IGMP Snooping
Internet Group Management Protocol (IGMP) is used by IP hosts to register their dynamic multicast
group membership. IGMP has 3 versions, IGMP v1, v2 and v3. Please refer to RFC 1112, 2236
and 3376. IGMP Snooping improves the performance of networks that carry multicast traffic. It
provides the ability to prune multicast traffic so that it travels only to those end destinations that
require that traffic and reduces the amount of traffic on the Ethernet LAN.

SNMP Configuration
Simple Network Management Protocol (SNMP) is the protocol developed to manage nodes
(servers, workstations, routers, switches and hubs etc.) on an IP network. SNMP enables network
administrators to manage network performance, find and solve network problems, and plan for
network growth. Network management systems learn of problems by receiving traps or change
notices from network devices implementing SNMP.
