How to setup cisco 2511

After figuring ouch which ports are going to go to which device we can start generating a configuration. Now we can move on to our host configuration. The first thing you need to know is how to connect to your devices, right?

To get back to your access server, use the Cisco escape sequence. Use the command show sessions to see which lines are open, to clear them simply type clear line [line number]. You can also use the command disconnect [session number] to clear any open sessions. If you simply wish to switch back to that session, just type the connection number at left displayed in the show sessions output.

Pressing enter on an empty line also resumes your most recent session. Network engineer turned management currently servicing the enterprise data center market.

Such a modem eliminates the need to configure a dial backup for each device. The terminal server is connected through its async ports to the console ports of the other devices. Use the ip default gateway statement, and point to the the next hop router on the Internet.

This command enables you to have connectivity to the terminal server through the Internet even if routing is not enabled. In this section, you are presented with the information to configure the features described in this document. The name field need not match the actual name of the router to which you want to connect.

However, ensure that you enter a name you would want to use in the reverse Telnet. When you use this command and the name field, you do not have to know the actual port number of the remote device. In our example configuration, we use the loopback IP address. In this case, the port becomes unusable for incoming connections. Note: In our configuration example, the async lines use the minimum configuration of the transport input telnet command.

So you can Telnet to the devices on the async line. Host can be one of the name fields defined in the ip host command.

The Telnet router port decimal 23 on the host is the default decimal TCP port number. Line numbers range from in our configuration. Use the show line EXEC command to view the available lines. Enter the session conn number to connect to the corresponding device. For example, to connect to type 1 , which is the connection number.

However if you hit the return key, you are connected to the current terminal session, which in this case is router Note: Ensure that you can reliably issue the escape sequence to suspend a Telnet session. Some terminal emulator packages are unable to send the correct sequence, Ctrl-Shift-6 then x. If you cannot connect to the router of your choice with a name configured in the ip host command check:. The output of the show ip interface brief command provides this information. Cisco recommends you to use loopbacks because they are always up.

Ensure that you have the correct type of cabling. For example, you must not use a crossover cable to extend the length. Refer to the Cabling section for more information. Establish a Telnet connection to the IP address port to test direct connectivity.

You must telnet from both an external device and the terminal server. For example, telnet
