Internet Group Management Protocol (IGMP)
The IGMP commands are supported on the S5000 switch.
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 31 on the S5000.
• 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.
