- vManage alarms ہمیشہ پہلا قدم ہیں — CLI چھونے سے پہلے یہ صحیح layer کی طرف اشارہ کرتے ہیں۔vManage alarms hamesha pehla qadam hain — CLI chhune se pehle ye sahi layer ki taraf ishara karte hain.vManage alarms are always the first stop — they point you at the right layer before you touch the CLI.
- Stack کو اوپر سے نیچے troubleshoot کریں: control connections → OMP summary → IPsec tunnel state → application flow۔Stack ko oopar se neechay troubleshoot karen: control connections → OMP summary → IPsec tunnel state → application flow.Troubleshoot the stack top-down: control connections → OMP summary → IPsec tunnel state → application flow.
- WAN interface پر packet capture CLI کے دعوے کی تصدیق کرتا ہے: up ہونے پر ESP، down ہونے پر صرف control۔WAN interface par packet capture CLI ke daaway ki tasdeeq karta hai: up hone par ESP, down hone par sirf control.Packet capture on the WAN interface confirms what the CLI claims: ESP when up, control-only when down.
- Logs اور events تاریخ بتاتے ہیں — ہر log line کو alarm سے ملائیں تاکہ اصل troubleshooting مہارت بنے۔Logs aur events tareekh batate hain — har log line ko alarm se milayen taake asal troubleshooting maharat bane.Logs and events tell the history — match each log line to the alarm to build the real troubleshooting skill.
- REST API: authenticate کریں، session cookie لیں، پھر device/alarm data GET کریں — GUI کے بغیر automation۔REST API: authenticate karen, session cookie len, phir device/alarm data GET karen — GUI ke baghair automation.REST API: authenticate, get a session cookie, then GET device/alarm data — automation without the GUI.

❓ Tunnel down — troubleshooting ترتیب کیا ہے؟Tunnel down — troubleshooting tarteeb kya hai?Tunnel down — what is your troubleshooting order?
پہلے alarms، پھر control connections، پھر OMP routes، پھر data tunnel — اوپر سے نیچے: management → control → data۔Pehle alarms, phir control connections, phir OMP routes, phir data tunnel — oopar se neechay: management → control → data.Alarms first, then control connections, then OMP routes, then the data tunnel — top-down: management → control → data.
❓ WAN packet capture میں کیا نظر آنا چاہیے؟WAN packet capture mein kya nazar aana chahiye?What should a WAN packet capture show?
Tunnel up ہونے پر ESP packets نظر آتے ہیں؛ down ہونے پر صرف control ٹریفک۔ Capture کو CLI state سے ملائیں۔Tunnel up hone par ESP packets nazar aate hain; down hone par sirf control traffic. Capture ko CLI state se milayen.When the tunnel is up you see ESP packets; when down, only control traffic. Match the capture to the CLI state.
❓ SD-WAN REST APIs کیوں استعمال کریں گے؟SD-WAN REST APIs kyun istemal karenge?Why would you use the SD-WAN REST APIs?
ڈیوائس status، alarms اور statistics programmatically نکالنے کے لیے — dashboards، health checks، خودکار tickets — GUI کے بغیر۔Device status, alarms aur statistics programmatically nikalne ke liye — dashboards, health checks, khudkar tickets — GUI ke baghair.To pull device status, alarms and statistics programmatically — dashboards, health checks, automated tickets — without the GUI.
