![]() So for tl dr sake RJ-45 does not mean Ethernet, and Ethernet does not mean RJ-45. I would recommend you start your CCNA path by learning about the Ethernet standard. But, as is true with many things in the computer world what a layman calls something doesn't necessarily translate when you actually start learning about the technology. It has become common to refer to an RJ-45 jack as an Ethernet jack in the same way people refer to an adhesive bandage as a Band-Aid. Moreover, you can use RJ-45 ports for other types of connections, like the serial console port of a Cisco switch, T1 serial connections, and other things. But, you can also do Ethernet over fiber which is obviously a completely different cable and port type. In case, you want us to help you with configuring your switch on Network Configuration Manager's console, you can contact NCM support. You can automate the process by pushing the commands for configuring a switch to multiple devices at one go. For a copper based Ethernet connection it is standard to use an RJ-45 port (but we used to use coax, like your Cable TV or Cablemodem way back in the day). You can use Network Configuration Manager's Configlet feature to configure Cisco switch. Ethernet is not a physical connector, Ethernet is a protocol or standard for transmitting and receiving data. The default password is cisco.Here's a first good lesson for you. Hit Enter on the keyboard to activate the Command Line Interface (CLI). Under the Saves Session s field, enter a name for the settings to be saved as. If you do not wish to save the connection settings, skip to Step 14. (Optional) In order to save the connection settings for future use, go to the Category This chapter describes how to use the switch command-line interface (CLI) to configure the. Recommended method for preventing data overflow is None. The Catalyst 2950 switches are supported by Cisco IOS software. In the Flow Control drop-down menu, select the method of preventing data overflow. Recommended method for detecting errors in transmission is None. In the Parity drop-down menu, select the method of detecting errors in transmission. Stop bit informs the machine that it has reached the end of a byte. In the Stop bits field, enter the number of bits to be sent at the end of every character. In the Data bits field, enter the number of data bits used for each character. For 300 and 500 Series Managed Switches, the speed must be set to 115200. In the Speed (baud) field, enter the digital transmission speed that is compatible with the In the Serial line to connect to field, enter the COM port that your device is connected to. The Options controlling local serial lines page opens: In the Category navigation field, choose Serial. Under the Connection Type field, click the Serial radio button. In this case you would need to use COM4 for the Serial line to make the connection. In the Device Manager, you would look to see what COM port is given to the USB adapter. Right-click on the Windows logo/Start menu and click on Device Manager to open it. If this is the case for you, you need to know where to look to find the correct COM port number when setting up the connection with PuTTY. When plugging that into a computer it assigns a COM port number to it that is not COM1. Newer laptops don’t have Serial ports on them, so in this case you have to use a USB to Serial adapter. An RJ45 Console port resembles an Ethernet port and is labeled CONSOLE on the back of The Cisco DB9 to RJ45 Console Cable also supports console connections, but only if the switch ![]() Connect the switch to the computer using a standard 9-pin serial cable. Do not worry about infecting your Cisco devices via the console session. And certainly, the 2950 is immune to all existing PC-based infiltrations. Sx550X Series | 1.2.7.76 ( Download latest)Īccessing the CLI via PuTTY with a Console Connection Creating a virus that would infiltrate the 2950 - an end-of-life switch - via its console port is something way impractical and useless for anyone to invest the huge effort into.Note: Cisco 200 Series Small Business Managed Switches do not support the CLI. The objective of this document is to show you how to access the Command Line Interface (CLI) of a switch and a Secure Shell (SSH) client. This documentĪssumes you are connecting to the switch using PuTTY. PuTTY is a standard SSH client and can be found here. Recovering an administrator password can only be performed through the CLI. For a user who has had more experience with terminalĬommands, this may be an easier alternative to navigating the web configuration utility. Accessing the CLI allowsĬommands to be entered in a terminal based window. Switches can be accessed and configured through the Command Line Interface (CLI).
