Switch IOS upgrade and backup

First, make sure that the switch to upgrade or back up IOS can communicate with our PC. I. It is recommended that the switch be at our side for tools and notebook settings. Because of this, it is easy to handle problems in the field. Here, we set www.2cto.com Based on the 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. On the other end, can we connect to our laptop? If there is no same interface, we have to use USB to turn it. Remember to install the usb to serial port driver (available on the Internet ), this line will work. Www.2cto.com
After the driver is installed, let's set the speed. Right-click my computer and choose "manage". Then, choose "manage. Click OK. In this way, the physical connection is complete, isn't it fun. 2. Right-click the network neighbor in the notebook IP settings, right-click the local connection, and select Properties. Then, the Local Connection Properties dialog box is displayed, and you can click set. Www.2cto.com
Click OK. Remember to connect the network cable to the electrical port of the switch. 3. Use the secureCRT tool to connect to the vswitch. You can download the Chinese version on the Internet. After installation. Open the secureCRT that has been installed, click the quick connection item, such as the second icon, and then select the protocol, port, and baud rate for the quick connection, and click Connect to connect to the vswitch. 4. for FTP server tool installation, choose 3COM3CDaemon2. 0. For the installation-free Chinese version, open the tool, such as settings. After clicking the FTP server, we select the pop-up dialog box to set the user name and password, user directory, and then click Save User, click OK. In this case, our FTP server is ready. Remember that the laptop IP address is the IP address used to access the FTP server. Www.2cto.com
Next, should we connect to the vswitch settings. Ii. vswitch settings we have just used the secureCRT tool to connect to the vswitch using the Serial protocol. If you press enter, the <H3C> command line management interface is displayed. 1. Set the IP address used to manage VLANs for convenience. Here we use default VLAN 1 as the management VLAN. The default Management vlan of a vswitch is VLAN 1. 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. In this case, OK. III. back up IOS1. view the name of the IOS file to be backed up (if not at this level, you can use quit to back up to this level) <H3C> dir, the s5800_5820x-cmw520-r1211l01.bin is the IOS file we want to back up. With the file to be backed up, we need to use the FTP server for backup now. 2. Connect to the FTP server <H3C> ftp 192.168.1.110 and then ask us to enter the FTP user name and password. This will be done according to what we just set in the 3COM3CDaemon2. 0 Chinese edition without installation.

3. Now we are about to start backing up, such as [ftp] put s5800_5820x-cmw520-r1211l01.bin [ftp] put s5800_5820x-cmw520-r1211l01.bin227 is entering passive mode (191,168, 1,110)
125 using existing data connection 226 closing data connection; file transfer completed successfully. FTP: 27390468 byte (s) sent in 37.765 second (s), 725.00 Kbyte (s)/sec. [ftp] is the spare parts completed now? www.2cto.com
4. Check the backup result. Open the FTP user directory of the notebook, find the file with the same file name as we just backed up, check whether the big word is consistent, and whether the creation date is consistent with our current time. This completes the backup. 4. After the IOS upgrade and backup are completed, should we play with the upgrade? Because sometimes the version is too old to affect the use, it must be upgraded. Now we will use the backup steps to complete the upgrade. If the switch is normal, the upgrade is simple. Www.2cto.com
1. First, let's see if there is no space to store new IOS <H3C> dir2. if there is not enough storage space, we will delete redundant or existing IOS ones. <H3C> delete/u s5800_5820x-cmw520-r1211l01.bin input Y will be completely deleted. With the space available, we start to access FTP. 3. Start FTP upgrade. The file name here is based on the IOS file name in the FTP user directory. Remember to complete the suffix. [Ftp] get s5800_5820x-cmw520-r1211l01.bin www.2cto.com
After the transfer is complete, we will exit FTP [ftp] quit4. then we will set the IOS for the reboot. <H3C> boot-loader file flash:/s5800_5820x-cmw520-r1211l01.bin slot 1 main5. set up, we should restart the device to experience the new IOS. <H3C> In reboot, the first one is input N without saving the existing configuration, and the second one is input Y to restart the device.
