Configures the maximum number of unique entries (channel or group) that can be learned simultaneously on this interface. The fsSnoopEnhPortMaxLimitType must be set before configuring this object. However the Max-limit is configurable even if the limit type is 'none', but the limit won't be in effect unless the limit type is set as 'channels' or 'groups'. If fsSnoopEnhPortMaxLimitType is 'channels', this limit applies to number of channels that can be joined on this interface. If fsSnoopEnhPortMaxLimitType is 'groups', this limit applies to number of groups that can be joined on this interface. By default, this object will hold a value of zero and will not limit any IGMP packets as long as the value of fsSnoopEnhPortMaxLimitType is set to 'none'. However, when fsSnoopEnhPortMaxLimitType is set to 'groups' or 'channels', if this object has the value of zero, then no IGMP reports will be processed on this interface. The maximum value supported by this object is dependent on the maximum groups or channels registrations that the system can support.
