config igmp_snooping
Switch receiving a 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. An entry of zero (0) specifies
an immediate deletion of the Multicast address. 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:
DES-3800:4#config igmp_snooping default host_timeout 250 state
enable
Command: config igmp_snooping default host_timeout 250 state
enable
Success.
DES-3800:4#
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.
