how to use "subscribe" operation in openwsman?

Hi,
I am new here .

After I installed openwsman client(wsmancli) and the DASHRI(like a openwsman service)
I can use openwsman command line to enumerate the resoure.
for example: ./wsman enumerate http://http://schemas.dri.org/wbem/wscim/1/cim-schema/2/DRI_ComputerSystem

It is ok.The server feedback the right content as I wish.
So I think the connection between client and Server is ok.
The problem is that When I use the wsmancli to subscribe ,It cause errors.
The commond I used is like this:

./wsman--port 623 -u admin -p admin
--filter='SELEC * FROM CIM_AlertIndication'
--dialect="http://schemas.microsoft.com/wbem/wsman/1/WQL"
--notification-uri="http://localhost:8080/wsman"
--delivery-mode=pushwithack--subscription-expiry-time=60
subscribe http://schemas.dmtf.org/wbem/wscim/1/cim-schema/2/CIM_AlertIndication

the error is that :segmentation fault

I dont kown what is it mean.

And then I try to use wsmancli to "get" the value of resource,
some problems are happen such as:connection failed ,response code=400,
and I find the reason is that :Destination Unreachable.
I guess the problem is that I type the wrong command.

Is anybody kown the exactly command of openwsman(including subscribe and get/put……)?
Is anybody kown what is the problem of my test?

thanks very much

Regards !
