RTM-MIB file content

The SNMP protocol is used to for conveying information and commands between agents and managing entities. SNMP uses the User Datagram Protocol (UDP) as the transport protocol for passing data between managers and agents. The reasons for using UDP for SNMP are, firstly it has low overheads in comparison to TCP, which uses a 3-way hand shake for connection. Secondly, in congested networks, SNMP over TCP is a bad idea because TCP in order to maintain reliability will flood the network with retransmissions.

Management information (MIB) is represented as a collection of managed objects. These objects together form a virtual information base called MIB. An agent may implement many MIBs, but all agents must implement a particular MIB called MIB-II [16]. This standard defines variables for things such as interface statistics (interface speeds, MTU, octets sent, octets received, etc.) as well as various other things pertaining to the system itself (system location, system contact, etc.). The main goal of MIB-II is to provide general TCP/IP management information.

-- DESCRIPTION "This is the Robust Trap MIB(RTM) module.
--              RTM requires that each of the traps/notifications
--              have mandatory varbinds in the begining.
--              The mandatory varbinds are different in
--              different MGX products. However all the
--              RTM Compliant Traps(notifications) have to have 
--              'lastSequenceNumber' object
--              as the first varbind. The 'lastSequenceNumber' value
--              can be used by the SNMP managers to find the
--              lost/missing traps(notifications) from the system.
--
--              The word 'system'(running agent)applies to MGX series
--              products from Cisco Systems."
--              The word 'manager' applies to any SNMP
--              Manager application.
--
-- REVISION "200207090000Z"
-- DESCRIPTION
--    "- Added recoverTrapTable. This table can be used
--       for recovering traps from the system."
--
--       It is recommended that 'recoverTable' is used
--       instead of 'trapUploadTable' for recovering
--       lost traps.
--
-- REVISION "200108220000Z"
-- DESCRIPTION
--    "- Clarified the descriptions of the mib objects.
--     - SYNTAX range for managerNumOfValidEntries object
--       have been changed from (0..8) to (0..12).

    ACCESS  read-write
    STATUS  mandatory
    DESCRIPTION
        "This object is used for adding(registering) and
        deleting(de-registering) SNMP managers in the system.
        By setting this object to 'addRow' snmp manager will be
        registered with the system.

        By setting this object to 'delRow' snmp manager will be
        registered with the system.

        In some systems, the SNMP Manager will be de-registered
        automatically by the agent (to allow other SNMP managers
        to register), if manager is idle for long time(
        This time is called aging interval time).
        In order to avoid Managers being de-registered automatically
        it is expected that the SNMP Managers keep sending
        keep-alive requests(SNMP GET on this object)
        to the system for predefined interval(Choosen by
        SNMP Manager). The keep-alive requests need to be 
        sent few minutes before the aging interval expires.

        The aging value of the Registered Managers are in the 
        order of minutes(system dependent or user configured).
        The value supported for the aging value 
        is system dependent. The system might support
        aging value per manager basis or per node basis
        (applicable to all the registered managers).
