Port config

[James Hoggard]

Hello,

I have noticed on allot of our switches we use the following commands under the interface

int gigabitethernet0/1

spanning-tree bpdufilter enable

spanning-tree bpduguard enable

storm-control broadcast level 10.00

when reading on the first command I see this disables spanning tree then the one below protects against it. why have both commands on the same interface in fact why even use bpdufilter if it disables spanning tree and could cause loops?

also storm-control will this put the port into error disable if it see more than 10% broadcast traffic? is this good for end user host or just used for connecting to another switch.

 Thanks.

Because some people don't know the implications when you mix both commands together.  You'd might want to check any STP/BPDU commands set globally.
