Preparation for the Upgrade

Procedure

1. Obtain system software and store them in the same directory that stores the configuration file on the USB flash drive.
2. Optional: Obtain the HMACs of the system software and configuration file. Skip this step if HMAC check is not required.
   1. Download the HashCalc tool. Install and start it.
   2. Obtain the HMACs as follows:
      

      • Ensure that Key: contains at least three of the following types of characters: upper-case letters, lower-case letters, digits, and special characters (except spaces and question marks) for security.

      • Select SHA256 because FW supports only this type of hash algorithm.

      
      
      

3. Make an index file.
   1. Create a text file named usb.ini.
   2. Copy the following content into the text file and edit fields. For details, see Table 1.

      Table 1 Fields in the index file

      Field	Content
      DEVICENUM	To upgrade the software for only one FW, set DEVICENUM to 1, ESN to the ESN of the FW, and MAC to the MAC address of the FW. To upgrade the software of multiple FWs to the same version, set DEVICENUM to 1, ESN to DEFAULT, and MAC to DEFAULT. To upgrade the software of multiple FWs to different versions, set DEVICENUM to the actual number of FWs to be upgraded and enter the actual values in ESN and MAC.
      SN	Enter the SN, which is the time of the automatic upgrade through USB in the format of YearMonthDate.HourMinuteSecond. For example, when the upgrade time of the FW is 2014-12-28 08:09:10, the SN is 20141228.080910. NOTE: When a USB flash drive storing an index file is inserted into the FW, the FW compares its SN field with the one in the index file and starts automatic upgrade through USB when they are different. After the upgrade succeeds, the FW sets its SN field to the one in the index file to avoid repetitive upgrade.
      RUNMODE	Device running mode: TRADITION: Traditional Modes CLOUD-MANAGE: Cloud Management Modes The cloud management mode and traditional mode differ in presetting user roles. Therefore, if you use a profile of the traditional mode to start a device in cloud management mode, the compare configuration result must be inconsistent. You are advised to run the save command after the startup to save the profile.
      DEVICEn DESCRIPTION	Enter the description about the FW to be upgraded. For example, DEVICE2 DESCRIPTION indicates the description of the second FW to be upgraded. n is an integer ranging from 1 to 100.
      ESN	Enter the ESN of the FW. You can run the display esn command to obtain the ESN of each FW. To match all FWs, enter DEFAULT.
      MAC	Enter the MAC address of interface GigabitEthernet 0/0/0 of the FW. You can run the display interface GigabitEthernet 0/0/0 command to obtain the MAC address. To match all FWs, enter DEFAULT.
      VERSION	Enter the version name. To upgrade the software package, enter the target version name. To upgrade only configurations, enter the current version name.
      DIRECTORY	Enter the path where files are stored on USB. If it is the root directory of USB, enter DEFAULT; otherwise, enter the specific path, such as /test.
      FILENUM	Enter the number of upgrade file types. To upgrade either the system software or configuration file, enter 1; to upgrade both, enter 2.
      TYPEn FILENAMEn HMACn	Enter the system software type and name. For example, to upgrade both the system software and configuration file, enter system-software.bin for the system software and system-config.zip for the configuration file as follows: TYPE1=SYSTEM-SOFTWARE FILENAME1=system-software.bin HMAC1=0ab30a2596bd0f6744631002d941f4218f40e784ae51447ed0bf3a2ff075939a TYPE2=SYSTEM-CONFIG FILENAME2=system-config.zip HMAC2=27dadb18efe4c0cf00268c3d3573a1ea9c270e5c56bfda9dd9bba1d168b5d680 n values in TYPE, FILENAME, and HMAC must be the same.

4. Save the index file.
5. Copy index file usb.ini to the root directory of USB.
