Configuring DiffServ for HA Maintenance Traffic

You can configure Differentiated Services (DiffServ) for HA Maintenance traffic which flows between the active and redundant devices on the HA Maintenance network interface. The default DiffServ value for this traffic is 46, which should be sufficient in most setups. However, you may need to increase the DiffServ priority if you are also running non-HA traffic on this network. Prioritizing HA Maintenance traffic ensures low latency for this critical network traffic.

To configure DiffServ for HA Maintenance traffic:
1. Upload an ini file with the [HAMaintenanceIFDiffServValue] parameter configured to the required DiffServ value - 0 is the lowest priority (best effort) and 63 is the highest priority.
2. Restart the device with a save-to-flash for your settings to take effect.
