This is a short text description of the most recent asynchronous workflow (finite state machine, or FSM) that Cisco UCS Manager ran against one external endpoint connection managed under the extpol framework. On cucsExtpolEpFsmDescr, this description is what an admin reads first in the fault/event log to understand, in plain terms, what UCS Manager was last trying to do to this specific endpoint object — for example negotiating or re-establishing its connection. For example, this might read 'Establishing external policy connection' or 'Re-validating registration' for this specific object.
