config igmp_snooping
Purpose Used to configure IGMP snooping on the Switch.
Syntax
config igmp_snooping [vlan_name <vlan_name 32> | all] {host_timeout
<sec 1-16711450> | router_timeout <sec 1-16711450> | leave_timer <sec 1-

Description This command allows the user to configure IGMP snooping on the Switch.
Parameters
vlan_name <vlan_name 32> − The name of the VLAN for which IGMP
snooping is to be configured.
all – Selecting this parameter will configure IGMP for all VLANs on the Switch.
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> − Leave timer. The default is 2 seconds.
state [enable | disable] − Allows the user 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.
Only administrator-level users can issue this command. Restrictions
