SNMP MIB Objects
E-17 3162-A2-GB20-30 March 1999
RS-232-like MIB (RFC 1317)
The “rs232” object defined by RFC 1317 is supported for all of the synchronous
data ports, the COM port, and the AUX port. The RS-232-like MIB consists of one
object and five tables, as follows:
H
Number of RS-232-like ports
H
The General Port Table
H The Asynchronous Port Table
H
The Synchronous Port Table
H The Input Signal Table
H
The Output Signal Table
The Asynchronous Port table is not supported by the DSU/CSU for the
synchronous data ports. The Input Signal and Output Signal tables are not
supported for the AUX and COM ports. The following sections provide
clarification for objects contained in the RS-232-like MIB when it is not clear how
the object definition in MIB is related to the DSU/CSU.
Number of Ports – “rs232Number ” Object (rs232 1)
This object contains the number of ports in the RS-232-like general port table.
This number is 4 for the 3162.
General Port Table, RS-232-like MIB
The general port table contains general configuration objects for the RS-232-like
interfaces.
General Port Table – “rs232PortIndex” Object (rs232PortEntry 1)
This object contains a unique value for each port and is used as an index into the
general port table (rs232PortTable). The values of the rs232PortIndex object vary
between models and are listed below.
The values of rs232PortIndex for the 3162 DSU/CSU are:
H
1 – COM port
H 3 – Auxiliary RS-232 port
H
4 – DCE port 1
H 5 – DCE port 2
