CISCO-ISDN-MIB device MIB details by Cisco

CISCO-ISDN-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.

-- The ISDN hardware interface (BRI or PRI) will be represented
-- by the D channel. This will have an ifType value of basicISDN(20)
-- or primaryISDN(21), refer to RFC 1213. Each  B channel will
-- also be represented in an an entry in the ifTable. The B
-- channels will have an ifType value of other(1).
-- This model will be used while defining objects and tables
-- for management.
-- The ISDN MIB will allow sub-layers. For example, the data transfer
-- over a B channel may take place with PPP encapsulation. While the
-- ISDN MIB will describe the B channel, a media specific MIB for
-- PPP can be used on a layered basis. This will be as per RFC 1573.
-- The isdn call information will be stored in the neighbor table
