Command
History
Version 9.2(0.0) Introduced on the M I/O Aggregator. This command is
supported in Programmable-Mux (PMUX) mode only.
Version 8.3.16.1 Introduced on the MXL 10/40GbE Switch IO Module.
Usage
Information
If you use this command to configure the minimum number of links in a LAG that
must be in “oper up” status, the LAG must have at least that number of “oper up”
links before it can be declared as up. For example, if the required minimum is four,
and only three are up, the LAG is considered down.
Internet Group Management Protocol (IGMP)
The IGMP commands are supported by the Dell Networking operating software on the Aggregator.
This chapter contains the following sections:
• IGMP Commands
• IGMP Snooping Commands
IGMP Commands
Dell Networking OS supports IGMPv1/v2/v3 and is compliant with RFC-3376.
Important Points to Remember
• IGMPv2 is the default version of IGMP on interfaces. You can configure IGMPv3 on interfaces. It is
backward compatible with IGMPv2.
• 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.
