A3Com-Mip-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.

      --This data type, which has the same semantics as the rowStatus
      --textual convention used in SNMPv2, is used to add and 
      --delete entries from a table.

      --The tables in this MIB allow a subset of the functionality
      --provided by the rowStatus textual convention.  In particular
      --row creation is allowed using only the createAndGo method.

      --That is, when adding entries to this table, this object
      --must be set to createAndGo(4).  The instance identifier
      --for this object will define the values of the columns 
      --that make up the index.  

      --In the same PDU, the appropriate remaining columns
      --of that row must be set as well.  The agent
      --will immediately set the value of this object to
      --active(1) if the row is correct.  If not, the agent
      --will refuse the SET request and return an
      --error code.

      --To modify an existing entry, it must be removed
      --and another entry with the desired changes added. 
                   
      --To remove an entry, set the value of this object
      --to destroy(6).
