Hello,
I am fairly new to this network and am trying to figure the STP topology to find redundant links and whatnot.
We have switches with gigastack adapter in 1 of the two fibre channels (GigabitEthernet 0/1 and 0/2)
when run sh interfaces gigabitethernet0/1
output shows 0/1 is up, media CX, link 1 is up, link 2 is up.
0/2 is true fibre channel
when run sh spanning-tree,
output is, GiGabit 0/1 altrn Block
Gigabit 0/2 Desg
on other switches show
Gig 0/1 root fwd 4
Gig 0/2 Desg
I want to know how to differentiate between which link, link 1 or 2, on the Gigastack is the blocked one. one link goes to other switch, next in line. one link goes to redundant link, (uplink)
any input helps
thanks,
