Objective

Firmware is the program that controls the operations and functionality of the switch. Upgraded firmware may be made available periodically and provides enhanced security, new features, bug fixes or performance upgrades. Backup Specifies that a copy of the file type is to be saved to a file on another device.The article explains how to upgrade the firmware on the ESW2 Series Managed Switches.

Applicable Devices

  • ESW2 Series Managed Switches.

Upgrade/Backup Firmware/Language

Step 1. To Upgrade the firmware , Log in to the web configuration utility and choose Administration > File Management > Upgrade/Backup Firmware/Language. The Upgrade/Backup Firmware/Language page opens:

Step 2. Select the Transfer Method through which you want to proceed. There are three transfer methods available :

  • TFTP
  • HTTP/HTTPS
  • If you selected via SCP

Below are the steps mentioned for different transfer methods available and how to upgrade the firmware using those methods.

Step 3. If you have selected TFTP, enter the parameters as described in this step.

Select one of the following Save Actions:

  • Upgrade Specifies that the file type on the device is to be replaced with a new version of that file type located on a TFTP server.

    Note: The backup action is only allowed through the use of the TFTP transfer method.
     
  • Backup Specifies that a copy of the file type is to be saved to a file on another device.

Enter the following fields:

  • File Type Select the destination file type. Only valid file types are shown. (The file types are described in the Files and File Types section).
  • TFTP Server Definition : Select whether to specify the TFTP server by IP address or domain name.
  • IP Version: Select whether an IPv4 or an IPv6 address is used.
  • IPv6 Address Type: Select the IPv6 address type (if IPv6 is used). The options are:

- Link Local: The IPv6 address uniquely identifies hosts on a single network link. A link local address has a prefix of FE80, is not routable, and can be used for communication only on the local network. Only one link local address is supported. If a link local address exists on the interface,this entry replaces the address in the configuration.

 

Global : The IPv6 address is a global Unicast IPV6 type that is visible and reachable from other networks.

  • Link Local Interface: Select the link local interface (if IPv6 is used) from the list.
  • TFTP Server IP Address/Name: Enter the IP address or the domain name of the TFTP server.
  • (For Upgrade) Source File Name: Enter the name of the source file.
  • (For Backup) Destination File Name: Enter the name of the backup file and then click apply.

Step 4. If you have selected HTTP/HTTPS Method, you can only Upgrade. Enter the parameters as described in this step.

  • File Type: Select one of the following file types:
        - Firmware Image: Select this to upgrade the firmware image.
        - Language: Select this to upgrade the language file.
  • File Name: Click Browse to select a file or enter the path and source file name to be used in the transfer and then click on apply.

Step 5. If you have selected SCP (Over SSH) Method , see SSH Client Authentication for instructions mentioned below.

Remote SSH Server Authentication: To enable SSH server authentication (which is disabled by default), click Edit. This takes you to the SSH Server Authentication page to configure the SSH server, and return to this page.

Use the SSH Server Authentication page to select an SSH user authentication method (password or public/private key), set a username and  password on the device (if the password method is selected), and generate an RSA or DSA key if required.

SSH Client Authentication can be done in one of the following ways:

  • Use SSH Client System Credentials, sets permanent SSH user credentials. Click System Credentials to go to the SSH User Authentication page     where the user/password can be set once for all future use.
     
  • Use SSH Client One-Time Credentials, Enter the following:
      - Username: Enter a username for this copy action.
      - Password:  Enter a password for this copy.

Note : The username and password for one-time credential will not saved in configuration file.

Select one of the following Save Actions:

  • Upgrade: Specifies that the file type on the device is to be replaced with a new version of that file type located on a TFTP server.
  • Backup: Specifies that a copy of the file type is to be saved to a file on another device.

Enter the following fields:

  • File Type: Select the destination file type. Only valid file types are shown. (The file types are described in the Files and File Types section).
  • SCP Server Definition: Select whether to specify the SCP server by IP address or by domain name.
  • IP Version: Select whether an IPv4 or an IPv6 address is used.
  • IPv6 Address Type: Select the IPv6 address type (if used). The options are:

    - Link Local: The IPv6 address uniquely identifies hosts on a single network link. A link local address has a prefix of FE80, is not routable, and can be used for communication only on the local network. Only one link local address is supported. If a link local address exists on the interface, this entry replaces the address in the configuration.

    - Global: The IPv6 address is a global Unicast IPv6 type that is visible and reachable from other networks.
     
  • Link-Local Interface: Select the link local interface from the list.
  • SCP Server IP Address/Name: Enter the IP address or domain name of the SCP server.
  • (For Upgrade) Source File Name: Enter the name of the source file.
  • (For Backup) Destination File Name: Enter the name of the backup file.

Step 6. Click Apply. If the files, passwords and server addresses are correct, one of the following may happen:

  • If SSH server authentication is enabled (in the SSH Server Authentication page), and the SCP server is trusted, the operation succeeds. If the SCP server is not trusted, the operation fails and an error is displayed.
  • If SSH server authentication is not enabled, the operation succeeds for any SCP server.
