Internet Group Management Protocol (IGMP)

The IGMP commands are supported by the Dell Force10 operating software (FTOS) on the E-Series, C-Series, S-Series,

Z-Series, and S4810 platforms.

This chapter contains the following sections:

IGMP Snooping Commands

IGMP Commands

FTOS supports IGMPv1/v2/v3 and is compliant with RFC-3376.

Important Points to Remember

FTOS supports protocol-independent multicast-sparse (PIM-SM) and protocol-independent source-specific

multicast (PIM-SSM) include and exclude modes.

IGMPv2 is the default version of IGMP on interfaces. You can configure IGMPv3 on interfaces. It is backward

compatible with IGMPv2.

The maximum number of interfaces supported is 512 on the E-Series. On the C-Series and S-Series, the

maximum number of interfaces supported 31. The Z9000 supports up to 95 interfaces.

There is no hard limit on the maximum number of groups supported.

IGMPv3 router interoperability with IGMPv2 and IGMPv1 routers on the same subnet is not supported.

An administrative command (ip igmp version) is added to manually set the IGMP version.

All commands previously used for IGMPv2 are compatible with IGMPv3.
