Hi, my setup is
vlan 10
vlan 11
Port fa 0/9 and Fa 0/10 connects to Primary Barrcuda LoadBalancer
Port fa 0/11 and fa 0/12 connects to Secondary Barrcuda LoadBalancer
interface fa 0/9
switchport mode access
switchport access vlan 10
interface fa 0/10
switchport mode access
switchport access vlan 10
interface fa 0/11
switchport mode access
switchport access vlan 11
interface fa 0/12
switchport mode access
switchport access vlan 11
I want to configure Link aggregation using LACP on CatOS,
fa 0/13-16 for vlan 10
fa 0/17-20 for vlan 11
How do i ensure no looping occurs.
Solved! Go to Solution.

Hello Saquib,
all ports in slot 1 will use LACP this is a known limitation of CatOS.
LACP is standard based and should be preferred over PAGP
Hope to help

Hello Saquib,
you need to set the use of LACP at linecard level with:
set channelprotocol lacp ?
set channelprotocol lacp x
set vlan 10 x/13-16
set vlan 11 x/17-20
set port channel x/13-16 M
set port channel x/17-20 N
where M and N are integers channel group numbers must be unique and not used already, x is the slot number
Edit:
I did a mistake
the command is different
set port lacp-channel x/13-16 M mode active
set port lacp-channel x/17-20 N mode active
as described in:

set channelprotocol lacp 1 ( 1 is the module numer for ethernet module )
set vlan 10 1/13-16
set vlan 11 1/17-20
set port lacp-channel 1/13-16 1 mode active
set port lacp-channel 1/17-20 1 mode active
is this config correct
05-20-2010 04:47 AM
Hello Saquib,
to build two different groups you need to use two different number like:
set port lacp-channel 1/13-16 1 mode active
set port lacp-channel 1/17-20 2 mode active

Hi Giuseppe, thanks for supporting the post.
I m confused, do I need One Channel-Group or Two for my requirment.
which command will show bandwidth utilization on the EtherChannel and data_transfer on the Ethernetchannel.

Hello Saquib,
>> I m confused, do I need One Channel-Group or Two for my requirment.
you are going to two different devices so you need to use two groups
>> which command will show bandwidth utilization on the EtherChannel and data_transfer on the Ethernetchannel.
to be investigated
Hope to help

Hi Giuseppe
Thank you for replying. Its clear that I need to have two groups.
Once I apply LACP on mod 1 then all interfaces in mod 1 will be LACP ( 48 port 10/100/100 module ) ; or its possible to use some port in future for PAGP
Thanks

Hi,
Check out the belwo linkfor lacp configuration on cat os switches
http://www.cisco.com/en/US/tech/tk389/tk213/technologies_configuration_example09186a0080094470.shtml
and you are configuring etherchannel between load balancers port and switch it will increase the channel pipe between swicthes and load balancer.
Hope to Help !!
