Since Cisco released Cisco IOS version 14 we can now apply and manage the router configuration using a GUI.
By defualt the Cisco SDM GUI is disable, In order to unable the GUI we need to apply a few commands to the router.
To enable the SDM GUI:
Log into the router and type:
Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)# ip http server
Router(config)# ip http secure-server
Router(config)# ip http authentication local end
Router(config)# ip http timeout-policy idle 600 life 86400 requests 10000
The last command will change the defualt user name and password which is cisco for username and cisco for password.
Router(config)# username username privilege 15 secret 0 password
Router(config)# username admin privilege 15 secret 0 newpassword
The last step is to access the router using the web browser:
With Cisco 2800 series pre configured routers we also need to remove the defualt ACL which block access to the router.
