED
network policy information for voice devices on port1.0.6, use the following
commands:
awplus# configure terminal
awplus(config)# interface port1.0.6
awplus(config-if)# no switchport voice vlan
