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. Important:- As said earlier Telnet sends commands and passwords in plaintext over the network.In my opinion, the Cisco switches are the best in the market. Go to your system and telnet to the router/switch PC>telnet 10.0.0.1
If you haven’t configured VLAN just enter 1, as for the IP address it should be in the same subnet as the Telnet client and the IP address should be unique i.e., it should NOT be assigned to any other host on the network. When you configure the VLAN interface enter the VLAN number in which the TELNET CLIENT (this is the system FROM which you will execute the telnet command) is located. Replace the word password in the “enable secret” command to your preferred privilege mode password, also replace telnetpw with your telnet password. Switch(config)#service password-encryption Switches being Layer 2 devices do not have any IP addresses assigned by default, so we’ll assign an IP address to a VLAN interface which I’ll show you how.
To Configure Switches for telnet access we use the same commands as seen above with one addition. Configuring Cisco Switches for Telnet access The “service password-encryption” stores the telnet password in encrypted format. Similarly after the “line vty” command replace telnetpw with your telnet password. Replace the word password with your strong password. If you already have a privilege mode password set ignore the command. The command enable secret sets a privilege mode password and stores it in an encrypted format so that it isn’t visible when viewing the running configuration. Router(config)#service password-encryption Configuring Cisco Routers for Telnet accessĪssuming you’ve configured the interface IP address settings properly just entering the following commands will configure your cisco router for telnet access. Take note that Telnet sends commands as plaintext over the network so don’t use telnet this unless you’re on a testing environment or 101% sure your network is safe from intruders. Lets start with some info about the Telnet protocol – Telnet uses port 23, this protocol is used for remote administration of devices through commands.
