DESCRIPTION
Sets the host timeout value.
Sets the leave timeout value
Enables the IGMP snooping querier on the Switch.
Disables the IGMP snooping querier on the Switch.
Enables IGMP snooping leave-proxy mode.
In this mode, the Switch sends a leave message with its
MAC address to the multicast router/switch only when it
receives the leave message from the last host in a
multicast group.
Disables IGMP snooping leave-proxy mode.
In this mode, the Switch just snoops on and sends the
multicast router/switch all IGMP leave messages without
changing their source MAC addresses.
Enables IGMP snooping report-proxy mode.
In this mode, the Switch acts as an IGMP v1/v2 report
proxy. The Switch not only checks IGMP packets between
multicast routers/switches and multicast hosts to learn the
multicast group membership, but also replaces the source
MAC address in an IGMP v1/v2 report with its own MAC
address before forwarding to the multicast router/switch.
When the Switch receives more than one IGMP v1/v2 join
reports that request to join the same multicast group, it
only sends a new join report with its MAC address. This
helps reduce the number of multicast join reports passed
to the multicast router/switch.
Disables IGMP snooping report-proxy mode.
In this mode, the Switch just snoops on and sends the
multicast router/switch all IGMP join messages without
changing their source MAC addresses, and forwards
multicast traffic to the hosts.
Sets how to treat traffic with a reserved multicast address.
Reserved multicast addresses are in the range 224.0.0.0
to 224.0.0.255.
Sets how to treat traffic from unknown multicast groups.
Displays global IGMP snooping settings.
Displays IGMP filtering profile settings.
Displays all multicast group information.
Displays client IP information for the specified multicast
VLAN(s), port(s) and/or multicast group(s).
[interface
Displays client IP information for all multicast groups on
the Switch.
Displays the total number of the multicast groups on the
Switch.
