Example for Configuring LLDP on the Device That Has a Single Neighbor
Networking Requirements
As shown in Figure 5-1, SwitchA and SwitchB are directly connected,routes between the NMS and SwitchA, and the NMS and SwitchB are reachable; SNMP is configured.
A network administrator wants to obtain communication information between between SwitchA and SwitchB, and alarms of device function changes to know the detailed network topology and configuration conflicts.
Configuration Roadmap
The LLDP function can meet the network administrator's requirement. The configuration roadmap is as follows:
- Enable global LLDP on SwitchA and SwitchB.
- Configure management IP addresses for SwitchA and SwitchB.
Procedure
- Enable global LLDP on SwitchA and SwitchB.
# Configure SwitchA.
<Quidway> system-view [Quidway] sysname SwitchA [SwitchA] lldp enable
# Configure SwitchB.<Quidway> system-view [Quidway] sysname SwitchB [SwitchB] lldp enable
- Configure management IP addresses for SwitchA and SwitchB.
# Configure SwitchA.
[SwitchA] lldp management-address 10.10.10.1# Configure SwitchB.[SwitchB] lldp management-address 10.10.10.2 - Verify the configurations.
Check neighbor information of SwitchA.
[SwitchA] display lldp neighbor brief Local Intf Neighbor Dev Neighbor Intf Exptime GE0/0/1 SwitchB GE0/0/1 101
Check neighbor information of SwitchB.
[SwitchB] display lldp neighbor brief Local Intf Neighbor Dev Neighbor Intf Exptime GE0/0/1 SwitchA GE0/0/1 101
