2.5.3 Example for Configuring LLDP on the Network Where Link
Aggregation Is Configured
After LLDP is configured on the interfaces of network devices, the NMS can obtain the network
topology. The following example describes how to configure LLDP on the network where link
aggregation is configured.
Networking Requirements
As shown in Figure 2-9, SwitchA and SwitchB need to be connected by an Eth-Trunk. The
NMS needs to obtain the Layer 2 information between the Switches. By using the Layer 2
information, a network administrator can know the detailed topology information and
configuration errors on the devices outside the unknown network. These requirements can be
met by configuring LLDP on SwitchA and SwitchB.
The NMS has reachable routes to SwitchA and SwitchB and SNMP parameters are set on all
devices.

Configuration Roadmap
The configuration roadmap is as follows:
1. Add the physical interfaces of SwitchA and SwitchB to the Eth-Trunk.
2. Enable global LLDP on SwitchA and SwitchB.
