To connect to Cisco Router or Cisco Switch using SSH from a Windows workstation, you must use a SSH client tool (SSH client utility is not packed with Windows Operating Systems up to Windows 7).ĥ. Disabling telnet will prevent someone to connect to a Cisco Router or Switch accidentally using telnet and cause a security issue.Ĥ. Next important step you have to do is to configure router/switch to use local user database for authentication and to disable telnet. Before generating RSA encryption keys, you must change the default hostname of a Cisco Router or Switch.ģ. Cisco devices use RSA public key encryption algorithm for SSH connectivity. First step in configuring SSH to securely access the CLI interface of a Cisco Router or Switch remotely is to create a local user database for user authentication.Ģ. All that’s left is to test your access, reload the switch, and ready the cables.How to configure Cisco Router/Switch to enable SSH (SecureĢ hours ago 1. You’ve made it through the learning process with (hopefully) minimum bumps and bruises, and you’re just about ready to ride off. You can now try to log in from a remote machine to verify that you can ssh to your Cisco switch. Verify SSH access by typing ‘sh ip ssh’ to confirm that the SSH is enabled. Make sure that the password-encryption service is activated.
#Cisco switch configuration password#
Then, set the privilege exec password with username name privilege 15 secret password. Set the enable password using the enable secret password command. If you have not set the console line yet, you can easily input these values:

Choosing a key modulus greater than 512 may take a few minutes. Step 6: Configure access portsĪfter already performing basic network switch configurations, it’s time to generate RSA keys to be used during the SSH process, using the crypto commands shown here:Ĭhoose the size of the key modulus in the range of 360 to 2048 for your General Purpose Keys. It means there is no other encapsulation supported so there is no need for an encapsulation command. If not, simply type switchport mode trunk. If ISL is supported, you have to issue the switchport trunk encapsulation dot1q on the trunk port configuration. You might already have a template ready for access port configuration, but in case you don’t, here are some commands you should use: Step 5: Configure trunk portsĮnter the command sh int g0/1 capabilities and check the trunking protocol supported. To easily reset the domain back to zero, change the config mode to transparent: Step 4: Configure access ports So, before you add your switch to the network, you’re going to want to set its revision number to zero.
#Cisco switch configuration update#
This means that the switches will update their VLAN configuration based on the VTP information being sent by the switch with the highest revision number. Your switch will only process data from a neighboring switch coming from the same domain and if the revision number of the neighboring switch is higher than its own. When you set a VTP domain name, the revision number is set to zero-after which each change to the VLAN database increases the revision number by one. The VTP revision numbers determine which updates are to be used in a VTP domain. Hit the show vtp status command to reveal your Virtual Trunking Protocol (VTP) revision numbers. Next, make sure your switch has a set hostname and domain name: Step 3: Check VTP revision number Follow any preset naming assignment your company is using and then assign an IP address on the management VLAN.

Unlike with that punny name you gave your home Wi-Fi network, when setting up the hostname for your switch you should probably stick to a more professional and standard naming convention. % Generating 1024 bit RSA keys, keys will be non-exportable.įor spare switches, make sure to delete the flash:vlan.dat file to erase the previous configuration.Switch01(config)# crypto key generate rsa.You are now connected to the switch and ready to check the output of the following commands:
#Cisco switch configuration serial#
Run Putty and select the 9600 speed serial connection.
#Cisco switch configuration install#
To do this, you will need to download and install Putty (or a similar, fun-named software tool). Next, use a rollover cable to console into the switch from your computer.

If everything checks out, power on the switch and verify that all the indicator lights are in working order. Or, if you are using a spare, check the device hardware and its connected cables for any damages. Check the model number of your shiny new switch.
