[f-nsp] MLX-4 SFLOW issues?

[Skylar MacMinn]

We recently swapped off of an RX-4 to an MLX-4, we are using WANGUARD with SFLOW to monitor our network traffic. The RX-4 worked well enough. The issue with our MLX-4 is SFLOW is recording on average about 80-100Mbps vs the 800-1000Mbps we run regularly. SNMP appears to record data fine, but the SFLOW is inaccurate by a very large degree.

We've worked with wanguard on it, as well as used other methods of validating the sflow data - at this time we have verified that the issue is with SFLOW itself on the router, and not a configuration issue within the software we are using to monitor the data.

Our current installed firmware is the following:

Any and all help is greatly appreciated! For the time being we'd prefer to keep using SFLOW until we can transition into something more reliable, but this should be working fine. We have validated that configuration of sflow is where it should be, so the results should at least be somewhat closer to reality.

Cordially Yours,
