In the skit, I would like to connect the two Stacked switches with a third one using the SFPs+ Modules and therefore I need to configure the LACP for them.

How can I configure the LACP on both the Third Switch and the Stacked ones?

A stack of 2 switches forms a single logical switch.

So you first configure the stack, without considering the third one.

You now have 2 switches (one stack and one standalone)

Then you create a Ling Aggregation Group (LAG) between the stack and the third switch, with a link from each stack member to the standalone switch.

Note: HP use the term "trunk" for a LAG while usually this term refer to a link carrying several VLAN (and I profoundly hate them for that).

I am no ARUBA expert but from this documentation you configure the interfaces in LACP active mode with the command

switch(config)# int c1-c4 lacp active

The documentation is sparse about it though. Hope some other people can help you with more details about the config.

  • Yes exactly what I want to do, how can I make the LAG between the stack and the third switch, please?

  • @Kikomi You can simply select ports across the stacking group (VSF) as LACP trunk members (e.g. a1,b1-b2). You might also want to consider integrating the 3rd switch into the stack.
