Today we would like to share a case about the issue that the ONT configuration status fails on Huawei OLT. Please see more information shown below.
Product model: SmartAX MA5608T.
ISSUE DESCRIPTION
After an ONT is added to the MA5608T, a user runs the display ont info command to query the ONT status. The command output shows that the config state is failed.
F/S/P : 0/0/0
ONT-ID : 115
Control flag : active
Run state : online
Config state : failed
Match state : match
ISSUE ANALYSIS
1. Run the display ont failed-configuration command to check the ONT configuration restoration failure information.
MA5608T(diagnose)%%display ont failed-configuration 0/0/0 115
------------------------------------------------------------------------------
ONT ID : 115
The number of failed config: 3
------------------------------------------------------------------------------
Config item : ONU GEM mapping (gem mapping)
Config parameter : gem index(15), mapping(0)
Failed cause : Over ONU capability
------------------------------------------------------------------------------
Config item : ONU GEM port (gem add)
Config parameter : Gem Index(15)
Failed cause : Over ONU capability
------------------------------------------------------------------------------
Config item : ONU TCONT (tcont, ont tcont bind)
Config parameter : Tcont(11)
Failed cause : Over ONU capability
------------------------------------------------------------------------------
2. Query the ONT line configuration.
ont-lineprofile gpon profile-id 50 profile-name "diagnostics"
tcont 11 dba-profile-id 10
gem add 15 eth tcont 11
gem mapping 15 0 vlan 22
commit
quit
ont-srvprofile gpon profile-id 50 profile-name "diagnostics"
ont-port pots 1 eth 2
port vlan eth 2 translation 22 user-vlan 22
commit
service-port 124 vlan 22 gpon 0/0/0 ont 115 gemport 15 multi-service user-vlan 22
3. Confirm that the ONT supports a maximum of 8 T-CONTs.
OLT judgment logic: if the number of T-CONTs reported by the ONT is greater than or equal to the number of T-CONTs reported by the ONT, the OLT determines that the number exceeds the ONT capability set.
ROOT CAUSE
The number of configured T-CONTs exceeds the maximum capability of the ONT.
SOLUTION DESCRIPTION
Change the T-CONT range from 0 to 7 and bind the T-CONT to the ONT again. The configuration status is restored.
