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 (“).

no igmp-snooping vlan <vlan-id> Removes IGMP snooping configuration on the specified
VLAN if the mode is fixed.
