[rizwan shaikh]

Hello All,

We are having Cisco 4948E model switches.on one of switches while troubleshooting high cpu I have noticed that show bootflash doesn't show any IOS statistics like total or free space!!

Can anyone give any advice on our future course of action

Hi rizwan shaikh! I Have the same problem too but with WS-C4506-E.

Have you solved the problem ? How ? 

Thank you. 

[Leo Laohoo]

Post the complete output to the command "sh proc cpu sort | ex 0.00".

[Vsevolod Ruchin]

I dont have access to switch right now. Its our customer. 

show process cpu and sh cpu history in attach

[Leo Laohoo]

Thanks for the attachment.  I want to wait until you get access and run the command requested.  :)

[Madhukrishnan Gopinathan Nair]

Dear Riswan,

This is usually due some bad sectors at bootflash. You could try reloading the switch to see if it clears it. But it has a risk associated since the switch may not bootup if it is hardware issue. Also you are seeing lot of parity errors also which gives some evidences of hardware issue.  So please be prepared with a spare switch if you try to reload, since you may need to replace the unit if it fails after reload.

Hope this help.
