The default is 260 seconds. router_timeout − 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 − 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. Only Administrator or Operator-level users can issue this command. 123
