# Etherchannel Layer 3 LACP Configuration

#### In this guide, we will cover how to configure LACP for a Layer 3 Etherchannel on Cisco Catalyst switches.

`SW1(config)#interface range eth0/0 - 1` # This command will put you into the interface subconfiguration mode for multiple interfaces

`SW1(config-if-range)#channel-group 44 mode active` # This command will bundle the member interfaces into a port-channel using LACP negotiation to negotiate with the other side actively.

`SW1(config-if-range)#no switchport` # This command turns off the Layer 2 functionality of a switchport and turns it into a Layer 3 routed port

#### - Now we will go into our port-channel configure an IP address

`SW1(config)#interface po44` # This command will put us into the port-channel sub-configuration mode

`SW1(config-if)#ip address [IPv4 address] [Subnet_Mask]` # This command will configure an IP address for the interface

#### - The complete configuration for both switches is shown below

## Verification

#### - The following show commands will verify if the Etherchannel is working properly.

`SW1#show etherchannel summary` # This command will show us if our Etherchannel is bundled and active.
