igmp-snooping vlan disable - ex4300

Hi All,

i need to disable igmp-snoopong on spesific vlan on  ex4300 sw.

as i undrestand that option isnt available on that sw model: 

for now is connfigured as default  :

"set protocols igmp-snooping vlan all"

i tried to "set protocols igmp-snooping" configure on any vlan except the vlan that i need him to be disable and there were a lot of problems (loss my connection to the sw and all the isis connectivity got down)

i know that i can desable igmp-snoopong on a vlan at 4200 .

thank you all for the help.
