Get the Parameters value from 15000 + Huawei Router

1

Hi Guys,
How can we get the values of the parameters from a huge number of routers?
For example: if I have to get all WAN profile values, how could it get it,
one option is to write the parameters and get the result
if I have 20000 devices or routers how could I get the value of each.
