config igmp_snooping
amount of time a route can be a member of a multicast group
without the Switch receiving a host membership report. The
default is 260 seconds.
leave_timer <sec 1-16711450>
−
Leave timer. 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.
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.
Example usage:
To configure igmp snooping including fast leave.:
DGS-3324SRi:4#config igmp_snooping default host_timeout 250 state enable
fast_leave enable
Command: config igmp_snooping default host_timeout 250 state enable
fast_leave enable
Success.
