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.

state [enable | disable]
−
Allows the user to enable or disable IGMP snooping
