CISCO-IGMP-SNOOPING-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 
        "The MIB module for IGMP Snooping feature. 

         Internet Group Management Protocol (IGMP) is the protocol used 
         by IPv4 end hosts to indicate their interest in receiving 
         multicast traffic for certain multicast groups to neighboring 
         multicast routers. Version 3 of IGMP adds support for source 
         based filtering; which means the end hosts can specifically 
         indicate to receive or not-receive multicast packets from 
         specific source addresses. This information is used by the 
         multicast routers to restrict forwarding of multicast traffic 
         for the host.

         IGMP Snooping is a switch protocol. A switch that implements 
         IGMP Snooping listens to the IGMP messages exchanged between 
         the hosts and router, then provides selective transmission of 
         multicast traffic based on multicast mac destination address
         or multicast group address.  With IGMPv3 support, 
         IGMP Snooping can potentially provide selective transmission
         of multicast data based on (source address, group address) 
         onto the ports that are interested. In addition to this, 
         IGMP Snooping can also provide proxy reporting, report 
         suppression and fast leave capabilities."
    
    REVISION    "200303240000Z"
    DESCRIPTION
        "Add support for the following:
         - per VLAN IGMP Snooping configuration and group
           membership information
         - per port IGMP Snooping configuration
         - per VLAN IGMP Querier configuration
         - global rate-limit control objects

           configuration related objects."
