CSCtt24735: Editing a port profile fails with the error message “ERROR: unknown error.”
plz Rate if it helped.
Thank you - that is where the bug is listed in the release notes, as I described. I am looking for the detailed bug listing that goes into detail about the bug.
Is the bug details is not seen on CCO, then it is likely internal one. I suggest opening a service request with Cisco to have TAC engineer either disclosed it to you or made external.
