Use the following workflow to activate High Availability on a pair of newly installed devices. The workflow includes setting each device's local and remote HA interface addresses and installing the single HA license that applies to both devices.

Refer to High Availability for an overview of the feature and a summary of the corresponding HA user interface changes. Refer to Workflow for Initial Setup - High Availability for the complete installation and configuration instructions.

Prerequisites 

  • Login access at each device to the  webUI as user administrator (admin).
  • Completion of the Workflow for Initial Setup - High Availability up to this point in the workflow.
  • A Node-Locked License (NLL) for HA deployment uploaded to the Active device. Note that generating the license file in Salesforce requires the IDs of both devices. Refer to Obtaining and Installing an SBC SWe Edge Production Node-Locked License. 
  • Ethernet interfaces defined or reserved for the  function, as follows:
    SBC Ethernet Interface TypeCharacteristics
    High Availability

    Each device has a dedicated  HA interface, High Availability.

    When you enable HA for a device, you assign a local IP address that serves as the device's base HA IP address. From that, the system automatically assigns three IP addresses to support the device's HA interface. 

    Note

    The base HA IP addresses of the two devices must be static IPv4 addresses on the same subnet and at least three addresses apart. Example: 10.10.10.41 and 10.10.10.44. 

    Here is an example of the IP address assignments for a pair of devices after HA has been enabled on both devices:

    IP AddressPurposeExample:

    base IP address +2Configuration sync210.10.10.4310.10.10.46
        • 1 Overrides any assignment made in the Setup Wizard.
        • 2 Not viewable or configurable to the user from the webUI.

    Media (packet)

    Each device has SWe Edge media (packet) interfaces, Ethernet 1 and Ethernet 3. 

    You will assign unique, static IP addresses to the media interfaces later, after you have enabled HA on the two devices. Refer to Workflow for Initial Setup - High Availability. (The SWe Edge settings replicate automatically to the Standby device in real-time when you configure the Active device.)


HA Deployment Example

Workflow

Step

Action

1Enable High Availability on Active and Standby Devices
2Verify High Availability Status
3Install an HA License

Enable High Availability on Active and Standby Devices

Enter the local and remote HA interface IP addresses of the first High Availability device, then allow the device to reboot. Repeat the steps for the other device. 

Note

In the following procedure, to "Log in to your instance" means to log in to the webUI.

Attention

When assigning local and remote IP addresses, they must be static IPv4 addresses on the same subnet and at least three addresses apart. Example: 10.10.10.41 and 10.10.10.44.

Start

  1. Log in to your SBC SWe Edge instance. 
  2. Click the Settings tab at the top of the WebUI.
  3. In the left navigation pane, go to System > Node-level Settings.
  4. Click Enable HA.

    Enable HA on SBC SWe Edge Instance


  5. Enter the Local IP Address, Local IP Netmask, and Remote IP Address in the Create HA Interface pop-up window. 

    Note

    The Local IP is the HA IP address of the instance you are currently logged in. The Remote IP is the other HA IP address of the other instance, as mentioned in the the Prerequisites section. 


    Create HA Interface on the Instance


  6. Click OK. The following message opens.


  7. Click OK. The following message opens.

    Note

    It takes about 2 minutes for the instance to reboot. The system takes you back to the log in page once the reboot is complete.

  8. Log in to your SBC SWe Edge instance.
  9. Click the Settings tab at the top of the WebUI.
  10. In the left navigation pane, go to Networking Interfaces > Logical Interfaces.
    (In the Edge 8000 webUI, go to SBC > Networking Interfaces > Logical Interfaces.)

    HA Interface on the Active Instance


  11. Confirm that HA is enabled on this instance. The HA role of the instance is seen at the top right hand corner of the WebUI.

  12. Repeat steps 1 to 11 in the second instance, which will become the Standby.

Verify High Availability Status

Check the High Availability status to ensure that both devices, referred to as the the Active and Standby instances, are properly enabled.

Start

  1. Log in to the Active instance. 
  2. Click the Diagnostics tab at the top of the WebUI.
  3. In the left navigation pane, go to High Availability > HA Status Details to view the HA status.


  4. Repeat steps 1 to 3 on the Standby instance.


Install an HA License

Install the HA license that applies to both devices.

Note

In step 3 of the following procedure, select SWe Edge from the Version dropdown list.

Attention

When you apply the HA license to the Active device, allow approximately 10 minutes for the license to appear and sync with the standby device.

Start

  1. Log in to the Active instance.
  2. Click the Settings tab at the top of the WebUI.
  3. In the left navigation window, go to System > Licensing > Install New License.
  4. Click Choose File and upload your license key.
  5. Click Decode to see the details of the license.
  6. Click Apply. 
  7. In the left navigation pane, select System > Licensing > Current Licenses. The Current Licenses pane opens on the right.
  8. In the Feature Licenses section, verify the license count that is currently available on the system is as required.
