Network requirements
As shown in Figure 58:
GigabitEthernet 1/0/1 and GigabitEthernet 1/0/2 of Switch A are each connected to a Cisco IP
phone.
Configure voice VLAN 2 on Switch A. Enable CDP compatibility of LLDP on Switch A to allow the
Cisco IP phones to automatically configure the voice VLAN, confining their voice traffic within the
voice VLAN and isolating the voice traffic from other types of traffic.
