iTest TCL STC API modify read only streamblock attribute

Hi there,

I am trying to modify the MbpsLoad parameter from a streamblock using TCL STC API but it is coming back with the error "couldn't set the read only attribute":

TestCenter>eval stc::config streamblock5 -MbpsLoad 5

Failed to evaluate tcl command 'stc::config streamblock5 -MbpsLoad 5'

TestCenterException

StdOut =

StdErr =

Result = RuntimeError in config: couldn't set the read only attribute -MbpsLoad

Does anybody know how to modify this parameter? or is there a way to change the attribute "read only" to allow changes?

Thank you!!!

As MbpsLoad is the readonly attribute, we can not modify the value of it.

Where as we can modify the loadunit to MEGABITS_PER_SECOND. For this, we need to get the streamblockloadprofile1 to modify it.

The API commands to modify the loadunit to Mbps is: eval stc::config streamblockloadprofile1 -loadunit MEGABITS_PER_SECOND -load 50

Attached is the screenshot for your reference.
