CISCO-DIAL-CONTROL-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 mib is an extension to the RFC 2128
-- 
-- The RFC 2128 (Dial Control Mib) defines callHistoryTable, which is
-- the table that stores past call information. Unfortunately, the indices
-- to this table (callActiveSetupTime, callActiveIndex) are not appropriate
-- for the NMS to retrieve information on regular intervals.
-- 
-- The following changes in the RFC2128 will fix the INDEX of the
-- callHistoryTable. This will also make the mib useful for various types 
-- of calls, including ISDN data, voice, modem. VoIP etc. Right now, the 
-- NMS needs to poll three different mibs (CISCO-CALL-HISTORY-MIB.my, 
-- CISCO-POP-MGMT-MIB.my and the DIAL-CONTROL-MIB.my) for these calls.
--
-- We'll attempt to forward these changes to the ISDN working group
-- so that it may be discussed and approved for the next draft of the
-- RFC 2128.
