CDP-Compatible LLDP Configuration Example

Network requirements
As shown in Figure
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, 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
# Create VLAN 2.
<SwitchA> system-view
[SwitchA] vlan 2
[SwitchA-vlan2] quit
# Set the link type of GigabitEthernet 1/0/1 and GigabitEthernet 1/0/2 to trunk and enable voice VLAN
on them.
[SwitchA] interface gigabitethernet 1/0/1
[SwitchA-GigabitEthernet1/0/1] port link-type trunk
[SwitchA-GigabitEthernet1/0/1] voice vlan 2 enable
[SwitchA-GigabitEthernet1/0/1] quit
[SwitchA] interface gigabitethernet 1/0/2
[SwitchA-GigabitEthernet1/0/2] port link-type trunk
[SwitchA-GigabitEthernet1/0/2] voice vlan 2 enable
[SwitchA-GigabitEthernet1/0/2] quit
2) Configure CDP-compatible LLDP on Switch A.
