中兴8905查看端口光功率命令
8905下的OLT有时好有时坏，有可能是光功率问题，之后打中兴客服询问得知8905不支持查看光衰，只能看得到端口的收发光功率，担心忘记，做一下记录：
首先进入要查看端口：
MAN.8905(config)#interface gei_2/11
MAN.8905(config-gei_2/11)#
MAN.8905(config-gei_2/11)#optical-inform monitor enable
MAN.8905(config-gei_2/11)#show optical-inform brief
If device is externally calibrated, only calibrated values are printed.
-Inf: not applicable, Tx: transmit, Rx: receive.
Optical Optical
Interface Temperature Voltage Current Tx Power Rx Power (Tx表示发出的，Rx表示收到的)
