Cdp-Compatible Lldp Configuration Example - HP A6600 Configuration Manual

As the sample output shows, GigabitEthernet 4/1/2 of Router A does not connect to any neighboring
devices.

CDP-compatible LLDP configuration example

Network requirements
As shown in
GigabitEthernet 4/1/1 and GigabitEthernet 4/1/2 of Router A are each connected to a Cisco IP
•
phone.
Configure voice VLAN 2 on Router A. Enable CDP compatibility of LLDP on Router A to allow the
•
Cisco IP phones to automatically configure the voice VLAN, confining their voice traffic within the
voice VLAN to be isolated from other types of traffic.

Configuration procedure
Configure a voice VLAN on Router A
1.
# Create VLAN 2.
<RouterA> system-view
[RouterA] vlan 2
[RouterA-vlan2] quit
# Set the link type of GigabitEthernet 4/1/1 and GigabitEthernet 4/1/2 to trunk and enable voice VLAN
on them.
[RouterA] interface gigabitethernet 4/1/1
[RouterA-GigabitEthernet4/1/1] port link-type trunk
[RouterA-GigabitEthernet4/1/1] voice vlan 2 enable
[RouterA-GigabitEthernet4/1/1] quit
[RouterA] interface gigabitethernet 4/1/2
[RouterA-GigabitEthernet4/1/2] port link-type trunk
[RouterA-GigabitEthernet4/1/2] voice vlan 2 enable
[RouterA-GigabitEthernet4/1/2] quit
Configure CDP-compatible LLDP on Router A
2.
# Enable LLDP globally and enable LLDP to be compatible with CDP globally.
[RouterA] lldp enable
[RouterA] lldp compliance cdp
# Enable LLDP (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 4/1/1 and
GigabitEthernet 4/1/2.
[RouterA] interface gigabitethernet 4/1/1
[RouterA-GigabitEthernet4/1/1] lldp enable
[RouterA-GigabitEthernet4/1/1] lldp admin-status txrx
[RouterA-GigabitEthernet4/1/1] lldp compliance admin-status cdp txrx
