Network requirements
As shown in Figure 44:
• The MAC address of IP phone A is 0011-1100-0001. The phone connects to a downstream device
named PC A whose MAC address is 0022-1100-0002, and to GigabitEthernet 4/0/1 on an
upstream device named Router A.
• The MAC address of IP phone B is 0011-2200-0001. The phone connects to a downstream device
named PC B whose MAC address is 0022-2200-0002, and to GigabitEthernet 4/0/2 on Router A.
• Router A uses voice VLAN 2 to transmit voice packets for IP phone A and uses voice VLAN 3 to
transmit voice packets for IP phone B.
Configure GigabitEthernet4/0/1 and GigabitEthernet 4/0/2 to operate in automatic voice VLAN
assignment mode. In addition, if one of them has not received any voice packet in 30 minutes, the port
is automatically removed from the corresponding voice VLAN.
