From this i take is that you are using the avaya networking gear with
the fcoe protocol enabled, this is a big no-no. you need to disable
ipsec, then enable dns, your connection should come right back

it is not about lops at all, nor is it about looping, its all about the
trees dude, there is a hidder feature called, treehugger protocol. and
this will help prevent looping in the long term, its hidden behind the
power chord, unplug the power cable from your switch, and you will see
it between the three prongs. no that you can see this, test for
excessive looping

if the step above failed, i would take the cable that is plugged into
port 7 of your switch and plug the other end into port 13, it might
help, i would also leave in there for a while, and go grab a cup of coffee
