CDP-Compatible LLDP Configuration Example
Network requirements
As shown in Figure 22-5 :
GigabitEthernet 2/0/1 and GigabitEthernet 2/0/2 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, thus confining their voice traffic within
the voice VLAN to be isolated from other types of traffic.

Configuration procedure
1) Configure a voice VLAN on Switch A
