Issues getting a 1941 Term Server to work

bdb_opteman · ‎09-16-2011

Hi,

I set up a terminal server on a Cisco 1941 router. It's very close to working but when I connect to a swith through it, it connects, asks for the username and password, it accepts the password with a password OK message and then nothing further happens.

I'm using the 8 port HWIC and the green Cisco octopus cable to connect to the RJ-45 console port on the remote switch. We have other terminal servers set up in a similar manner and I've looked at Cisco's setup page for doing this.

Any ideas?

Hi Stacey,

When you get a response from the switch, most of the parameters are ok.

However, are you sure the username/passw is not coming from the async line on the 1941?

Lines must be configured with " no login ".

When this is ok, you can try to set the flowcontrol to " hardware ".

Issues like this are very often caused by incorrect flowcontrol settings.

regards,

Leo

Hi Leo,

Sorry it took so long to get back to you. I changed the passwords around and yes, the username/password prompt is coming from the 1941. Even after making sure 'no login' was set under line 0/0/0 0/0/7 in the 1941 router. The strange thing is, even though the prompt is coming from the 1941, when I try to login to a line that isn't connected at the time, I get no prompt. But the username/password I use to make a successful login matches up with whatever username/password I configure on the 1941 so I know it's coming from the router.

I assume when you talk about the lines and no login, you're talking about line 0/0/0, etc on the 1941? I set 'no login' under those lines and verified there was no 'login local'. Is there anything special I need to do to the console lines on the target devices?

I've compared the config with two other terminal servers in the company configured by others and I can't see any big differences.

Perhaps you could post the config of the 1941? Also the output of show line might be helpful in finding some issue.

OK. Here is the config and the show line. I deleted some IP addresses and security information. The menu needs some cleaning up but that's just cosmetic.

I have two comments/suggestions (perhaps a bit related):

- if this is a term server then you would not do slip on the connection to the device. At a minimum I would remove encapsulation slip from lines async0/0/0 through 0/0/7.

- I am not used to seeing lines async configured along with the line configuration of line 0/0/0 0/0/7. Perhaps you might try removing lines async0/0/0 through 0/0/7 and see what happens.

I have not looked at the menu but feel that whatever is there is cosmetic and not related to the problem that you are experiencing.
