TRMMIM MIB Structure

The TRMMIM MIB consists of the following components:

Chassis MGR

The Chassis MGR MIB component contains most of the basic information about the TRMMIM, the chassis it is controlling, and the other modules installed in that chassis, including: chassis type, backplane type, number of slots, which module types and names are installed in which slots, the TRMMIM’s MIB component information (in the chCompTable), device and module names, hardware revision numbers, MAC and IP addresses, the current time and date, and information related to alarms, ring security, and TFTP download. The following groups from MIB-II are also included: system, interfaces, at, ip, icmp, udp, and snmp. The community names assigned to this MIB component provide the gateway that all SPMA applications use to access all information in the other components, even if those components have different community names; the Chassis MGR community names are the same as those assigned via Local Management.

LM

The TRMMIM LM, or Local Management, component contains the objects that provide out-of-band management via the Console port on the TRMMIM’s front panel. No objects from this component are used for remote management.

Protocol Stack

The Protocol Stack MIB component is the IP stack for in-band communication which provides the TRMMIM with its IP functionality.

SNMP Agent

The SNMP agent MIB component contains the objects that provide the TRMMIM with its IP functionality - essentially, those functions which allow the device to operate over a network - including functions such as ping, Telnet, and TFTP.

Network One, Network Two

The Network MIB components contain all of the objects related to basic Token Ring operation, including ring name, port counts, port enable and disable, ring state, ring speed, active monitor, information about each station inserted on the ring, error status, and packet, byte, and error counts. Also included are the objects related to the alarms function. The default community names for the Network MIB components will always be different from one another and from the default names assigned to all the other components; if you change community names, remember that no network component may ever share a community name with any other network component on the same device.

Note that the only fully implemented Network MIB component will be Network 1 - the one that applies to the ring of which the management device is a part. Each additional Network component - indexed 2, 3, 4, etc. - supplies only minimal, physical management for each independent ring installed in the same chassis.
