Discovery error

Unanswered Question
Mar 4th, 2009


I have define a new device as Cisco switch 12.2 (6513). The SSH authentication parameters is Ok (username, password and Enable password), I establish connection with Putty and all is correct. But, when i click on "Discover" i always receive this message:

spawn ssh -c 3des -l mars

[email protected]'s password:


Your Local Password:

% Your Local Password: timeout expired!

% Error in authentication.

150-EXCO0001>Error in authentication

I have change the Enable password and i receive the same message.

P.S. The username is define in ACS 4.1 but Enable password is local.

Can you help me ?

Try using a different software to connect to MARS (secureCRT etc.)

Hi Farrukh,

I use Putty only to check the authentication parameters and these parameters is OK. I receive this error message when MARS try to authenticate to the switch 6513.

Do you have a solution 6

I think I misunderstood your original query. I thought you were having problems SSHing into the MARS box itself. It seems that you wan't to add a device in MARS (Switch) which is having a problem, please confirm. Have you tried Telnet, instead of SSH, just to rule out any SSH related issues (like missing key, incorrect cipher/client version etc).

Yes, i want to add a device in MARS (Cisco 6513, Cisco Switch-IOS 12.2). I tried with Telnet but i receive the same error message:

spawn telnet


Connected to (

Escape character is '^]'.

User Access Verification

Username: mars



Your Local Password:

% Your Local Password: timeout expired!

% Error in authentication.

The Enable password is in local mode (into the switch) and the user/ user password is in ACS 4.1 database.
