CDP-compatible LLDP configuration example
Network requirements
As shown in Figure 57 , GigabitEthernet 1/0/1 and GigabitEthernet 1/0/2 of Switch A are each
connected to a Cisco IP phone. The two IP phones send out tagged voice traffic.
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 to the voice VLAN to
isolate the voice traffic from other types of traffic.

Configuration procedure
1. Configure a voice VLAN on Switch A:
# Create VLAN 2.
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:
# Enable LLDP globally and enable LLDP to be compatible with CDP globally.
[SwitchA] lldp enable
[SwitchA] lldp compliance cdp
# Enable LLDP on GigabitEthernet 1/0/1 and GigabitEthernet 1/0/2. (You can skip this step
because LLDP is enabled on ports by default.) Configure LLDP to operate in TxRx mode, and
configure CDP-compatible LLDP to operate in TxRx mode on GigabitEthernet 1/0/1 and
GigabitEthernet 1/0/2.
[SwitchA] interface gigabitethernet 1/0/1
[SwitchA-GigabitEthernet1/0/1] lldp enable
[SwitchA-GigabitEthernet1/0/1] lldp admin-status txrx
[SwitchA-GigabitEthernet1/0/1] lldp compliance admin-status cdp txrx
[SwitchA-GigabitEthernet1/0/1] quit
[SwitchA] interface gigabitethernet 1/0/2
[SwitchA-GigabitEthernet1/0/2] lldp enable
[SwitchA-GigabitEthernet1/0/2] lldp admin-status txrx
