Changes
Configured sFlow ('
code:
set sflow...
'; 12908).
The configured unit or stack was then reset/rebooted for any reason.

Symptoms
Configured sFlow receivers (except for IP address) have been cleared, so are no longer present in the configuration.

A few error messages may be seen on the console; for example:

code:
Incorrect input! Invalid Receiver index value.

-and/or-
code:
Incorrect input! First assign Receiver index.

-and/or-
code:
Incorrect input! Receiver is not associated with this poller instance.


Cause
This is directly related to the NetSight Inventory Manager fix outlined in 13974.

As a result of that fix, most of the sFlow configurations are now only present in Dynamic RAM (DRAM) rather than also being saved to non-volatile Flash memory, so most sFlow commands are not restored after a system reset.

As of the above-stated firmware version, this sFlow configuration loss behavior upon reset now matches what has always occurred upon sFlow timer expiration (13973).

Solution/Workaround
Functions as Designed (FAD).

Workaround: As desired, re-enter the missing sFlow commands.
