We have quite a few Brocade devices in our network. Some of those devices are working flawlessly with NTA, the others are sending data (verified by applying show slow to the Brocade devices) but NTA does not get the data. I see the interfaces, and I also see the transmit and receive information, but zero sflow data. The devices that are working are all on Sflow version 5. When I try to obtain the version number on the Brocade devices that do not work, I am not able to. I am assuming those to be on version 2. Does NTA support Sflow version 2? If it does, what else could I look at?
