Internet Group Management Protocol (IGMP) Commands

This chapter provides a detailed explanation of the IGMP commands. The commands are divided into two functional groups:

•Show commands display switch settings, statistics, and other information.

•Configuration commands configure features and options of the switch. For every configuration command, there is a show command that displays the configuration setting.

set igmp

This command enables IGMP Snooping on the system. The default value is disable.

Note: The IGMP application supports the following:

•Global configuration or per interface configuration. Per VLAN configuration is unsupported in the IGMP snooping application.

•Validation of the IP header checksum (as well as the IGMP header checksum) and discarding of the frame upon checksum error.

•Maintenance of the forwarding table entries based on the MAC address versus the IP address.

•Flooding of unregistered multicast data packets to all ports in the VLAN.
