 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

only if there are branches
