From the website i got this info:
SDM (Security Device Manager) allows you to configure and manage your router via the use of a GUI. Please find the steps below :
1)Download the SDM-Vxx.zip file from Cisco's website.
2)Ensure that you have the sdmconfig*.cfg file within your routers flash for your version of router. You can confirm this by using the command `show flash`.
1) I tried to find SDM from cisco website but unable to find SDM, where I can download this file?
2) from the info (website) i did not see any file that resemble sdmconfig*.cfg see the attachment , why should I do?
