DLM-MIB device MIB details by Enterasys Networks Inc

DLM-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
                "A list of SNMP poll entries which trigger automatic polling
                of SNMP requests to other SNMP agents.  This table is indexed 
                by the destination IP address of the host/device to be polled
                and the IP address of the requesting host.  This indexing pair 
                allows multiple requestors to define a poll request to the same 
                destination, yet maintain separate poll entries.

                The OIDs to be polled in this request are defined in the 
                snmpOIDTable which is indexed also by the destination/owner
                IP address pair.  If no OIDs are defined for a poll entry, then
                the the poll will default to polling for sysUpTimei with no
                threshold comparison.  This will act as a simple keep-alive
                funtion for the destination SNMP agent."
