This 01, is not representing the conversion of 5 (as it's vlan 5) to hexadecimal, it's just representing the first SVI you have created in the switch.ģ. Now, you can use the command #show int vlan 5, to get the mac address of the SVI of vlan 5, Then make its SVI up by typing #int vlan 5 You can get now the mac address of the switch itself that is used in the STP election, for example The most interesting that get my attention when you have mentioned the # show int vlan 1, and what I would like to share, that each SVI should get a unique mac address as the default one (vlan 1), and the logic of the switch of giving mac addresses to the created SVI is to change in the last 2 characters of the switch mac address itself, and start addressing by 01, then 02 and so on, each time you create a new vlan and make its SVI up, it will directly give it a mac address according to this logic! Which shows the same mac address that is shown by the other commands! All that’s left is to test your access, reload the switch, and ready the cables.Actually, you are right, you can get the switch's mac address from these commands, in addition to the command: 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.

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.

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.

Run Putty and select the 9600 speed serial connection.

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.
