Table 62 igmp-snooping vlan Command Summary
COMMAND DESCRIPTION M P
show igmp-snooping vlan Displays the VLANs on which IGMP snooping is enabled. E 3
igmp-snooping vlan mode
<auto|fixed>
Specifies how the VLANs on which the Switch snoops IGMP
packets are selected.
auto: The Switch learns multicast group membership on any
VLAN. See the User’s Guide for the maximum number of
VLANs the switch supports for IGMP snooping. The Switch
drops any IGMP control messages on other VLANs after it
reaches this maximum number (auto mode).
fixed: The Switch only learns multicast group membership
on specified VLAN(s). The Switch drops any IGMP control
messages for any unspecified VLANs (fixed mode). See the
User’s Guide for the maximum number of VLANs the switch
supports for IGMP snooping.
C13
igmp-snooping vlan <vlan-id>
[name <name>]
Specifies which VLANs to perform IGMP snooping on if the
mode is fixed. Optionally, sets a name for the multicast
VLAN.
name: 1-32 printable characters; spaces are allowed if you
put the string in double quotation marks (“).
C13
no igmp-snooping vlan <vlan-id> Removes IGMP snooping configuration on the specified
VLAN if the mode is fixed.

show interfaces config <port-
list> igmp-group-limited
Displays the group limits for IGMP snooping. E 3
show interfaces config <port-
list> igmp-immediate-leave
Displays the immediate leave settings for IGMP snooping. E 3
show interfaces config <port-
list> igmp-query-mode
Displays the IGMP query mode for the specified port(s). E 3
show interfaces config <port-
list> igmp-snooping filtering
Displays the name(s) of the IGMP filtering profiles used for
the specified port(s).
E3
show interfaces config <port-
list> igmp-snooping group-
limited
Displays whether the group limit is enabled and the maximum
number of the multicast groups the specified port(s) is
allowed to join.
E3
show interfaces config <port-
list> igmp-snooping leave-mode

Enters config-interface mode for the specified port(s). C 13
igmp-snooping fast-leave-
timeout <200-6348800>
Set the IGMP snooping fast leave timeout (in miliseconds) the
Switch uses to update the forwarding table for the port(s).
This defines how many seconds the Switch waits for an IGMP
report before removing an IGMP snooping membership entry
when an IGMP leave message is received on this port from a
host.
C13
igmp-snooping filtering
profile <name>
Assigns the specified IGMP filtering profile to the port(s). If
IGMP filtering is enabled on the Switch, the port(s) can only
join the multicast groups in the specified profile.
