Sending flow data from a switch direct to ExtremeAnalytics (without a flowcollector engine)

[Yves_Haslimann]

Hello everybody

I would like to configure the Extreme Switches (x440-G2, with version 22.4) to sending sflow/netflow data direct to the Extreme Analytics. I heard this is now possible without having a flowcollector enginge like PV FC-180 installed. Is this true? Because I couldn't find any referenced documentation to this. Thank you very much for your feedback.

Best regards, Yves

that's certainly a wise decision, playing all around with the ACL config as you did, you may have some leftovers.

Make sure CoS is disabled in Policy Manager, like that:

So I've tried all the above and removed all the QoS config I can, but still the ACL slices will not budge, so no idea what's using them?

Think the only way I'm going to be able to straighten it out I think is wipe the switch and start again.

Thanks for all your effort anyway.

Thanks Stephane, shall try this out and post back. I haven't got double width enabled. I did try it, but removed it as I couldn't enable policy.

btw, you are not using double width ACL, right? You should not.

A fresh x440G2 (default config) should use only 1 slice.

Telemetry + Policy should leave you with 1 slice free.

You could try disabling diffserv examination and dot1p examination and turn off port qos (config port qosprofile none). If all else fails, you can reduce policy to just L2 rules via:



config policy resource-profile default profile-modifier no-ipv4 enable



This will require disable/enable policy but will effectively reserve/consume only 2 slices (instead of 4) for policy.
