Management Information Base (MIB)

B-9

The CoreBuilder system associates statistics with individual ports and then takes action based on these statistics. For example, the system can generate a log event and send an RMON trap if errors on a port exceed a user-set threshold.

You must assign an IP address to the CoreBuilder system to manage RMON. See the CoreBuilder 6000 Administration Console User Guide for information on how to assign an IP address.

Figure B-2shows an example of the CoreBuilder RMON implementation.

Management Information Base (MIB)

A MIB is a structured set of data that describes the way 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 Simple Network Management Protocol (SNMP) network management package such as the Transcend Enterprise Manager application suite to manage a network device without a specific description of that device. 3Com ships SNMP MIB files with CoreBuilder Extended Switching System software as ASN.1 files.
