Network requirements
As shown in Figure 10:
• 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 Ethernet 1/1 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 Ethernet 1/2 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 Ethernet 1/1 and Ethernet 1/2 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.
