A MIB is a structured set of data that describes the way that the network
is functioning. The management software, known as the agent, gains
access to this set of data and extracts the information it needs. The agent
can also store data in the MIB.
The organization of a MIB allows a network management package based
on the Simple Network Management Protocol (SNMP), such as the
Transcend Enterprise Manager application suite, to manage a network
device without having a specific description of that device. 3Com ships
SNMP MIB files with CoreBuilder 2500 Extended Switching System
software as ASN.1 files.
The data in the MIB consists of objects that represent features of the
equipment that an agent can control and manage. Examples of objects in
the MIB include a port that you can enable or disable and a counter that
you can read.
