Setting the errdisable timeout function
Does anyone know is the errdisable timeout function is set?
From the STP best practices guide:
BPDU Guard — PortFast moves an end-user port to forwarding state without going through all of the STP checks and can induce loops in the network. If any BPDU is received on a port where BPDU guard is enabled that port is put into errdisable state. It can then be recovered manually or through the errdisable timeout function. Spanning Tree BPDU Guard is used to disable the port in case a new device tries to enter the already existing topology of STP. Thus devices, which were originally not a part of STP, are not allowed to influence the STP topology.
I could not find this in the CLI manual. I am using 55xx and 35xx series switches.

In doing some research on your question, I found that the errdisable timeout feature is not something incorporated in the PowerConnect switches. And once a port is disabled, you must manually enable the port again. I apologize for our guide being incorrect, and I will put in a request to have it changed to reflect the correct information.
Thanks.
