config igmp_snooping
Purpose Used to configure IGMP snooping on the Switch.
Syntax
config igmp_snooping [vlan <vlan_name 32> | all]
{host_timeout <sec 1-16711450> | router_timeout <sec 1-16711450> |
leave_timer <sec 1-16711450> | state [enable | disable] |
fast_leave [enable | disable]}
Description This command allows users to configure IGMP snooping on the Switch.
Parameters
vlan <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. 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-level users can issue this command.
