IETF MIB Support
In addition to its proprietary features, the TRMMIM currently supports the
following IETF MIBs:
• RFC 1213 MIB for Network Management of TCP/IP-based Internets: MIB-II
• RFC 1271 Remote Network Monitoring MIB
• RFC 1757 Token Ring Extensions to RMON
TRMMIM MIB Structure
Cabletron’s newer intelligent devices — like the TRMMIM — organize MIB data
into a series of “components.” A MIB component is a logical grouping of MIB
data, and each group controls a defined set of objects. For example, for each ring
that is formed in the MMAC chassis, there will be an individual network
component that contains all management information specific to that particular
ring.
The TRMMIM MIB consists of six component groups, each of which is described
below. Note, however, that at any given time, the MIB component list displayed
by your TRMMIM may not include some of the components described below,
since the TRMMIM has the ability to alter the components which make up its MIB
in response to changes in the chassis. For example, if you have two rings formed
in the hub, you will see two “Network” components; if at any time you form a
third logical ring, the necessary MIB component will automatically appear in the
chCompTable. To see which MIB components are currently being used in your
TRMMIM, bring up the Community Names application, or use any SNMP Get
operation that will allow you to view the contents of the chCompTable.
