# LLDP Topology Setup

All documented LLDP configurations are based on the following topology.

## LLDP Topology

**Switch A**:

- Create the interface P1 and make it operationally UP
- Assign the MAC (Media Access Control) Address : 00:01:02:03:04:01
- Assign the Default VLAN (Virtual Local Area Network) IP (Internet Protocol) address: 12.0.0.1

**Switch B**:

- Create the interface P1 and make it operationally UP
- Assign the MAC Address: 00:02:02:03:04:01
- Assign the Default VLAN IP address: 12.0.0.2

LLDP configurations are common for single and multiple instances.

#### Multiple Instance

In the event that a Multiple Instance configuration is required, enable all interfaces and map them to their corresponding switch (virtual instance). The port must be mapped to a switch prior to performing any configurations for LLDP on that port.

Execute the following commands for creating a switch and mapping to an interface:

**To create a Switch**

```
your product# configure terminal
your product(config)# switch default
your product(config-switch)# exit
```

**To create the interface and map it to the Switch**

```
your product(config)# interface gigabitethernet 0/1
your product(config-if)# no shutdown
your product(config-if)# map switch default
your product(config-if)# end
```
