Thank you for your help!

I do it yet.but still have this problem.

I have some cisco Switches and Routes,e.g.:cisco 3560,cisco 3825 and cisco 3845.When i added these devices in to the Catci,Cacti says "snmp error".
I don't know what problems. No templates or config problems? Who can help me?
Thank you so much.
