CCNP Interview Question:

What is error disabled port in switching and what is dynamic desirable mode?

Submitted by: Zak

Error disabled when a port is error disabled, it is effectively shut down and no traffic is sent or received on that port. such as, with BPDUGourd you said this port must not send bpdu or receive it as well .. so when this port receive bpdu message it will convert to error disable .. and to make it up again just write (No Shut) command.
Dynamic Desirable:- it is kind or DTP (dynamic trunk protocol) in short, negotiation with front port to be trunk.
