Link Group with Subinterfaces

mR00t_s5 — Fri, 20 Oct 2023 14:34:06 GMT

Dear all,
I'm trying to set up our link monitor configuration in our 440, and I ran into a problem. Each of our physical interfaces has many subinterfaces and I only want to monitor a few of those, but when I want to form a new Link Group it doesn't allow for subinterfaces to be chosen, just physical interfaces.
Is there a way in which I can form a new link group with subinterfaces? Thanks!

@mR00t_s5,

You can't use subinterfaces in a link group. Sounds like you may want to look into path monitoring instead of link monitoring.

Yes, that's what I've been reading about, I just wanted to be sure about this first. Thanks!

Sorry I forgot to ask in the post (maybe I'll make another entry) If I set up a Link monitor for a physical Interface with many subinterfaces, and only one of those subinterfaces fails, does it trigger a failover? Or do all of them have to fail for that to happen? Thanks again!
