We have recently installed Barracuda Load Balancer on the network on a dedicated vlan for loadbalancer.
LB is with 6 Interface and would like to combine these interfaces. LB supports only LACP.
What steps are required to configure LACP on Cisco Switch
Current : Switch_Conf
interface vlan 7
ip address 10.10.10.1 255.255.255.248
interface fa 0/25
description connected to LoadBalancer
switchport mode access
switchport access vlan 7
Int 1.1 : IP 10.10.10.2 255.255.255.248
The command bellow sets a int to lacp active mode. Use it under each interface.
'channel-group 10 mode active'
If the order side has lacp support activated it will form a port-channel 10 interface.
Optionally you can force the etherchannel without depending on the aggregation protocol using
'channel-group 10 mode on'.
To see the statistics about lacp use 'show lacp counters' or 'show lacp neighbor'.
