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 Commands
•
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.
