Hi i just got a laptop .. how I will connect it to 2511.. there is no serial port.. can I use a telnet or something else.. Thanks
This seems to be a quite different question from what I thought at first. Sorry if I did not understand it well.
What I now think I understand is that it is not a question about the 2511 but is a question about accessing routers and switches through their console ports when there is not a traditional serial/console port on the laptop. This is actually a fairly frequent thing these days with many new PCs (especially laptops) not having the traditional serial/console port. Frequently the answer to this is a USB to serial adapter. There are a number of them on the market. I have heard good things about the adapter from Belkin. I do not have personal experience with this since I managed to find a laptop with a serial port when I got my current laptop (a couple of years ago).
So I believe that the answer to your situation is to get a USB adapter for console/serial communication.
