SDM on router

please i am trying to configure my router using sdm. i am connected to the router through console cable. please hope can i do this


Re: SDM on router

The SDM is software, either already installed on the router, or you can d/l it from cisco and install it on your PC.

If it's already installed on your router try the below:-

ip http server

username admin privilege 15 password cisco1234

ip http authentication local

then point your web browser to the router:-


x.x.x.x = IP address of the LAN interface

if the above does not work - follow the instructions on the below web link:-

Re: SDM on router

Please i dont understand why i have to assign ip add to fast interface. I said i am connected to the router through console cable. PLS MY QUES IS,HOW CAN I USE SDM TO CONFIGURE ROUTER CONNECTED TO THE SYSTEM THROUGH CONSOLE .

Re: SDM on router

If you have actually read the URL I sent you:-

http://router_IP_address = HTTP traffic, over the LAN using a IP address.

For example, if the router's IP address is, you would enter the following command:

Step 3 If the username/password dialog is displayed, enter a level 15 username and password to launch SDM. After SDM launches go to Help > About SDM and check the SDM version number. If you have SDM version 1.1 or later, you can let SDM help you update to the latest files by clicking Tools > Update SDM > From Follow the instructions in the displayed screens to update the SDM files on your router.

So - as per the above you have to a a connection to the device via IP over the LAN. The console cable DOES NOT transport any TCP/IP traffic, again if you had actually read the url you would have known this.

I suggest you read the url:-

Again I repeat - you will not/cannot connect to the SDM via the console cable, just so we are perfectly clear you will NEED a LAN connection.

Re: SDM on router

Some routers are pre-configured to start with SDM out of the box (870-series). In that case you need to connect via LAN and use a webbrowser to go the the documented address.

As has been said, the console cable cannot be used to connect using SDM

Re: SDM on router

Good morning justkennie. If you are using the console cable you should be using the command line.

If you want to use SDM from your PC directly to the router then you need to use a cross over cable on your ethernet. Not the console cable or a regular ethernet cable. If you cannot make the cable yourself then order one online or check out Best Buy or Circuit city (I am not sure if they have some but I think I saw some there at one time.

Read the CCNA book for 644-802 by Todd Lammle or thru Cisco. I am sure you will find more info here on this site as well.
