Configuration procedure
# Create VLAN 2 and VLAN 3.
[DeviceA] vlan 2 to 3
# Set the voice VLAN aging time to 30 minutes.
[DeviceA] voice vlan aging 30
# Since GigabitEthernet 2/0/1 may receive both voice traffic and data traffic at the same time, to ensure
the quality of voice packets and effective bandwidth use, configure voice VLANs to work in security
mode, that is, configure the voice VLANs to transmit only voice packets. (Optional. By default, voice
VLANs work in security mode.)
[DeviceA] voice vlan security enable
# Configure the allowed OUI addresses as MAC addresses prefixed by 0011-1100-0000 or
0011-2200-0000. In this way, Device A identifies packets whose MAC addresses match any of the
configured OUI addresses as voice packets.
[DeviceA] voice vlan mac-address 0011-1100-0001 mask ffff-ff00-0000 description IP phone A
[DeviceA] voice vlan mac-address 0011-2200-0001 mask ffff-ff00-0000 description IP phone B
# Configure GigabitEthernet 2/0/1 as a hybrid port.
[DeviceA] interface gigabitethernet 2/0/1
[DeviceA-GigabitEthernet2/0/1] port link-type hybrid
# Configure GigabitEthernet 2/0/1 to operate in automatic voice VLAN assignment mode. (Optional. By
default, a port operates in automatic voice VLAN assignment mode.)
[DeviceA-GigabitEthernet2/0/1] voice vlan mode auto
# Configure VLAN 2 as the voice VLAN for GigabitEthernet 2/0/1.
[DeviceA-GigabitEthernet2/0/1] voice vlan 2 enable
[DeviceA-GigabitEthernet2/0/1] quit
# Configure GigabitEthernet 2/0/2.
[DeviceA] interface gigabitethernet 2/0/2
