I am new to my network and am documenting physical connections and STP paths and noticed that there are different costs between the B5 and E1 products. I have some locations with mixed equipment and have noticed some odd paths due to the cost differences.
For instance my B5 which is one hop from the core and part of a ring of E1's has an alternate port blocking.
So I have an S4 -> B5 -> E1 ->E1 ->E1 ->E1 ->S4
I would have expected the AP to be in the middle of the E1's not at the B5.
Hope that makes some sense.
How do you deal with the cost differences. B5 says 20000, E1 say 1 for a fiber sfp links.
Any thoughts or help would be appreciated thanks!
