H3C交换机查看光功率、收发光情况的命令/方法
处理H3C的交换机光路时,特别麻烦,因为手头也没光功率测量计,所以把光模块接入后,如果undo shut后,还不懂,就比较难搞了。现在在网上找到可以查看光功率的命令,分享下:
- [H3C]_hidecmd
- Now you enter a hidden command view for developer's testing, some commands may
- affect operation by wrong use, please carefully use it with our engineer's
- direction.
- [H3C-hidecmd]_display transceiver ?
- diagnosis Diagnostic information
- interface Display by interface
- register Register information
- [H3C-hidecmd]_display transceiver diagnosis interface GigabitEthernet 1/0/25
- GigabitEthernet1/0/25 transceiver diagnostic information:
- Current diagnostic parameters:
- Temp(°C) Voltage(V) Bias(mA) RX power(dBm) TX power(dBm)
- 54 3.41 17.65 -7.45 -5.85
- Alarm thresholds:
- Temp(°C) Voltage(V) Bias(mA) RX power(dBm) TX power(dBm)
- High 85 3.70 65.00 0.97 0.97
- Low -10 2.90 10.00 -40.00 -13.01
- Parameters when first used on 2000.4.26:
- Temp(°C) Voltage(V) Bias(mA) RX power(dBm) TX power(dBm)
- 39 3.41 16.35 -7.21 -5.85
- Total account of alarms: 15

- 2014.04.09 RX power low
以下是端口没有插上模块的:
- [H3C-hidecmd]display transceiver diagnosis interface GigabitEthernet 1/0/27
- Error: The transceiver is absent.
- [H3C-hidecmd]display transceiver diagnosis interface GigabitEthernet 1/0/28
- Error: The transceiver is absent.
