Introduction

This article describes how to update the firmware on Arista Access Points via the On-Premises Wireless Manager server.

  • On the Arista Cognitive WiFi Cloud, the AP firmware update bundle will be available via the cloud. CloudVision WiFi or the Wireless Manager UI will indicate if new firmware is available for any APs and you can initiate the firmware update for these devices from the UI.
  • If you are using an on-premises Wireless Manager server with Internet connectivity, that is configured to sync with the cloud firmware repository, the update bundle will be available on Wireless Manager itself, after it has synced with the firmware repository in the cloud. CloudVision WiFi or the Wireless Manager UI will indicate if new firmware is available for any APs and you can initiate the firmware update for these devices from the UI.
  • If you are using an on-premises Wireless Manager server with no Internet connectivity, or if the server is configured with the sync mode set to LOCAL, then you must manually update the Wireless Manager server with the AP firmware update bundles and capability information.

    The latest firmware update bundles for Arista APs are available at the WiFi Downloads section on the Customer Portal.

Solution

To verify the sync mode of on-premises Wireless Manager, please execute the following command on the config shell CLI

get device repo config

The output indicates the status of the sync mode for the firmware and device capability repositories in the cloud.

Sync modes:

  • LOCAL = Wireless Manager will not sync with the cloud firmware repository and an administrator must download the upgrade bundles and capability files to make Wireless Manager aware of the latest firmware.
  • REMOTE = Wireless Manager will sync with the cloud firmware repository to download the upgrade bundles and capability files. This will work for on-premises servers only when Internet connectivity is established with the external repository (devices.mojonetworks.com).

Uploading Device Firmware Bundles on Wireless Manager

Perform the following steps to update the device firmware bundle on a Wireless Manager server that is not connected to the Internet:

  1. Download the appropriate .tgz file and the corresponding .md5 file from the WiFi Customer Portal. The file name will include the release number.
  2. These files must be hosted on a server from where Wireless Manager can download them over HTTP, FTP, SFTP, or SCP.
  3. To upload the firmware bundles on Wireless Manager, run the following command on the config shell CLI
    set device upgrade bundles

  4. The command prompts for the following information:
    Option Description
    Operation to perform Type U to upload the firmware bundle.
    Method to download Which method Wireless Manager must use to connect to the remote server and download the firmware bundle.
    IP Address /DNS Name IP address or the DNS name of the remote server where you have hosted the firmware bundle.
    Login Name Login name to connect to the remote server.
    Login Password Corresponding password.
    Upgrade Bundle File Path The path on the remote server where the firmware bundle files are placed. Ensure that both the .tgz file and the corresponding .md5 file are at the same location.
  5. Enter y to confirm that the firmware bundle must be downloaded from the remote server on to the Wireless Manager server.
  6. Enter y to confirm the version information.

After these steps have been completed, AP firmware update can be initiated via the Wireless Manager or CloudVision WiFi UI.

Important! You must also update the device capability information on the Wireless Manager. Refer to the instructions in the next section.

Table 1: Device Capability Information for On-Premise Servers

Server has Internet connectivity? Server Version Device has Internet connectivity? How to manage Capability?
No

 

All server versions, 8.1.1 and later Yes and No, both cases You must manually upload the Capability information on the server using config CLI.

Please download the capability information file from the corresponding AP model folder on the WiFi Customer Portal.

Yes

 

8.3 or later

 

Yes and No, both cases Server will automatically download capability information from external repository. No manual action is required.
Yes

 

8.1.1 and later but Pre-8.3

 

Yes

 

Server will automatically download capability information from external repository. No manual action is required.
Yes

 

8.1.1 and later but Pre-8.3

 

No

 

Server will automatically download capability information from external repository. No manual action is required.

Updating Device Capability Information on Wireless Manager

Perform the following steps to update the device capability information if the Wireless Manager server does not have Internet connectivity:

  1. Download the capability_master.db and capability_master.db.md5 files for the respective AP model.
  2. These files must be hosted on a server from where Wireless Manager can download them over HTTP, FTP, SFTP, or SCP.
  3. Check the repository sync mode by running the following command on the Wireless Manager config shell CLI
    get device repo config

  4. If the repository sync mode is set to REMOTE, perform the next steps. If the sync mode is set to LOCAL, proceed directly to step 10.
  5. Change the repository sync mode with the following command.
    set device repo config

  6. Enter y to change the upgrade bundle repository sync mode.
  7. Enter LOCAL.
  8. Enter y to change the capability repository sync mode.
  9. Enter LOCAL.
  10. Run the command
    set device capability
  11. The command prompts for the following information:
    Option Description
    Method to download Which method Wireless Manager must use to connect to the remote server and download the capability files.
    IP Address /DNS Name IP address or the DNS name of the remote server where you have hosted the capability files.
    Login Name Login name to connect to the remote server.
    Login Password Corresponding password.
    Capability File Path The path on the remote server where the capability files are placed. Ensure that both the capability_master.db file and the capability_master.db.md5 file are at the same location.
  12. Enter y to confirm that the capability files must be downloaded from the remote server on to Wireless Manager.

Wireless Manager now has the new capability information for the selected AP model.
