A bit a newbie question. I'm running a few 11501's and 11503's, they're all running the following code:

CSS11503# sh ver

Version: sg0810106 (

Flash (Locked):

Flash (Operational):


Licensed Cmd Set(s): Standard Feature Set

Can someone point me to a link/doc/procedure on how I go about upgrading to 8.20 code.

Is it a lengthy procedure ?

Are there any gotchas or tip/tricks I should watch out for ?

Thank you,

On this page, select "Application Networking Software".

On the next page, select "Cisco WebNS (CSS 11500 series)" beneath the heading "Data Center Application Optimization".

On the next page, select "Major, Minor and Maintenance Releases".

On the next page, select "sg0820201.adi-gz".

Then follow the instructions included at the links in the post above.

I also recommend performing a manual upgrade, but you should also perform an automated upgrade to become familiar with this option.
