IGMP snooping is enabled by default on switchports. If it is disabled in your switch you can enable it using global command "ip igmp snooping"
sh ip igmp int g2/1 shows as IGMP disabled because it is a layer 2 port. If it were a routed port and you had an IP address and PIM enabled, you would have seen it as enabled.
