Hello

6506--------------------------Loadbalancer

6506 gi 1/5 connect to loadbalancer giga 0/0

6506 gi 1/6 connect to loadbalancer giga 0/1

6506 is running CATOS

on 6506

vlan 5

description IN_balance

vlan 6

description Out_balance

int giga 1/5

switchport access vlan 5

int giga 1/6

switchport access vlan 6

How do I configure LACP on 6506 running CATOS and aggregate giga 1/7-8 to VLAN 5 && giga1/9-10 to VLAN 6

Hello Saquib,

CatOS is limited to OSI layer 2 operations so you cannot configure a L3 etherchannel on it.

the commands you have found on Reza's link should be enough to setup a L2 etherchannel using LACP.

My only doubt is that you may need to set the LACP system-id as this was a mandatory step in first IOS switches.

Edit:

command for port channel protocol applies to slot numbers = modules not to channel group number, so be aware of this difference

This example shows how to specify the LACP protocol for modules 2 and 3:

Console> (enable) set channelprotocol lacp 2,3

Mod 2 is set to LACP protocol.

Mod 3 is set to LACP protocol.

Console> (enable)

see

http://www.cisco.com/en/US/docs/switches/lan/catalyst6500/catos/7.x/configuration/guide/channel.html#wp1027500

the other commands for setting LACP system-id, LACP port priority are optional

Hope to help

Giuseppe

Hello Reza

Is this the only command needed to configure LACP on catOS switch

set channelprotocol lacp 1

set port lacp-channel 1/1,1/2 mode active


on IOS the config was

Switch(config)# interface port-channel 1

Switch(config-if)# ip address 172.32.52.10 255.255.255.0

Switch(config)# interface range fastethernet 5/4 - 5
Switch(config-if)# no switchport
Switch(config-if)# no ip address
Switch(config-if)# channel-group 1 mode active

Can you help with config steps for LACP L2 Etherchannel and LACP L3 Etherchannel
