Suppose you need to enable IGMP Snooping on VLAN1. The procedures are as 

follows: 

Display the current state of IGMP Snooping. 

<SW8800> display igmp-snooping configuration 

If IGMP Snooping is not enabled, enable it in system view. 

[SW8800] igmp-snooping enable 

Display the status of the VLAN1 interface, to check if PIM or IGMP is enabled on it.  

[SW8800] display current-configuration interface Vlan-interface 1 

If PIM or IGMP is not running on VLAN1, you can enable IGMP Snooping in VLAN view. 

[SW8800-vlan1] igmp-snooping enable 

Fault: Multicast function cannot be implemented on the switch.
