Cisco 2611 Terminal Server


I have one of the 16 spider cables from my 2611 Terminal Server plugged into a console port of a device that exists behind the firewall. But, it does not appear to be working.

Config of 2611 Terminal Server below and output of show line when an attempt is made to connect the remote cisco router. I already have this solution working for other routers and all works.

Config of line 33 48 on terminal server:-

Re: Cisco 2611 Terminal Server


I wonder about this line of output:

Status: Ready, Connected, Active

and wonder what happens if you issue the command clear line 41 from privilege mode of the terminal server?

The output shows that it has been used 15 times. Has it worked before or has it ALWAYS failed?

If you remove the terminal server cable and connect directly to the router console port with a PC does it work?

If you connect a different cable from the terminal server to the router and attempt access with the different reverse telnet port does it work?

If you can provide answers to these we might be closer to having answers to your issue.
