$ rule: never mix CLIs_

Domain rule: OLT, S-Series and Zeus OS are different operational environments. Always use the documentation for the exact equipment and firmware.

GPON: An ONU can be online and still have no service. DBA/VLAN/LINE/RULE profiles, mapping/GEMPORT/flow and the end-to-end VLAN path must be analyzed together.

03 · PLAYBOOKS

Diagnosis by symptom

OLT G08/G16

ONU/ONT offline

Confirm PON, serial/ONU-ID and incident time.
Check ONU/PON state and alarms.
Validate optical power and ODN.
Compare ONUs behind the same splitter.
Validate authorization/profiles.
Raise the fault domain to PON/OLT if several ONUs are affected.

GPON

ONU online without service

Confirm PON/ONU stability.
Review DBA/VLAN/LINE/RULE profiles.
Validate mapping mode and GEMPORT.
Validate flow and VLAN.
Check OLT uplink/bridge.
Compare with an equivalent working CPE.

OLT

Entire PON unavailable

Check PON/laser/alarms.
Compare other PONs.
Check power and uplinks.
Inspect primary ODN.
Collect evidence before reboot.
Escalate if the scope reaches the entire OLT.

S2300G/S3300G

VLAN without traffic

Review running configuration.
Validate VLAN and port mode.
Check link aggregation when used.
Check STP.
Check MAC/ARP when applicable.
Compare with a working port.

S-Series

Loop / broadcast storm

Check CPU.
Check buffered logs.
Check storm control.
Check STP and topology.
Check aggregations.
Isolate the smallest possible segment.

S-Series

Degraded LAG

Check link aggregation.
Check physical interfaces.
Compare VLANs/MTU on both ends.
Check LACP and inconsistent members.
Validate traffic after correction.

Zeus OS

Wi-Fi client cannot connect

Check SSID/security.
Check client association.
Check VLAN and DHCP.
Check captive portal/RADIUS.
Check channel/country.
Correlate with Zeus INC Cloud when used.

Zeus OS

Slow/unstable Wi-Fi

Check signal and client count.
Check channel/width/interference.
Check Ethernet uplink.
Check firmware.
Check roaming/capacity.
Compare nearby APs.
