Preparations for the Upgrade

1. Prepare the upgrade tools, including the operation terminal PC, Ethernet cable, and serial cable.

2. Obtaining the Target System Software
   • Enterprise users: Log in to https://support.huawei.com/e, enter the switch model in the search box, and click the path that is automatically displayed below the search box to enter the product page. On the page that is displayed, click Software Download and select the version. On the Version and Patch tab page, obtain the system software (.cc) required for the upgrade.
   • Carrier users: Log in to https://support.huawei.com, enter the switch model in the search box, and click the path that is automatically displayed below the search box to enter the product page. On the page that is displayed, click Software, select a version in the VxxxRxxxCxx or VxxxRxxxCxxSPCxxx format, go to the corresponding version path, and obtain the system software (.cc) required for the upgrade.
3. Obtaining the Patch File of the Target System Software
   • Enterprise users: Log in to https://support.huawei.com/e, enter the switch model in the search box, and click the path that is automatically displayed below the search box to enter the product page. On the page that is displayed, click Software Download, select a version, and click the path under the Public Patch in V and R Version tab to obtain the patch file (.pat) required for the upgrade.
   • Carrier users: Log in to https://support.huawei.com, enter the switch model in the search box, and click the path that is automatically displayed below the search box to enter the product page. On the page that is displayed, click Software, select a version in VxxxRxxxSPHxxx format, go to the corresponding version path, and obtain the patch file (.pat) required for the upgrade.

4. Enable the FTP server function on the PC.

   • Most laptops do not provide COM ports and can only be connected to devices through USB ports. In this case, you need to purchase a USB-serial cable, directly connect the COM female connector to the COM male connector of the console communication cable delivered with the device, and connect the USB port of the device to that of the PC. Then install the driver delivered with the USB-serial cable on the PC or download a USB-to-RS232 driver from the Internet.

   • A device that supports the MiniUSB interface can use a MiniUSB B cable to connect the MiniUSB port on the switch to the USB port on the laptop. Select a proper driver based on the device model before installation. (The mini USB driver supports only Windows Vista and Windows 7 operating systems)

     To obtain the mini USB driver, visit http://support.huawei.com/enterprise and download Switch-MiniUSB-driver.00X.zip in the corresponding path based on the product model and version.

Establishing the Upgrade Environment in FTP Mode

1. Connect the switch to the PC using a console communication cable and Ethernet cable to establish the networking. As shown in Figure 3-24, connect the console communication cable to the console port of the switch and connect the Ethernet cable to any Ethernet port. (GigabitEthernet 0/0/1 is used as an example here.)

   Figure 3-24 Networking diagram for upgrading a new device
   

2. Start the terminal emulation software on your PC, create a connection, select the connected COM port, and set communication parameters. Communication parameter settings on the terminal emulation software must be the same as the default settings on the switch, which are: 9600 bit/s baud rate, 8 data bits, 1 stop bit, no parity check, and no flow control.

3. Enter the user name and password.

   The default username and password are available in S Series Switches Default Usernames and Passwords (Enterprise Network or Carrier). If you have not obtained the access permission of the document, see Help on the website to find out how to obtain it.

4. Configure a management IP address for the switch to make the switch and PC reside on the same network segment, so that the switch and PC can ping each other.

   <HUAWEI> system-view 
   [HUAWEI] interface vlanif 1
   [HUAWEI-vlanif1] ip address 10.10.1.1 24    //10.10.1.1/24 is the IP address configured for the VLANIF interface. You can configure the interface IP address based on the actual situation. Ensure that the interface IP address is on the same network segment as the PC.
   [HUAWEI-vlanif1] quit 
   

Version Upgrade Operations

1. Configure the switch as an FTP client to transmit files between the FTP server and the PC.

   <HUAWEI> ftp 10.10.1.2    //10.10.1.2 is the IP address of the terminal PC.
   [ftp] get S5720-HI-V200R010C00SPC600.cc    //Load the system software to the switch. S5720-HI-V200R010C00SPC600.cc is the file name of the system software.
   [ftp] get S5720-HI-V200R010SPH013.pat    //Load the patch file to the switch. S5720-HI-V200R010SPH013.pat is the file name of the system patch.

2. Check whether the system software and patch file are successfully loaded.

   <HUAWEI> dir flash:    //Check whether the size of the loaded file is the same as that of the file on the PC. If not, delete the file and load it again.
   Directory of flash:/                                                            
                                                                                   
     Idx  Attr     Size(Byte)  Date        Time       FileName                     
       0  -rw-    106,395,444  Jul 22 2017 23:44:18   S5720-HI-V200R010C00SPC600.cc
       1  -rw-          84210  Jun 28 2017 05:16:29   S5720-HI-V200R010SPH013.pat
       2  drw-              -  Jan 01 2017 00:00:44   dhcp                         
       3  drw-              -  Dec 03 2013 09:22:27   user                         
       4  -rw-         13,432  Jan 01 2017 00:00:45   default_ca.cer            

3. Specify the system software and patch for next startup of the switch.

   <HUAWEI> startup system-software S5720-HI-V200R010C00SPC600.cc    //Set the system software for next startup.
   <HUAWEI> startup patch S5720-HI-V200R010SPH013.pat    //Set the patch for next startup.

4. Check the configuration for next startup.

   <HUAWEI> display startup  
    MainBoard:
     Configured startup system software:        flash:/defaultdevicesoft.cc
     Startup system software:                   flash:/defaultdevicesoft.cc
     Next startup system software:              flash:/S5720-HI-V200R010C00SPC600.cc
     Startup saved-configuration file:          flash:/vrpcfg.zip
     Next startup saved-configuration file:     flash:/vrpcfg.zip
     Startup paf file:                          default
     Next startup paf file:                     default
     Startup license file:                      default
     Next startup license file:                 default
     Startup patch package:                     flash:/patch.pat
     Next startup patch package:                flash:/S5720-HI-V200R010SPH013.pat

5. Restart the switch.

   <HUAWEI> reboot fast                                                             
   Info: If want to reboot with saving diagnostic information, input 'N' and then e
   xecute 'reboot save diagnostic-information'.                                    
   System will reboot! Continue?[Y/N]: y                                         

If the system software of the switch is damaged and you cannot restart the switch, you can use the BootLoad program to modify the system software, configuration files, and patch files, and configure the switch to start with the specified files. This implements the system software restoration and rollback of the switch. For detailed operations, see Configuration Guide - Basic Configuration Guide - BootLoad Menu Operation.

Verifying the Upgrade

After the switch is restarted, check whether the upgrade succeeds following Table 3-6.
