Novell-LANalyzer-TR-MIB device MIB details by Novell

Novell-LANalyzer-TR-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.

-- The Statistics Group

-- The statistics group in token ring remote network monitoring MIB contains
-- counters for MAC layer frame and byte throughput in terms of promiscuous,
-- multicast and broadcast address.  Also, it contains counters for MAC layer
-- state transitions, MAC and physical layer errors and the size distribution
-- of data frames.  The data frame size distribution is subjected to the view
-- with which the tokenRingStatsDataSource object is associated.

-- The History Group

-- The history group periodically takes statistical samples from a network
-- and stores them for later retrieval.  The counters in the history group
-- is a subset in the statistics group.  In the history group, the counters
-- contain the statistics accumulated during the last sample.

-- The objects and structure in the history group are the same between Ethernet
-- and token ring remote network monitoring MIBs, except that the prefix of
-- the objects' names are changed from "ether" to "tokenRing" and the counters
-- in EtherHistoryEntry are replaced by the counters in TokenRingHistoryEntry.
-- The token ring history shares the control table with the ethernet version;
-- it is in the rmon mib.

-- The MIB address of the objects are enumerated from 1 to infinity.  The
-- address of the first object, which is tokenRingHistoryIndex , is
-- { tokenRingHistoryEntry 1 }, and so on.
