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 value of activePersistent, activeOnDemand and passive means this DLSw will accept any transport connections, initiated by partner DLSw nodes, which are defined by this conceptual row. The value of activePersistent means this DLSw will also initiate the transport connections of this conceptual row and retry periodically if necessary. The value of activeOnDemand means this DLSw will initiate a transport connection of this conceptual row, if there is a directory cache hits. The value of other is implementation specific. The value of exclude means that the specified node is not allowed to be a partner to this DLSw node. To take a certain conceptual row definition out of service, a value of notInService for dlswTConnConfigRowStatus should be used."

Only SAPs with even numbers are represented, in the form of the most significant bit of the first octet representing the SAP 0, the next most significant bit representing the SAP 2, to the least significant bit of the last octet representing the SAP 254. Data link switching is allowed for those SAPs which have one in its corresponding bit, not allowed otherwise. The whole SAP list has to be changed together. Changing the SAP list affects only new circuit establishments and has no effect on established circuits. This list can be used to restrict specific partners from knowing about all the SAPs used by DLSw on all its interfaces (these are represented in dlswIfSapList for each interface). For instance, one may want to run NetBIOS with some partners but not others. If a node supports sending run-time capabilities exchange messages, changes to this object should cause that action.

The managed node sends this value as its initial receive pacing window in its initial capabilities exchange message. Changing this value does not affect the initial circuit receive pacing window size of currently active transport connections. If the standard window pacing scheme is not supported, the value is zero.

Once initial Capabilities Exchange is sent, the transport connection enters enters -initCapExchange- state.

When DLSw is in the process of bringing down the connection, it is in the -disconnecting- state. When the transport layer indicates one of its connections is disconnected, the transport connection moves to the -disconnected- state. Whereas all of the values will be returned in response to a management protocol retrieval operation, only two values may be specified in a management protocol set operation, -quiescing- and -disconnecting-. Changing the value to -quiescing- prevents new circuits from being established, and will cause a transport disconnect when the last circuit on the connection goes away. Changing the value to -disconnecting- will force off all circuits immediately and bring the connection to -disconnected- state." ::= { dlswTConnOperEntry 6 } dlswTConnOperConfigIndex OBJECT-TYPE SYNTAX INTEGER ACCESS read-only STATUS mandatory DESCRIPTION "The value of dlswTConnConfigIndex of the dlswTConnConfigEntry that governs the configuration information used by this dlswTConnOperEntry.

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.

With the value of `disabled' the DLSw will not emit traps when connections enter of `connected' and `disconnected' states. With the value of `partial' the DLSw will only emits transport connection down traps when the connection is closed with busy. The changes take effect immediately." ::= { dlswTrapControl 3 } dlswTrapCntlCircuit OBJECT-TYPE SYNTAX INTEGER { enabled (1), disabled (2) } ACCESS read-write STATUS mandatory DESCRIPTION "Indicates whether the DLSw is permitted to generate circuit up and down traps. With the value of `enabled' the DLSw will emit traps when circuits enter `connected' and `disconnected' states. With the value of `disabled' the DLSw will not emit traps when circuits enter of `connected' and `disconnected' states. With the value of `partial' the DLSw will emit traps only for those circuits that are initiated by this DLSw, e.g., originating the CUR_CS message.
