seems somewhat excessive in any case, and I'm not sure if this deserves handling apart from QoSing those streams to manageable levels. Yes, that would provide a solution. I havent seen anything where you can rate limit the learning(SA lookup failure). cheers, jamal -- To unsubscribe from

dont see any issues with those requirements being met. Jamal, so why do They have to be different calls? I'm not so sure anymore... moving to RTM_FDB_XXXENTRY saved some refactoring in the bridge module but that is just cosmetic. I may not want to use the s/ware bridge i.e I may want to use h
