Hi,
I was looking for some advice to see if it is recommended to configure BPDU Guard on ports connected to IP phones to prevent routing loops?

why u expect routing loop from a port connected to a phone?
anyway u can do it
good luck

My main concern regarding rooting loops is that we have a PC connected to the data port on the phone. I am concerned that if this is invertible connected to another switch (say accidently patched incorrectly) would this cause a loop?

Hi Andy,
I just thought that I would add this link to the good info from my friend Marwan. It's a pretty good read :) (well not not Mark Twain ....but)
Root guard or BPDU guard
Enable root guard or BPDU guard on all access ports to prevent the introduction of a rogue switch
that might attempt to become the Spanning Tree root, thereby causing STP re-convergence events
and potentially interrupting network traffic flows. Ports that are set to errdisable state by BPDU
guard must either be re-enabled manually or the switch must be configured to re-enable ports
automatically from the errdisable state after a configured period of time.
From this CCM SRND doc;
Cisco Unified Communications SRND Based on Cisco Unified CallManager 4.x
Network Infrastructure
Hope this helps!
