Re: urgent igmp


I have a 720 here and the command works per guidelines:

no ip igmp snooping ?

l2-entry-limit limit on the l2 entry that can be installed by IGMP snooping

limit Configure IGMP Snooping limits

However, I have SXF here, I wonder if SXE did not provide the ability to disable IGMP snooping.
