2511 Unable to Connect to Devices

[ehartsocPU]

Hi, i've been searching the support forums and looked at numerous discussions but haven't been able to get my 2511 to connect to other devices via rollover cables. Each device responds differently (which i've included below). Here is my config:

Updated with what works.

Edited with updated config. Still no luck on MX960 or SA2500.

This is fairly old stuff. I tried to find some of the older documents on the subject.

http://www.cisco.com/en/US/docs/ios/11_3/configfun/configuration/guide/fctrmopr.html

http://www.cisco.com/en/US/docs/ios/12_0/dial/configuration/guide/dcmodem.html#wp9362

In the lower one, check the section: Specify Decimal TCP Port Numbers when Connecting to Lines

It has helped me in the past.

The suggestion from Leo about specifying TCP port numbers suggests that there might be an issue with how you have specified the port numbers in your ip host commands. Since most of the devices do work I am not sure that there is a problem in how you are specifying the TCP port numbers. But I do think that it would be good if you could check and verify that the devices that are not working are plugged into the ports specified by your ip host commands.

It also occurs to me to wonder since both devices that are not working are not Cisco devices whether those devices might want their console connections on straight through cables rather than the roll over cables that work so well for Cisco.
