Hardware is Ethernet SVI, address is 000 (bia 000) Vlan2 unassigned YES unset administratively down down I tested with this version adventerprisek9 -15.1 with only 2 slot and 4 port each.i did a quick test by creating 3 vlans : sometimes it first XXXX are port and YYYY are slot. Once again it depends on your platform, stack, module, IOS version and the type of port Ethernet, Fast s different from one to another. One part is the slot number and the second part 4 bits are for the port number when you have a fixed number of slot and type( i will explain latter). Sounds interesting to try ? Please try it and give us your feedback, if it's a useful information that can add something to your experience and knowledge!įYKI, it can be tested via Cisco Packet Tracer.Ībout the last Hex XY or lets say last byte is split in 2 part XXXX YYYY. So, the only factor that controls the value of the last 2 characters in the SVI, is the precedence of vlan and it's SVI creation! Regardless the vlan has a higher value (i.e 20) than the first one that you have created which was value 5, even if you would create the new one with lower value (i.e 4) than the first one that you have created it, it would be the same. if you configured one more vlan and make its SVI up, it will get 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! The new Mac address will apply immediately.Actually, you are right, you can get the switch's mac address from these commands, in addition to the command: Disable your network adapter and enable it again. If that entry doesn’t exist, right-click blank area to create a String value with the name NetworkAddress.Ĭlose Registry Editor. Look for the registry entry NetworkAddress in the right pane, and change the value as your new MAC Address. You have to click each subkey to check the DriverDesc value that matches with your network card. You should see several subkeys with names such as 0000, 0001, etc. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\

Method 2: Change MAC Address on Windows 10 / 8 / 7 from Registry Editor You should see the new MAC address show up in the line starting with “ Physical Address“.
To confirm your change, open the Command Prompt and type ipconfig /all and hit Enter. Select the Value radio box and enter your new MAC address.
Within the Property list, scroll down until you find the “ Network Address” or “ Locally Administered Address” property.
