Oh and the pps tax for a feature is not constant either and might change with a new code release, cause the SW paths are being streamlined.
What is striking though is that we could live without any kind of telemetry from forwarding ASICs/NPUs up until now. adam netconsultings.com ::carrier-class solutions for the telecommunications industry:: _______________________________________________ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
