LACP

Answered Question
Oct 9th, 2009

Hello,

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

vlan 7

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

Load-Balancer-Config

Int 1.1 : IP 10.10.10.2 255.255.255.248

I have this problem too.

Hi,

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'.

Create the port channel interface and do a shut on it . Then with the interface range command add the following to the ports "channel-group 2 mode active" . Then do a no shut on the port channel interface.

interface port channel 2

interface f0/25

channel-group 2 mode active

Hi,

Is it possible to get clue from which interface the traffic is flowing ( sending/receiving)... assuming we have 5 interface in the channel-group2

Use 'show interface etherchannel', see the load parameter.
