if ever na disable ung LAN port mo remotely through OLT OMCI or TR069 at na confirmed mo na hindi hardware defect, since meron ka access sa telnet, try mo if nagana ung override, run mo ung following commans sa telnet shell
Code:
ifconfig eth0 up
ifconfig eth1 up
ifconfig eth2 up
ifconfig eth3 up
eth0 = lan 1, eth1 = lan 2 and etc..
hindi naman sa hindi alam, aware naman ang iba sa GPON OMCI, TR069, SNMP and etc used for ISP provisioning, sa akin lng is irule out natin ung hardware defect before concluding to that kasi meron scenarios ung mga 2nd hand ONT na pull out from subs kasi may issue like
broken wifi antenna, putol2 ang signal, ports or iba pang issue.
if ever ma deploy naman ni converge ang provisioning sa OLT, it can still be bypassed and ignored sa ONT/CPE side either way, depende sa firmware.
