CONFIGURE A CISCO 2950 SWITCH PASSWORD
Although it is much better to configure an external AAA server (for centralized Authentication Authorization and Accounting), in this article we will just configure a password on each access line (VTY lines for Telnet and Console line):Īccess-switch1(config-line)# password strongtelnetpassĪccess-switch1(config-line)# password strongconsolepass It is a very good security practice to lock-down all access lines of a switch with a password. STEP4: Configure a password for Telnet and Console access The password above will be used to enter into Privileged EXEC mode as described in Step 1 above. STEP3: Configure an administration password (enable secret password)Īccess-switch1(config)# enable secret somestrongpass STEP2: Set up a hostname for the particular switch to distinguish it in the network See Step 3 below about setting up a password for the Privileged EXEC mode. Note: The switch will not ask you for a password when entering into Privileged EXEC mode (i.e after typing “enable”) if it has the default factory configuration. You will get into privileged EXEC mode (“ Switch#”) You will get the initial command prompt “ Switch>”

Use a terminal emulation software such as PuTTY and connect to the console of the switch.
I don’t like graphical GUI or web management at all, so I will show you command line configuration (CLI) which is much more powerful and actually forces the administrators to learn what they are doing on the device. In this article I will describe the basic steps needed to configure and setup a Cisco switch from scratch. Unlike other lower class switch vendors (which are plug-and-play), the Cisco switch needs some initial basic configuration in order to enable management, security and some other important features.

Versatile, reliable, flexible and powerful, the Cisco switch product line (such as the 2960, 3560, 3650, 3850, 4500, 6500, 9400 series etc) offer unparalleled performance and features.Īlthough a Cisco switch is a much simpler network device compared with other devices (such as routers and firewalls for example), many people have difficulties to configure a Cisco Catalyst Switch. In my opinion, the Cisco switches are the best in the market.
