As the sample output shows, GigabitEthernet 1/0/2 of Switch A does not connect to any neighboring
devices.
CDP-compatible LLDP configuration example
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.

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
# Enable LLDP globally and enable LLDP to be compatible with CDP globally.
