Manual voice VLAN assignment mode configuration example
Network requirements
As shown in Figure 43
Create VLAN 2 and configure it as a voice VLAN that permits only voice traffic to pass through.
The IP phones send untagged voice traffic. Configure GigabitEthernet 1/0/1 as a hybrid port.
Configure GigabitEthernet 1/0/1 to operate in manual voice VLAN assignment mode. Configure
GigabitEthernet 1/0/1 to allow voice traffic with an OUI address of 0011-2200-0000, a mask of
ffff-ff00-0000, and a description string of test to be forwarded to the voice VLAN.
