Hello ,
Computer is connected to a Cisco IP Phone. Last week, the port gets err-disabled 4-5 times. Switch logs shows the following.
Oct 13 05:22:58.620 CCT: %SPANTREE-2-BLOCK_BPDUGUARD: Received BPDU on port Fa1/ 0/19 with BPDU Guard enabled. Disabling port. (CN-WUHRC-RCAS04-1)

And only IP phone and PC is connected to this port . And later i tried with a new patch cable and issue got resolved.
Can anybody comment on this ? How physical cable and BPDU are related ?
