Example for Configuring LLDP on a Device that Has a Single Neighbor
Networking Requirements
As shown in Figure 6-7, RouterA and RouterB are directly connected; RouterA and ME are directly connected. The NMS has reachable routes to RouterA and RouterB, and SNMP configuration has been complete.
A network administrator wants to use the NMS to obtain communication information between RouterA and ME, and between RouterA and RouterB, as well as the traps about function changes on RouterA and RouterB. According to the preceding information, network administrator can know the detailed network topology and whether configuration conflicts exist on the network.
Configuration Roadmap
The LLDP function
can meet the network administrator's requirement. The configuration
roadmap is as follows:
- Enable global LLDP on RouterA and RouterB.
- Configure management IP addresses for RouterA and RouterB.
- Enable the LLDP trap function on RouterA and RouterB so that trap messages can be sent to the NMS in a timely manner.
Procedure
- Enable global LLDP on RouterA and RouterB.
# Configure RouterA.
<Huawei> system-view [Huawei] sysname RouterA [RouterA] lldp enable
# Configure RouterB.<Huawei> system-view [Huawei] sysname RouterB [RouterB] lldp enable
- Configure management IP addresses for RouterA and RouterB.
# Configure RouterA.
[RouterA] lldp management-address 10.10.10.1
# Configure RouterB.[RouterB] lldp management-address 10.10.10.2
- Enable the LLDP trap function on RouterA and RouterB.
# Configure RouterA.
[RouterA] snmp-agent trap enable feature-name lldptrap
# Configure RouterB.[RouterB] snmp-agent trap enable feature-name lldptrap
- Verify the configurations.
Check RouterA.
# Check the RouterA configuration.
