Error Message
UDLD-4-UDLD_PORT_DISABLED: UDLD disabled interface [chars], [chars]

neighbors that were functioning only in one direction, which might potentially cause spanning-tree
loops or interfere with connectivity. The cause is likely to be hardware related, either due to a bad
port, a bad cable, or a misconfigured cable. The first [chars] is the interface, and the second [chars]
is the error detected.
