TRMMIM MIB Structure
A-2 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.
