I do not perceive what’s going on with a change I simply bought. Sorry I solely have a rudimentary information.
I at the moment I’ve two switches N3048 core change which is appearing as the basis (spanning-tree precedence 4096) and an N2048 entry change (spanning-tree precedence 8192)
I added a further entry change N2024 (spanning-tree precedence 61440) in step with the opposite entry change and it retains considering it’s the root and it may well’t talk with the opposite gadgets on the community. I’m at the moment related to it by way of a serial connection, immediately.
That is how the connections look N3048 <-> N2048 <-> N2024, single connections between every. All are working the identical firmware.
I can present configs, however I used to be beneath the impression that so long as the core change had the very best precedence (lowest quantity) and the third change had the bottom precedence (highest quantity) then the basis change would at all times be, on this case, the core change.
What am I lacking?
Thanks in your help.
Okay, right here goes. Right here is the partial config and the related ports from the core change:
