Configure Console Ports On Catalyst Switch

[Rem Markov]

Hey there everyone!

So We received new Cisco C8300-2N2S-4T2X with `16 port Async Serial NIM` module.

While trying to use the Asyncs I have simply did:

` telnet <switch IP> <2000 + line number> ` 

And then simply login, Now trying to SSH, I'm failing.
`ssh <switch IP> <2000 + line number>` - `Line has invalid autocommand "2002"`

However I looked everywhere and I find 0 blogs or whitesheets that help me configure this,
Is someone here familiar with this topic?

Hello @Rem Markov ,

terminal server configurations are usually supposed to work with telnet at <2000+n>  port

You can SSH to the terminal server but then you use reverse telnet to access each async serial line.

The error message tells that 2002 is not taken as TCP port to be used fo SSH session you would like to start but it is passed to the line as a command ( auto command)

Hope to help

Giuseppe
