Hi Kitty,

you can preconfigure the stack If you have only 1 active switch, After your port configuration, you just need to connect your pre-configured switch-model.

Please check if your Firewall can handle LACP. Otherwise you need to change the protocol.

interface GigabitEthernet1/0/3
channel-protocol lacp
channel-group 1 mode active
!
interface GigabitEthernet2/0/2
channel-protocol lacp
channel-group 1 mode active
!
interface GigabitEthernet1/0/2
channel-protocol lacp
channel-group 2 mode active
!
interface GigabitEthernet2/0/3
channel-protocol lacp
channel-group 2 mode active

Hello Michel,

Thank you again, after checking your document and I try to draw the network diagram

Please help to configure the Catalyst 3750x Stack to support HA firewall and correct me if something is wrong.

Thank you

Yes of course, you don’t want a single point of failure. I recommend the version “(4)” in this picture: https://en.wikipedia.org/wiki/MC-LAG#/media/File:Using_Multi-Chassis_LAG_(MC-LAG)_for_High_Availability.png

Hello Michel,

Thank you
Could you recommend configure Multi-Chassis Link Aggregation (MLAG) Catalyst 3750x Stack that connect to 2 x Firewall HA ?

Thank you

You have only to configure two ports:

interface FastEthernet1/0/1
channel-protocol lacp
channel-group 1 mode active
!
interface FastEthernet2/0/1
channel-protocol lacp
channel-group 1 mode active
