Currently, our NGAF Sangfor are showing something unusal

On one of the interface, showed the status "DNS not detected yet" on link state detection, shown on capture below
the link state detection method, are only using PING method, and not DNS lookup as shwon on capture below

we try to disable enable the link state detection and still the issue occured

Is there any way this status are shown and how to fix it

Thankyou

This behavior is expected and is mainly a UI/status display issue rather than a functional fault. Even though your Link State Detection is configured to use PING only the interface status summary still shows "DNS not detected yet" because the system displays all supported detection mechanisms (ARP / DNS / Ping) in the status line regardless of which ones are enabled. Since DNS lookup is unchecked no DNS probe is actually performed but the UI keeps the DNS field in an "idle / not detected yet" state instead of hiding it or marking it as N/A.

This does not affect link detection, failover or traffic forwarding as long as PING status is Normal (green check). Disabling and re-enabling Link State Detection will not change this label. There is no separate fix other than enabling DNS lookup and configuring a valid DNS test domain or upgrading firmware if a newer version improves the UI logic. Functionally your interface is healthy and no corrective action is required.
