Events not appearing in real time
Symptom: customer drops and reconnects don't update on their own in Cpehub — they only show up when you sync manually.
What's happening
Cpehub updates CPE status in real time by receiving SNMP traps from the OLTs. If the traps aren't arriving, the dashboard "freezes": statuses stay outdated until a manual sync.
Step by step
-
On the affected OLT (in OLTs), confirm whether the TRAP badge is red.
-
Check the SNMP Trap configuration on the OLT itself — it needs to point to Cpehub. The per-manufacturer tutorials are at:
-
Check the network path: traps leave the OLT toward Cpehub over the VPN. A firewall or wrong route blocks the trap.
-
Track the traps arriving in Administration → SNMP Traps (received trap logs).
Most common causes
| Cause | Indication | Action |
|---|---|---|
| Trap not configured on the OLT | Red TRAP badge | Configure SNMP Trap (manufacturer tutorial) |
| Wrong trap destination | OLT sends to the wrong IP | Fix the destination on the OLT |
| Firewall blocking | SSH/SNMP OK, but no traps | Open the trap traffic |
| Unstable VPN | Intermittent traps | Stabilize the VPN |
When to escalate
- Trap correctly configured and still not arriving → network team (firewall/route) and, if needed, Cpehub support.
