What command can show image and space info in WLC5500?

[wfqk]

Hi Cisco router has some command show flash or dir etc to show free space and image size. I'd like to know if there are some relative commands in WLC? Thank you

Hi

 It doesn't and you don't to worry about disk space on WLC.

 I never see a problem related with disk space.

 If you want to know the size of image you can look at Cisco website on the download page.

 Cisco WLC is well served with RAM memory and disk space. 

 As it does not hold logs, so, nothing to worry about. Probably Cisco TAC might have some hidden command just in case.

-If I helped you somehow, please, rate it as useful.-

Very good stuff. Some of this commands require more privileges then the local admin has, but, most of them can be applied.

 Is there a command do walk through the SO directories like the 'shell' command on Prime ? 

Thank you.

[Saravanan Lakshmanan]

Regards shell/devshell access to WLC were there in past for internal access only and removed lately considering security issues/vulnerabilities. We've equivalent external commands these days on critical cases to manage/contain.

[wfqk]

It is very helpful. Thank you all!

[davinci]

what is the impact for test system dir command?  Will this cause any issues with memory or processor utilization?
