Mib-Ii - 3Com 4007 Implementation Manual

MIB-II

MIB-II defines various groups of manageable objects that contain device
statistics as well as information about the device, device status, and the
number and status of interfaces.
The MIB-II data is collected from network devices using SNMP. As
collected, this data is in its raw form. To be useful, data must be
interpreted by a management application, such as Status Watch.
MIB-II, the only MIB that has reached Internet Engineering Task Force
(IETF) standard status, is the one MIB that all SNMP agents are likely to
support.
Table 101 lists the MIB-II object groups. The number following each
group indicates the group's branch in the MIB subtree.
MIB-I supports groups 1 through 8; MIB-II supports groups 1 through 8,
plus two additional groups.
