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.
