I’m not sure if I’m doing something wrong, or misunderstanding capabilities.
I have two x 3850. I configured one by itself as a core switch, got it all working the way I wanted it.
I connected the second switch with the stackwise cable, watched it join the stack. All good. I can see if I “lose power” to a switch, then the second one takes over as active.
however, I think my misunderstanding comes in here.
I wanted to have a “downstream” switch connected from GI1 to GI1/0/1.
Then have the same downstream switch connected from GI2 to GI/0/1
both configured exactly the same. so if the active switch fails, the passive should bring everything up
actually.. in the process of writing, I think I know what I did wrong.
I need to configure the Gi1 and Gi2 on the downstream switch in a port-group.
then configure GI1/0/1 and GI2/0/1 to be the other end of the port-group.
Correct ? failure of either GI1/01 or 2/0/1 would mean the other interface should start working.. ?
