information. The format is 6 or 8 two-digit hexadecimal numbers that are sepa-
rated by colons, for example 01:23:45:67:89:AB. In an IVL system the MAC
address will be displayed as 8 bytes.

the end user. Dynamic entries are added to the table as a result of a learning pro-
cess or protocol.

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.
