Reverse telnet to HWIC-16A async interfaces

carlosv · ‎07-11-2007

Hi,

I have a 2821 with an HWIC-16A on slot 0 and a WIC-1AM-V2 on slot 1. The async interfaces are numbered from Async 0/0/0 to Async 0/0/15 and are connected to other routers consoles for management.

What I need to know is which range should I use to perform reverse telnet on this ports. 2010 to 2025?? I've searched everywhere and I can?t find a definitve answer.

Thanks In advance

Carlos

Hi,

First check the output of show line command.

The first row is for console. It is always with the lowest number (0) followed by the async lines. The number of async lines varies by platform being used. The reverse telnet ports between 2000-2999 (ascii mode) and 6000-6999 (binary mode) range. The above command output will show the TTY line numbers being used and you have to add that number to 2000 and 6000 for example the first TTY line is 33 its reverse telnet port will be 2033 and 6033.

Hope it helps rate if does,
