F. SNMP MIB Objects
F-2
March 2001 3160-A2-GB24-10
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, 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.
