I. It is recommended that switches be powered on and configured in non-service environments for tools and laptops to avoid unnecessary impact on normal services. Here, we set a vswitch without any configuration. 1. after the physical connection switch control port and nic switch are powered on, we connect the CONSOLE data line of the switch to the CONSOLE port of the switch, find the root direct connection network cable, and connect our notebook to the switch, you only need to be able to communicate with the vswitch.

Note: The red font must be manually entered. Go to management VLAN 1 [H3C] interface Vlan-interface 1 to set the management IP address to 192.168.1.101 [H3C-Vlan-interface1] ip add 192.168.1.101 255.255.255.0 because all the default ports belong to VLAN 1, so we do not need to change the remaining. In this case, we can PING the switch on the laptop to see if the switch is accessible. Www.2cto.com

The file name must be changed to config. cfg. Remember to complete the suffix. [Ftp] get config. IPv6. if the upload is normal, you can check that the file you just uploaded is the same as the file size in our FTP directory. After the transfer is complete, we need to exit FTP [ftp] quit7. restart the device (remember to choose N if you are prompted to save the existing configuration) 3. Restart the device and enter the vswitch to check whether the configuration is consistent with the original script. You can use a file comparison tool for comparison. 1. file comparison method: 2.
