You may be able to reduce FGCP HA failover times by changing the the NP7 link scan interval. The NP7 link scan interval is the amount of time that a FortiGate with NP7 processors waits between scans to determine if a link has failed. A shorter NP7 link scan interval can cause the FortiGate to send gratuitous ARP packets sooner after an HA failover has occurred. config system npu set np-linkscan-interval endThe np-link-scan-interval range is 50 to 1000ms. The default NP7 link scan interval is 1000 milliseconds (ms). If your FGCPHA cluster experiences longer than expected HA failover delays (for example a 2-second interval for a failover to occur)reducing the NP7 link scan interval may reduce HA failover delays.
