某局点S12508CR R8064版本,客户对一些端口做了一分四,目前都是只有1通道在使用,但是会持续出现2、3、4通道的告警,如下:
%Oct 9 09:10:18:379 2026 OPTMOD/4/OPTICAL_WARNING_OCCUR: -Slot=5; Transceiver warning alarm occurred. (PhysicalIndex=2282, PhysicalName=Ten-GigabitEthernet5/0/31:1, RelativeResource=(transceivertype:40G_BASE_CSR4_QSFP_PLUS,interface:XGE5/0/31:1,channel:4), ErrorCode=600029, Reason=The transceiver bias current change exceeded the threshold: Current change value = 5.83 mA, Change threshold = 3.50 mA.)

除以上电流变化的告警以外,还有收光过低等告警,都是在未使用的2、3、4通道上。
对于拆分口,光模块ras检查会按模块而不按channel检查,非本口使用的channel也会告警。内部已有问题单跟踪优化。
该打印不影响功能,如果四个通道都正常使用也不会有告警。
告警不影响设备使用,若不想见到持续告警,建议使用以下命令关闭打印:
hardware-alarm syslog resource-type transceiver disable
hardware-alarm trap resource-type transceiver disable
后续预计12月发布的年度版本会解决这个问题。
