I have an S4 (main campus) with a lag on one end and I have three stacked B5's (remote campus) on the other. They are connected via 1 mile long fiber.
Complaint from end user's has been poor internet speeds at the remote campus. They are on a VLAN and come back via the fiber to go out through our internet provider.
I just started this job and am new to the extreme EOS though I just finished the bootcamp and passed the switching and routing exam.
I started to just look at the VLAN performance and noted it was terrible and I'm on main campus side. I'm trying to document the existing switching design etc. So I began to dig into how things are connected L1/L2.
I did notice though that I have two ports on the S4 setup as a LAG to the stacked B5's but on the stacked B5's there are NO LAGs configured. Globally LACP is enabled on both ends but the stack hasn't been configured with a lag.
So first question is, how does this even work? I thought that you had to have both ends configured properly for the LAG to work. I know they can form automatically due to the global setting but I can't find anything on the B5's to indicate that has occurred.
Should I go ahead and setup the lag properly on each end with aadminkey's which one side appears to have already?
Port status shows the ports on the remote end to both be UP, all of the lag's appear as down this is the same as the main campus.
So it looks to me that the lag's are not configured and up properly and that neither end is setup.
Sorry for the long story but wanted to get some feed back on the situation.
Thoughts and suggestions are appreciated!
