Thanks for the sample. The thing I do not get is, since I am connecting all via console, why the ip addresses and telnet?

Thanks for the link I had read that and still don't get it. This is all console, no telnet, no ip. Maybe that can not be done. This is simply a stack of routers (my test lab) with all of the console ports connected to the 2509 async octo cable and I am connected via console to the 2509.

It can be done.

This type of setup is called "reverse telnet"

in telnet we go from a async terminal to a TCP-based telnet session to the desired target destination.

In reverse telnet we go from a telnet-session to async output - int his case to an async console port on a router.

So in reverse telnet we need an IP address and a port number.

The IP address is simple and is either an Ethernet interface or loopback interface address on the terminal server

The port is a mapping from the line numbers seen by the show line command and takes the form 20xx where xx is the line number.

Thx I'll look into it on Cisco.

the ip is for the terminal server, in your case the 2509.

host --> telnet --> 2509 --> async port whatever --> your other router

you could just use the console on the 2509 if you really want.
