TCP/IP MIB-II
ctCpFunction {ctCpEntry 2}
DESCRIPTION
This defines the Com Port Function supported by that Com Port.
SYNTAX INTEGER {lm(1), ups(2), slip(3), ppp(4)}
ACCESS read-write
STATUS mandatory
OBJECT IDENTIFIER: 1.3.6.1.4.1.52.4.3.3.4.1.1.2
The OID will actually be 1.3.6.1.4.1.52.4.3.3.4.1.1.2.1 because there
is only one UART port. We support LM and PPP simultaneously. If
we detect a PPP packet we do negotiations and enter into PPP
mode. As long as PPP keeps live messages we’ll stay there. If they
don’t we revert back to VT100 emulation. We will sample the port
at the time the request comes in and return a value of LM (1), or
PPP (4) depending on what state the port is in at the time of the
request.
ctIfNum {ctCpEntry 3}
DESCRIPTION
This defines the interface that is being described. This is the same
as ifIndex. This is only valid if ctCpFunction is PPP, otherwise 0.
SYNTAX INTEGER
ACCESS read-only
STATUS mandatory
OBJECT IDENTIFIER: 1.3.6.1.4.1.52.4.3.3.4.1.1.3
The OID will actually be 1.3.6.1.4.1.52.4.3.3.4.1.1.3.1 because we
only have the one UART port. We will return our port number for
the UART port.
