SNMP MIB ObjectsE-2 3160-A2-GB21-80March 1999MIB II (RFC 1213)The objects defined by MIB II are organized into 10 different groups. TheDSU/CSU implements only those groups where the semantics of the group areapplicable to the implementation of a DSU/CSU. The MIB II object groupssupported or not supported by the 3100 Series devices are as follows:SystemGroupSupported.InterfaceGroupSupported 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.AddressTranslationGroupNot 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 theDSU/CSU.Transmission GroupSupported on the T1 interfaces using the DS1/E1 MIB.Supported on the synchronous data ports using theRS-232-like MIB. Supported on the COM, AUX, and MODEMports using the RS-232-like MIB.SNMP Group Supported.System Group, MIB IIThe System Group objects are fully supported by the DSU/CSU. The followingsections provide clarification for objects contained in the System Group where itis not otherwise clear how the object definition in MIB II is related to theDSU/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 systemhardware and software. This object displays the following string:[Company Name] T1 DSU/CSU; modelxxxx-xx-xxx; S/W Release:yy.yy.yy; H/WCCA1: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.
