Hello, Have a Cisco 3560 running "flash:/c3560-ipbasek9-mz.122-55.SE1.bin". Been running at 20% CPU since we started it: [image: plf-access - CPU Usage] The switch is completely layer-2... basic configuration. CPU utilization is soley based on a single process: plf-access#sh proc cpu sorted CPU utilization for five seconds: 27%/0%; one minute: 25%; five minutes: 24% PID Runtime(ms) Invoked uSecs 5Sec 1Min 5Min TTY Process 41 232891470 1072247 217210 20.12% 18.99% 18.01% 0 SFF8472 78 2376721 123621 19225 0.95% 0.22% 0.17% 0 HULC Tcam Memory 303 299 163 1834 0.47% 0.23% 0.07% 2 SSH Process 55 106535 11303527 9 0.15% 0.02% 0.00% 0 RedEarth Tx Mana Anybody have a clue what this process is?

You mean the RedEarth process?

I suspect he meant the SFF8472 process, using 20% of CPU...
plf-access#sh proc cpu sorted CPU utilization for five seconds: 27%/0%; one minute: 25%; five minutes: 24% PID Runtime(ms) Invoked uSecs 5Sec 1Min 5Min TTY Process 41 232891470 1072247 217210 20.12% 18.99% 18.01% 0 SFF8472
SFF-8472 is the standard for monitoring mini-GBIC/SFP modules - perhaps he has a 'bad' module in this router that's going haywire? -- James.

SFF8472 is very familiar: http://en.wikipedia.org/wiki/Small_form-factor_pluggable_transceiver#Digital... I believe that might help explain a little. I also found reference to it buried in a PDF: http://bit.ly/fZZcVp So you may have some incompatible SFP there. HTH Tom
