                    This should be the highest available related MIB,
                    corresponding to charSessProtocol, such as Telnet.
                    For example, the value for a TCP connection (in the
                    absence of a Telnet MIB) is the object identifier of
                    tcpConnState.  If an agent is not configured to have
                    such values, the agent returns the object
                    identifier:

                        nullConnectionId OBJECT IDENTIFIER ::= { 0 0 }
