Enabling High Availability an an SBC SWe Edge

The following workflow defines the procedures to deploy HA on an SBC SWe Edge.

Prerequisites 

Before you begin, make sure you have the following:

• Hardware Requirements
  • Two SBC SWe Edge instances ESXi host with
    • a minimum of 4 vCPUs
    • a minimum of 4 GB of RAM
    • a minimum of 3 to a maximum of 5 virtual network interface cards (NICs):  
      • 1 for the Management port,
      • 1 or 3 for Media/Packet ports

      • 1 for the HA port
        

        Note

        Regardless of whether you choose to use 3 or 5 virtual NICs, the last Media/Packet port is converted to an HA port. You cannot configure the HA port for signaling and media call handling, as it is used for such purposes as fault detections and storing and retrieving data from the database store.

        
        

    • all 5 network interfaces (mgt0, pkt0, pkt1, pkt2, pkt3) mapped through network configuration

• Software Requirement
  • HA supported version is installed on the system, for example, release 12.1.

• Ethernet Interface Requirements 

• • a dedicated HA port

  • Media (packet) ports

  • a Management port

    Interface Type	Limitations and Characteristics
    Dedicated HA port	Once you enable the HA feature on your SBC SWe Edge, you can only configure the static IP addresses on the Active and Standby instances of the HA port, which must be on the same subnet.
    Media (packet) ports	Only static IP address are supported in SBC SWe Edge release 12.1.
    Management port	You can use either static or DHCP IP addresses and configure different IP addresses on both the Active and the Standby instances.

Enabling High Availability on Active and Standby SWe Edge Instances 

Enable HA on the Active and Standby SWe Edge instances to increase the stability of the system during mid-call failovers.

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 in. The Remote IP is the other HA IP address of the other instance, as mentioned in the the Enabling High Availability an an SBC SWe Edge 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.
    
    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 right hand corner of the WebUI.
    
    The HA Role is Shown at the Right-hand Corner of the Instance WebUI
    

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

Verifying High Availability Status 

Verify the HA pair status to ensure that both the Active and the Standby SBC SWe Edge 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.
