Config Igmpsnooping Interface Mode; Show Mfdb Table - NETGEAR GSM7324 Reference Manual

config igmpsnooping interface mode

This command enables or disables IGMP Snooping on a selected interface. The <slot.port/all>
parameter identifies the interface on which to configure the mode. If an interface which has IGMP
Snooping enabled is enabled for routing or is enlisted as a member of a LAG, IGMP Snooping
functionality will be disabled on that interface. IGMP Snooping functionality will subsequently be
re-enabled if routing is disabled or LAG membership is removed from an interface that has IGMP
Snooping enabled.

Format

A unicast MAC address for which the switch has forwarding and
or filtering information. The format is 6 or 8 two-digit hexadeci-
mal numbers that are separated by colons, for example
01:23:45:67:89:AB. In an IVL system the MAC address will be
displayed as 8 bytes. In an SVL system, the MAC address will be
displayed as 6 bytes.
This displays the type of the entry. Static entries are those that are
configured by the end user. Dynamic entries are added to the
table as a result of a learning process or protocol.
The component that is responsible for this entry in the Multicast
Forwarding Database. Possible values are IGMP Snooping,
GMRP, and Static Filtering.
The text description of this multicast table entry.
The list of interfaces that are designated for forwarding (Fwd:)
and filtering (Flt:).
The resultant forwarding list is derived from combining all the
component's forwarding interfaces and removing the interfaces
that are listed as the static filtering interfaces.
