Using Direct meter

[Hoangttrieu]

Hello,
I found a tutorial for using meter in https://github.com/haoyuz/p4-tutorials/blob/master/examples/meter/.
In this tutorial, they use "meter_array_set_rates" to set the data rate for the flow. Now, I want to set the data rates by using p4runtime. Do P4runtime-shell supports to do this? Thanks you very much

Yes.
For an indirect meter, try:

P4Runtime sh >>> me = meter_entry["<name of meter object>"]

P4Runtime sh >>> me?

You should be getting a help message about how to set rates.

Hello,
I did me.cir = to set the value. But I have another question about the unit. Do the rates in the P4runtime is units/microseconds?
Thanks in advance.
