A3Com-DLSW-r1-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.

-- A circuit is the end-to-end association of two DLS entities
-- through one or two DLSw nodes.  It is the concatenation of
-- two "data links", optionally with an intervening transport
-- connection. Origin of the circuit is the end station which
-- initiates the circuit.  Target of the circuit is the end
-- station which receives the initiation.

    DESCRIPTION
       "This table is the circuit representation in the DLSw
        entity. Virtual data links are used to represent any internal
        end stations.  There is a conceptual row associated with
        each data link.  Thus, for circuits without an intervening
        transport connection, there are two conceptual rows
        for each circuit.
 
        The table consists of the circuits being established,
        established, and as an implementation option, circuits that
        have been disconnected.  For circuits carried over
        transport connections, an entry is created after
        the CUR_cs was sent or received.  For circuits between
        two locally attached devices, or internal virtual MAC
        addresses, an entry is created when the equivalent of
        CUR_cs sent/received status is reached.
 
        End station 1 (S1) and End station 2 (S2) are used to
        represent the two end stations of the circuit.
        S1 is always an end station which is locally attached.
        S2 may be locally attached or remote.  If it is locally
        attached, the circuit will be represented by two rows indexed
        by (A, B) and (B, A) where A & B are the relevant MACs/SAPs.
 
        The table may be used to store the causes of disconnection of
        circuits.  It is recommended that the oldest disconnected
        circuit entry be removed from this table when the memory
        space of disconnected circuits is needed."
