igmpsnooping fast-leave
no igmpsnooping fast-leave
The following example enables fast-leave mode on an interface:
(SafeGuardOS) #configure terminal
(SafeGuardOS) (config) #vlan database
(SafeGuardOS) (interface interface 0/3) #igmpsnooping fast-leave
(SafeGuardOS) (interface interface 0/3) #exit
(SafeGuardOS) (config) #exit
(SafeGuardOS) #
Creating a Static Connection to a Multicast Router
To enable a static connection to a multicast router, use the igmpsnooping mrouter
command in Interface Configuration mode. Use the no version of the command to
disable the interface.
igmpsnooping mrouter vlan vlanid
no igmpsnooping mrouter vlan vlanid
The following example enables static connection to a multicast router on the VLAN
running over interface 0/5, which has a VLAN ID of 85:
(SafeGuardOS) #configure terminal
(SafeGuardOS) (config) #interface 0/5
(SafeGuardOS) (interface interface 0/5) #igmpsnooping mrouter vlan 85
(SafeGuardOS) (interface interface 0/5) #exit
(SafeGuardOS) (config) #exit
(SafeGuardOS) #
To verify the configuration, use the Privileged Exec show igmpsnooping mrouter
command. This command is described further in Displaying Static Configurations to a
Multicast Router on page 174.
Clearing IGMP Snooping Entries Globally
To clear the MAC multicast tables managed by IGMP Snooping and to delete these
entries from the multicast Forwarding Database, use the clear igmpsnooping command
in Privileged Exec mode. The command has no parameters or variables.
The following example clears IGMP Snooping entries globally:
(SafeGuardOS) #clear igmpsnooping
(SafeGuardOS) #
Syntax Description vlanid Enables a static connection to a multicast
router on a VLAN having this identification
