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

Yves_Haslimann — Wed, 28 Feb 2018 15:24:00 GMT

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

Hello, I have made this working in my lab using Analytics 8.1.1EA2 and it is possible,. Some manual actions are needed on XMC but after that it can work. You could run into problems due to ACL limitations on the X440G2 but it can work.

Hi Oskar, I have the same Analytics version running. Do you have a configuration example or a documentation of this? Thank you.

Ok, some file editing is needed now to make it work.
On XMC, copy sflow,pol.
cp /usr/local/Extreme_Networks/NetSight/appdata/Purview/Fingerprints/sflow.pol /tftpboot/

On Analytics, edit file /opt/appid/conf/appidconfig.xml and change interfaces to be like:

Restart analytics or appid after this.

On XMC go to analytics, configuration and on your engine add an application telemetry source (the switch) and enforce.

Hi Oskar, it's me again. Are we talking here about sflow+ ? Because my workmate said, it has to run with sflow+ and not only with sflow.

I don't have a sflow.pol file.
And how/where can I add a "application telemetry source"?

What do I have to configure on the switch side?

Thank you

OscarK — Wed, 28 Feb 2018 16:17:00 GMT

You add the app telemetry source under flow sources.
Maybe the sflow.pol file is only created once you do a first enforce.
On the switch I think all should be configured by Analytics.

Yves_Haslimann — Wed, 28 Feb 2018 16:23:00 GMT

Okay, found it, thx.
I did an enforce (without adding a telemetry source) but the file isn't there yet.

I guess I have to test it first in the lab, before I add a switch to the Analytics on customer site. Because I have no idea how business critical this is.

I tried it with "Application Telemetry Source" (I guess this is for SFlow+).
But I got the following errors when I add the source Switch.

--> I've already run this command: "configure access-list vlan-acl-precedence shared" and rebooted the switch.

The configuration is a default setup.

Have the same problem on X440-G2:

this is a known CR, that will be fixed (if not already)

Try to configure the access-list width to double.
The command to do this is:

configure access-list width double

Hi Oscar,

I've also test this, but gets the same error as Yves & Bernhard. I've used 22.4.1.4-patch1-2, but we're also working with Policy enabled. So couldn't run the command:

configure access-list width double slot 1

WARNING: Configuration of double width access-list is not supported when Policy is enabled. Slots will remain in Single width mode.

Hello everybody: I got the following information: To use an ExtremeSwitching X440-G2 switch as an Application Telemetry source for ExtremeAnalytics, install firmware version 22.4.1.4-patch2-5 or higher.

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

Kevin_Beyers — Fri, 06 Apr 2018 17:13:00 GMT

Hi Yves,

Ok thanks for the information. The firmware 22.4.1.4-patch2-5 isn't yet available at the partner portal of Extreme Networks?

Kind Regards,
Kevin.

OscarK — Tue, 24 Apr 2018 13:20:00 GMT

Hello Kevin, 22.4.1.4-patch2-5 is a private patch and is not publically available. You can get this patch by opening a case.
22.5 will also contain the fix once it is available (expected end of May).

Hi Oscar,

Ok thanks for the information, I will contact Extreme GTAC.

Kind Regards,
Kevin.

Hi,

Just to let you know I'm running into this same problem using firmware version:

22.5.1.7

EMC = 8.1.3.65

Error is:

An error has occurred while adding a flow source to the selected engine. See details below for more information.

javax.script.ScriptException: *** Script Error *** Die command issued: Script failed : * POC.17 # configure access-list telemetry.pol any ingress . Error: ACL install operation failed - filter hardware full for vlan *, port * * POC.18 # -> if {! $OverallResult}

Am also running policy on this X440G2 switch, so setting the double width I get the following message:

* POC.1 # configure access-list width double
WARNING: Configuration of double width access-list is not supported when Policy is enabled. Slots will remain in Single width mode.

If I disable policy I can then run the access-list width double command, but when I re-enable policy I then get the following error:

* POC.4 # enable policy
Warning: Enabling Policy will cause some Netlogin settings (such as VLANs and dynamically created VLANs) to be cleared.
ERROR: Hardware resources could not be reserved for Policy (count 0).
Note that Policy cannot be enabled when double width access-list is configured or operational.

Previously upgraded from version 22.4.1.4-patch1-2

Post mentions this being fixed in version 22.5, so not sure what I am doing wrong or how to fix / get this working?

Seen this command that could be used to adjust ACL usage, but not sure exactly the syntax to use that would help:

configure policy resource-profile default profile-modifier [no-mac|no-ipv4|no-ipv6] enable

I've tried removing no-ipv6, but no difference?

Many thanks.

Hi,
can you show the output of "show sflow hardware-utilization"?
