SNMP MIB Objects
E-2 3160-A2-GB21-80March 1999
MIB II (RFC 1213)
The objects defined by MIB II are organized into 10 different groups. The
DSU/CSU implements only those groups where the semantics of the group are
applicable to the implementation of a DSU/CSU. The MIB II object groups
supported or not supported by the 3100 Series devices are as follows:
System
Group Supported.
Interface
Group Supported for the network interface, the DTE Drop/Insert
(DSX-1) interface, the synchronous data ports, the COM port,
the AUX port, and the MODEM port. Interface statistics
(counters) apply to any port (COM, AUX, or MODEM),
whichever is defined as the SNMP management link.
Address
Translation
Group
Not supported since this group is not supported in MIB II.
IP Group Supported.
ICMP Group Supported.
TCP Group Supported.
UDP Group Supported.
EGP Group Not supported since the EGP protocol is not supported by the
DSU/CSU.
Transmissio
n Group Supported on the T1 interfaces using the DS1/E1 MIB.
Supported on the synchronous data ports using the
RS-232-like MIB. Supported on the COM, AUX, and MODEM
ports using the RS-232-like MIB.
SNMP Group Supported.

System Group, MIB II

The System Group objects are fully supported by the DSU/CSU. The following
sections provide clarification for objects contained in the System Group where it
is not otherwise clear how the object definition in MIB II is related to the
DSU/CSU. Objects not mentioned are supported as stated in the MIB.
System Group – “sysDescr” Object (system 1)
This object provides the full name and version identification for the system
hardware and software. This object displays the following string:
[
Company Name
] T1 DSU/CSU; model
xxxx-xx-xxx
; S/W Release:
yy.yy.yy
; H/W
CCA1:
zzzz-zzz;
H/W CCA2:
zzzz-zzz
; Serial number:
ssssssss.
Where: xxxx-xx-xxx
represents the full model number of the unit.
yy.yy.yy
represents the software revision number of the unit.
zzzz-zzz
represents the hardware revision number of the unit.
ssssssss
represents the serial number of the unit.
