Uncertified third-party transceivers or incompatible models will not disable ports directly, but will generate system fault alarms.
Taking Ciena 3930 switch as an example, we demonstrate procedures to query officially supported transceiver specifications.
Insert original Ciena 160-9103-900 transceiver into Ciena 3930 switch, View module operating status. The Oper State displays UCTF, which means Uncertified.
Figure 1 Ciena 160-9103-900 Transceiver
This is genuine Ciena factory module, so the alarm is not caused by non-original accessories.
Run command:
port xcvr show supported
It shows all officially matched transceiver models and corresponding rates under current system version.
The result proves 160-9103-900 is not included in supported list, resulting in uncertified alarm.
Referring to official supported list, install Moduletek SFP+ LR (compatible with Ciena XCVR-S10V31). Oper State turns to Ena (Enable), indicating successful module authentication.
Moduletek supplies high-quality compatible transceivers for Ciena switches. Welcome to inquire and purchase.
