Gigastack module, port configuration

Unanswered Question
Apr 24th, 2007

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,

I have this problem too.
