Title: Why the fiber port can't be up? [Print this page] Author: GTAC-Daisy Time: 2020-7-23 17:19 Title: Why the fiber port can't be up? (1) check the optic cable, the optical fiber has two terminals：TX and Rx which need to corresponding to the module's TX and RX
(2) try to force speed 1000 and duplex full on both sides
Ruijie(config)#interface gi 0/24
Ruijie(config-if)#speed 1000
Ruijie(config-if)#duplex full
(3) If used third brand fiber module, try to change with Ruijie fiber module.
