116
igmp-snooping host-timeout <1-
16711450>
Sets the host timeout value. C 13
igmp-snooping leave-timeout <1-
16711450>
Sets the leave timeout value C 13
igmp-snooping querier Enables the IGMP snooping querier on the Switch. C 13
no igmp-snooping querier Disables the IGMP snooping querier on the Switch. C 13
igmp-snooping leave-proxy 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.
C13
no igmp-snooping leave-proxy 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.
C13
igmp-snooping report-proxy 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.
C13
no igmp-snooping report-proxy 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.
C13
igmp-snooping reserved-multicast-
frame <drop|flooding>
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.
C13
igmp-snooping unknown-multicast-
frame <drop|flooding>
Sets how to treat traffic from unknown multicast groups. C 13
show igmp-snooping Displays global IGMP snooping settings. E 3
show igmp-snooping filtering
profile
Displays IGMP filtering profile settings. E 3
show igmp-snooping group all Displays all multicast group information. E 3
show igmp-snooping group client <
[vlan <vlan-list>] [interface
port-channel <port-list>]
[multicast-group <group-address>]
>
Displays client IP information for the specified multicast
VLAN(s), port(s) and/or multicast group(s).
E3
show igmp-snooping group client
all
Displays client IP information for all multicast groups on
the Switch.
E3
show igmp-snooping group count Displays the total number of the multicast groups on the
Switch.
