Once a port goes into a suspended state due to a configuration mismatch, I don't believe it will try to recover on its own (kind of like errdisable). It is possible a mismatch was detected when you were still setting things up, try a shut/no shut on Te1/0/11 and see what happens. If it goes right back to a suspended state, do a show log which should have an error message showing the suspension reason.
