C8300 / C1100TG SSH Passthrough to console Port

[Steffen Pontiac]

Hi everyone,

we are about to install new C8300(C8300-2N2S-4T2X) and C1100TG(C1100TGX-1N24P32A) and use them as Console Terminal Server and Management Access for OOBM.
Ist it possible to configure them with a passthrough function for Console requests over SSH? I attached a sketch how I liked to connect to the console ports.

For Example:

ssh johndoe@10.10.10.99:2003
.
.
Router123#

Right now it is:

ssh johndoe@10.10.10.99
.
C8300#
C8300#<IP host name>
.
Router123#

I hope I described it clearly

Hello @Steffen Pontiac ,

There is a way to do what you described using the rotary option in IOS which controls the sty line you connect to the router:

line vty 1

 rotary 1

This config enables a new range of ports on the router - 3000+rotary number.

In our example, if you telnet/ssh on port 3001 you will land on vty 1 which is configured with rotary 1.

Now to have a certain vty connect with a specific async line, you can use the "autocommand" command on the vty line:

line vty 1

 rotary 1

 autocommand telnet 10.10.10.99 2003
