Router to Switch (Serial to RJ45) connection. Is this possible?

[vimukthilk]

Please forgive me if this is a dumb question!

I am trying to find a way to setup the following:

Router A's WIC-2T serial port S0/1 --> Switch RJ45 ethernet port Fa0/1

Switch RJ45 ethernet port Fa0/2 --> Router B's WIC-2T serial port S0/1

Is this even possible? I understand that with a serial connection one end is the DCE and the other DTE. If this setup is possible, how would I configure this? Are there adapters available for this?

Thank you very much in advance.

Kind regards,

Vim.

It's called "reverse" telnet and it's possible.

No, it is not possible.

You cannot connect serial ports to ethernet ports. That is the basic of networking.

To connect a router to a switch, ONLY use ethernet interface, without ANY adapter.

Whoopsie.

I misread the post.  I thought it was from router AUX to the console port of the switch.  Mea culpa.

Just go back and edit

Not fair to everyone Paolo.  I'm happy to apologize for mistakes I've made.

Thank you to both of you.

I understand that you cannot physically connect a serial cable to an ethernet interface. I was wondering if anyone knew of any adapters that would interface between a serial and ethernet cable to facilitate this. By the look of things, technology is not quite there yet.

Thanks for your input.

That "technology" (connecting different media types together), is called a router.

Thanks Paolo, that's an interesting point of view.

It's a fact, not an opinion.
