看驻波
一,需要开的参数,feature:
1,激活以下feature
VSWR
72Licensing=1,OptionalFeatures=1,VswrSupervision=1featureStateVswrSupervision1(ACTIVATED)
72Licensing=1,OptionalFeatures=1,VswrSupervision=1licenseStateVswrSupervision1(ENABLED)
72Licensing=1,OptionalFeatures=1,VswrSupervision=1serviceStateVswrSupervision1(OPERABLE)
2,设置参数:
vswrSupervisionActive设置为true,默认为false
vswrSupervisionSensitivity设置为100,意为门限1.5;默认为1,门限3
对于RRUL81,请将portA,B,C,D,E,F,G,H设置为true,请不要将portI设置为true
对于RRUL62,请将portA,B设置为true,请不要将portR设置为true
因为对于RRUL81,只有A到H才有VSWR监控的功能,I口是没有的
同样对于RRUL62,只有AB口有VSWR监控的功能,R口是没有的
3,参数含义
vswrSupervisionSensitivity =1{1..100}

Therelationbetweenthesensitivityandreturnlossonthe RU isdefinedas:

4,RRUL81如下来看
我们可以“lhrupsv”看“returnLoss”!
0002BXP_3_1:
ch3:
txpwr(-27.071273)torPwr(-27.793604)rxPwr(-42.022749)returnLoss(128) ---------128标示-12.8db,对应下表1.59之间
我们的门限是1.5,超过门限,所以看到报警如下:
RfPort=D,也就是上面的ch3(从ch0起始)

38MVswrOverThresholdAuxPlugInUnit=RRU-2,DeviceGroup=ru,RfPort=D(VSWRoverthreshold)
5,RRUL62通过如下命令来看
HGXX>lhruvswrrtls1-----------1标示RRUL上的B口,0标示A口
读出
=============================================================================================
$lhshBXP_2_1vswrrtls1
BXP_2_1:
vswrreturnloss:
BXP_2_1:
[ch1:

对应上表,这个90也超出范围,1.5
对应alarm

对于RRU侧(2通道和8通道都用一个命令)
lhrufpgar0xc8c
低16bit表示CPRI断过的次数(不会清零,除非RRU重起或者断电),比如DU重起,这个counter是会加1的
高16bit表示当前这次连接的BER, 每次CPRI断后会清零
对于DUL21侧
这些寄存器是读清零寄存器,也就是说,你可以先读一次(第一次读的值没有意思),这个时候寄存器会清零,等待1分钟后,再读这个寄存器,如果寄存器值非0表示有BER
lhsh000100rdmdio0x10 读第一个DU板的BER
lhsh000200rdmdio0x10 读第二个DU板的BER
lhsh000300rdmdio0x10 读第三个DU板的BER
对于DUL20侧
lhsh000100rdfpga 0x1C04 读DU板A口的BER
lhsh000100 rdfpga 0x1C24 读DU板B口的BER
lhsh000100 rdfpga 0x1C44 读DU板C口的BER
▪ 如何在moshell中读取DU和RRU光模块信息
1,附件是成都RRU研发给出的光路,光功率工作范围,详情见附件。

RDH10247/3Delta:
TXpower:

RXsensitive:

2,通过下面命令读取DU板上的光模块信息,20,21均适用。
以下信息均来自成都研发同事分享!

3,读取RRU侧光模块信息,RRUL62目前看是好用;RRUL81与研发同事说的不太一样,就不要用了。
