CISCO-VOICE-ENABLED-LINK-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
        "This MIB module provides information about Voice Enabled
         ATM and Frame Relay Links used by the Cisco Switched
         voice protocol.
         The Cisco Switched voice protocol passes the default MAC
         address for its node to the next node in the path, in both
         call setup messages and keepalive requests and responses.
         This MAC address is stored at the remote node to identify
         where the incoming pvc originates. This information is then
         used by the Cisco Voice Manager Application to determine
         the voice network topology."
