config igmp_snooping
host membership report. The default is 260 seconds.
leave_timer <sec 1-16711450> − Specifies the amount of time a Multicast
address will stay in the database before it is deleted, after it has sent out a
leave group message. The default is 2 seconds.
state [enable | disable] − Allows you to enable or disable IGMP snooping for
the specified VLAN.
fast_leave [enable | disable] – This parameter allows the user to enable the
fast leave function. Enabled, this function will allow members of a multicast
group to leave the group immediately (without the implementation of the Last
Member Query Timer) when an IGMP Leave Report Packet is received by the
Switch.
Restrictions Only administrator-level users can issue this command.
Example usage:
To configure IGMP snooping:
DGS-3600:4#config igmp_snooping vlan default host_timeout 250 state enable
Command: config igmp_snooping vlan default host_timeout 250 state enable
Success.
DGS-3600:4#
NOTE: The IGMP Snooping VLAN function is supported when the Switch is in
standalone mode only.
NOTE: The Fast Leave function in the config igmp_snooping command can only
be implemented if IGMP is disabled for all IP interfaces on the Switch. Configuring
this function when IGMP is enabled will produce the error message “Cannot set
Fast leave when IGMP is running” and consequently will not be implemented.
