The best way for redundancy in a stack

[Mateusz_Haba]

Hi folks,

I'm wondering what's the best/right way of achieveing redunancy using stacked switches.

Let's assume I've got 1 server connected with 2 links to stacked switch - one link goes to Unit1 and second to Unit 2.
Is it better to create a LAG group for these 2 ports or configure port redundancy with

configure ports redundant on

and what are pros/cons of each?

For example, if you have 2 servers - one primary, second - backup.
Or 2 switches, or 2 links to 2 different ISP.

Thank you!

That makes more sense for me now. Thanks!

Hi!

I think that is better - LAG:

• redundancy
• traffic sharing between 2 ports (wider link)
• less latency
• less problems with microburst

Thank you!

So in what case we want to use the second solution?
