shut/no shut on the interface that is causing problems. This is the only way if you have a loop to stop it immediately.

Apologies, didn't realise you wanted to automate it.
Flooding and loops are slightly different. For loop avoidance you want to be looking at BPDUGuard and BPDUFilter -
for flooding you should look at storm control -

Dear Jon,
Now i have one query,
I have 3550 48P switch in this switch interface port frpm int 3 to 48 connected with IP DSLAM. this means many users conneted with one interface in cisco 3550 , that's why i dint configure spanning-tree port fast enable it is disable on per interface,
so now should configure on per port ( port 3 to 48) BPDU filter or BPDU guard ?? or both the command to give on interface ?? global mode ?? which one!!
at present in cisco 3550 i have configured in global mode spanning-tree mode pvst and on per interface i have configuered spanning-tree portfast disable.
so now should i configue on per interface spanning-tree bpdufilter enable and also spanning-tree bpdguard enable when spanning-tree portfast disable ???
What you suggest me what i hve to do ??
Thanks once again!!!
