Background Information
The Secure Copy Protocol (SCP) is the protocol used for communication from switch processors (SPs) to
non−Distributed Forwarding Card (non−DFC) line cards through the Ethernet out of band channel (EOBC) on
the Catalyst 6500. SCP or keep−alive polling failures might represent communication issues between the
supervisor and the line card.
