config igmp_snooping
host_timeout <sec 1-16711450>
−
Specifies the maximum amount of time a
host can be a member of a multicast group without the Switch receiving a host
membership report. The default is
260
seconds.
Note:
This parameter only displays the host timeout information. Users can
configure it, but it will not take effect.
router_timeout <sec 1-16711450>
−
Specifies the maximum 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.
Note:
This parameter only displays the router timeout information. Users can
configure it, but it will not take effect.
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.
Note:
This parameter only displays the leave timer information. Users can
configure it, but it will not take effect.
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.
Note:
host_timeout
,
router_timeout
and
leave_timer
parameters are used as
backwardly compatible command parameters due to configuration legacies.
Restrictions
Only Administrator and Operator-level users can issue this command.
Example usage:
To configure IGMP snooping:
DGS-3627:5#config igmp_snooping vlan default host_timeout 250 state enable
Command: config igmp_snooping vlan default host_timeout 250 state enable
Success.
DGS-3627:5#
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.
