Not sure about all the other answers i've seen such as "set spantree root"
and how they would accomplish your goal but from what I've read it appears
that Emad is looking to ignore ANY BPDU's. I wouldn't really call a port
going into blocked (root-inconsistent state) as "ignoring" but......
Did you spend the time to look this up?
BPDU Filter will make it not send/receive BPDU's.
Caution Enabling BPDU filtering on an interface is the same as disabling
spanning tree on it and can result in spanning-tree loops.
At the global level, you can enable BPDU filtering on Port Fast-enabled
ports by using the spanning-tree portfast bpdufilter default global
configuration command. This command prevents ports that are in a Port
Fast-operational state from sending or receiving BPDUs
Straight from the 3550 config guide..
Or if your looking just to "guard" against one of your customer's switches
from becoming the root switch in your domain (your topology may vary) you
can look at the "spanning-tree guard root" (interface level command)

Folks,
How can we configure STP on 3550 switch such that it ignores BPDUs from
other root switches
Thanx
