4.3 ExtremeAnalytics Upgrade Information
Enabling or disabling the disk flow export feature might cause enforce
operations to time out. Enforcing again resolves the issue.
When you delete an ExtremeXOS device that is configured as a flow source via
the Flow Sources table of the Analytics > Configuration > Engines >
Configuration tab from the Devices list on the Network > Devices tab, an error
message is generated in the server.log. The message does not warn you that
the device is in use as a flow source. Adding the device back in the Devices list
on the Network > Devices tab or removing the device from the Flow Source table
fixes the issue.
The Flow Sources table on the Analytics > Configuration > engine >
Configuration tab may take a few minutes to load.
