I used to use this defualt configuation for my user access-ports.
spanning-tree portfast
spanning-tree bgpuguard enabe
switch mode acc
This was effective because we had Server admins who liked to set up labs
in their office. Some SOHO switches use a default spanning-tree priority
of 0 or 1. This makes them the root bridge if you don't take measures to
protect your network. I had a lot of problems with slow network response
times until I took care of the spanning-tree issues. The last think you
want to do is have your server farm traffic piped into a 4 port "gum ball
machine" class switch.
As far as the recovery interval. I would use that command in the IDFs but
not in the MDF. If some Exchange Admin decides to boot a netgear switch
in the server farm, i think it should be brought to the attention of
other interested parties who share the facilities.

Subject: BPDU Guard best practice
Date: Thu, 24 May 2007 04:02:44 -0400
Hello,
One of my clients configures BPDU Guard per default on all switch
access ports.
Switch(config-if)# spanning-tree bpduguard enable
The reason for this is that they want to stop STP loop problems as a
result of incorrectly patched access cables.
I'm wondering if this (default config) is a good idea, or if there
are situations that it could give you problems ?
They also use errdisable to automatically recover a port after 10
minutes.
Switch(config)# errdisable recovery interval 600
Switch(config)# errdisable recovery cause bpduguard
Any experience or feedback would be appreciated,
Thanks, Thomas
