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.

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 - extend the cisSystemInfo to include more IGMP Snooping configuration related objects."
