I wonder if you were seeing 14% CPU over 5min avg BECAUSE the SFP supported DOM or was it a bug due to DOM. In other words, maybe the fact that the SFP supported DOM just took up a bit more CPU due to the diagnostic function. Is it normal I guess is what I'm wondering... -J On Tue, Mar 29, 2011 at 3:38 PM, Joe Renwick <joe@gonetforward.com> wrote:
So thanks to all for the help. It was an SFP. Here is CPU with bad SFP:
plf-access#
plf-access#sh proc cpu sorted
CPU utilization for five seconds: 11%/0%; one minute: 18%; five minutes: 21%
PID Runtime(ms) Invoked uSecs 5Sec 1Min 5Min TTY Process
41 237737055 1095169 217078 5.11% 11.74% 14.87% 0 SFF8472
Here is CPU with SFP taken out:
plf-access#sh proc cpu sorted
CPU utilization for five seconds: 5%/0%; one minute: 17%; five minutes: 21%
PID Runtime(ms) Invoked uSecs 5Sec 1Min 5Min TTY Process
106 322 437 736 0.79% 0.07% 0.03% 0 Exec
Confirmed it was the SFP by pulling it in and out a couple times. Processor flapped right along.
Thanks again to all,
Joe
"Well, I have no direct experience with the 3560, but SFF-8472 is a spec that includes diagnosting monitoring of SFPs..."

It was consistent... Since I started managing the device with Cacti on Sunday it was dead red at that level. Was an SFP... going to post a response now.

Hey Joe,
Is the CPU usage consistent or fluctuating?

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?
Thanks for the time.
