config igmp_snooping
Purpose
Used to configure IGMP snooping on the Switch.
Syntax
config igmp_snooping [<vlan_name 32> | all] {host_timeout <sec 1-
16711450> | router_timeout <sec 1-16711450> | leave_timer <sec 0-
16711450> | state [enable | disable]} | fast_leave [enable | disable]}
Description
This command allows users to configure IGMP snooping on the Switch.
Parameters
<vlan_name 32>
−
The name of the VLAN for which IGMP snooping is to be
configured.
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.
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.
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 users 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 or Operator-level users can issue this command.
