RedEarth processes on 3560 Switch

Elie Bassil

Hello,

We have recently bought/installed a 3560 Switch in our network, it is showing highest processes as "RedEarth" processes.

Cisco IOS Software, C3560E Software (C3560E-UNIVERSALK9-M), Version 12.2(58)SE1,

From what I was able to find is that "RedEarth Tx Mana" is related to "Microprocessor communication process"

On a Layer 3 switch, when the IP route is not known, the switch hardware punts (sends) IP packets to the CPU for IP routing. Punted packets are handled at the interrupt level and can cause the CPU to become too busy.

Can anyone provide additional information concerning those 2 processes? Any suggested commands to provide additional troubleshooting/information?

Thanks,

E.B:.

Anyone... ?

Hi Elie

I have a switch with exactly the same symptoms as you describe here. Did you get any answer in any other side?

Thanks

Hi!

No actually I didn't get a reply. What's the average CPU consumption on your switch? Can you post a "sh proc cpu sorted"?

CPU utilization for five seconds: 8%/0%; one minute: 9%; five minutes: 9%

PID Runtime(ms)   Invoked      uSecs   5Sec   1Min   5Min TTY Process

  60   702630240 159517322       4404  1.91%  2.06%  2.07%   0 RedEarth Tx Mana

  96   228207340  44591660       5117  0.79%  0.68%  0.68%   0 hpm counter proc

It's a switch not in production yet, so, there are not traffic.

Another curious thing, show proc cpu hist show that cpu is about 20% average with peaks of 100%, but when I telnet the switch, cpu is going down to 8-10 %

IOS version is 12.2(53)SE2, I'm going to upgrade to 10.2.(58)SE2

Yea, I would suggest to upgrade to 122-58.SE2. Once we did that, the CPU dropped to about 10%.

Can you post "dir flash:" ?

I have upgraded the IOS, cpu looks fine. Always is under 8%

Thanks

Anybody have any answers? Still all I can find is that it is for microprocessor communications.

I'm seeing these RedEarth processes take 6-10% of our cpu utilization on L2 access switches.

Can you post "sh ver" and "sh proc cpu sorted"?

It is happening on all of our 3560x and 3750x's, but here is the output from one of them:

Thanks

upgrade a switch to 122-58.SE2, most likely it will solve your problem, then you can apply the new IOS to all other switches.

Please rate useful posts.

Upgrading isn't an option as it is an ios we use globally. I was more just curious as to what the processes are doing...
