2618 switch version upgrade Experiment

2618 switch version upgrade Experiment 1 knowledge Prepare to understand the file system of the switch, and have mastered the configuration methods of layer-3 address 2618. 2. The purpose of this experiment is to learn how to upgrade vswitch 2618 in normal and abnormal situations. 3. In the experiment, the PC connects to the console port of the 2618 switch through a serial port and the service port of 2618 through a network cable. The 2618 switch is upgraded in either normal system or abnormal system. 4. Experiment Device 2618: one PC, one serial port, one network cable, one 5. Experiment topology 6 configuration step 6.1: if the system is normal, upgrade the version. If the switch runs normally before the upgrade, perform the following steps. 1. Use a random configuration line to connect the Console port of the vswitch to the serial port of the background host. Use a network cable to connect an Ethernet port of the vswitch to the network port of the background host to ensure correct connection. 2. Start the layer-3 address on the switch and set the IP address of the background host used for upgrade to the same network segment as the address to ensure that the background host can ping the layer-3 address on the switch. The specific configuration command is as follows: zte (cfg) # set vlan 1 add port 1zte (cfg) # config router // enter the layer-3 configuration mode zte (cfg-router) # set ipport 0 ipaddress 192.168.1.1 255.255.0.0 // set the IP address and mask zte (cfg-router) of layer-3 Port 0) # set ipport 0 vlan 1 // bind VLAN 1zte (cfg-router) to layer-3 Port 0 # set ipport 0 enable // enable Layer-3 Port 01. start the TFTP server software on the background host to configure the TFTP server. 2. Run the version command in global configuration mode on the vswitch to view the current running version. 3. Enter the file system configuration mode, and rename the version with the rename Command. If the upgrade fails, you can switch back to the original version. If the FLASH space is insufficient, you can use the remove command to delete the old version files in FLASH. Zte (cfg) # config tffszte (cfg-tffs) # rename kernel. z kernel. old use the tftp Command for version upgrade. The following command uploads the version file from the TFTP server to FLASH: zte (cfg-tffs) # tftp 192.168.1.102 download kernel. z5. restart the vswitch. Check the running version and confirm whether the upgrade is successful. 6.2 version upgrade when the system is abnormal The following describes the specific steps for upgrading the version when the switch fails to start running normally. 1. Use a random configuration line to connect the Console port of the vswitch to the serial port of the background host. Use a network cable to connect any Ethernet port of the vswitch to the network port of the background host to ensure correct connection. 2. Restart the vswitch and press any key to enter the Boot status under the Super Terminal. 3. Enter <c> In the Boot status and press enter to enter the parameter modification status. Set the Ethernet port address and the TFTP server address. Use the default value for other parameters. Inet on ethernet (e): 10.40.92.106 192.168.1.2 // modify the IP address of the ethernet port to 192.168.1.2host inet (h): 10.40.92.105 192.168.1.1 // change the IP address of the TFTP server to 192.168.1.14. set the backend host address to the same IP address as the preceding TFTP server. 5. The background host starts the TFTP server software to configure tftp for the background host. 6. Enter <zte> In the Boot status to enter the [BootManager] Status of the switch. Enter <?> The command is displayed. [BootManager]:? Ls (list the current directory) del file_name (delete the specified file) tftp ip_address file_name (TFTP upload/download version) update filename (upgrade boot) md filename (create directory) cd absolue-pathname (Change current directory) format (format FLASH) reboot (restart switch) 7. in the [BootManager] status, use the tftp Command to upgrade the version. The following describes how to download a version file from the TFTP server to FLASH: [BootManager]: tftp 192.168.1.1 kernel. z8. in the [BootManager] status, restart the switch using the reboot command. If the vswitch is started normally, run the version command to check whether the new version is running in the memory. If the vswitch cannot be started normally, the version upgrade fails and the operation must start from step 1. 7. Check the version information on version 2618 and the size of the version file, and compare the size and version information of the new version to verify whether the upgrade is successful.
