Installing SDM 2.5 on cisco 2600


Guys i am new to the cisco world.

I am trying to configure SDM 2.5 on a cisco 2600.

I have access via telnet to the router and was able to change the enable password - which i think is level 15 (right?) and setup (and bring up) the ip on the ethernet interface. I can ping - and get response from - the router

Trying to install SDM on the router i need to provide the default username i tried both admin/administrator but SDM can't communicate with the router

Any ideas or shuggestions would be highly appriciated.

Good morning  Ran Bendori

thanks for using our forum

In order  to enable SDM, follow this steps in the router configuration.

1. Assign an IP address to the router:   ip address x.x.x.x y.y.y.y

2. Create a username:                ( username privilege 15 password 0 )

3. Enable Http server:               ( Ip http server)

4. Enable Http secure-server :   (Ip http secure-server )

5. Enable local authentication : (ip http authentication local)

6. Set a enable password :          ( Enable secret cisco)

7. Enable local Authentication : ( Line vty 0 15

                                                       Login local

                                                       privilege level 15

                                                       transport input telnet
                                                        transport input telnet ssh )

Then  to access the SDM, you have to access from the bowser and enter the router's IP

I hope you find this answer useful, if it was satisfactory  for you, please mark the question as Answered.

I have done all that,  But SDM 2.5 will not install on my Router.

Where can i find a list of hardware requierments ?


hi Ran Bendori

You don't have to install the SDM in your router, you have to install it in your pc, then run the program

Hi Ran,

Could you post show run? Default router user/password is usually cisco/cisco.

I would agree with Johnatan to run SDM locally on PC since a 2600 router usually has limited memory resources.

Make sure you've got Java installed (usually older version works) when running SDM.

For some reason, even though i assigned an internal IP to the f0/0 i can't ping.

the router is connected of course. Show Run Below

hi ran,

you've got some missing command lines for SDM to work. try following Johnnatan's advice or use this URL:

conf t

username privilege 15 secret 0

ip http server

ip http authentication local

make sure your PC and the 2600 FE0/0 are on the same subnet. do a ping to verify network connectivity.

I failed with two things.

1. Setup a level 15 username and address

Bagira#conf t

Enter configuration commands, one per line.  End with CNTL/Z.

Bagira(config)#username admin privilege 15 secret 0 password


% Invalid input detected at '^' marker.

2. setup an http secure server (http is running)

Bagira#conf t

Enter configuration commands, one per line.  End with CNTL/Z.

Bagira(config)#ip http secure-server


% Invalid input detected at '^' marker.

I can ping the router, the cable was diconnected

any idea ?
