 ### How to change speed of ASFVOLT16 NNI interface?
 
-Auto-negotiation on the NNI (uplink) interfaces is not tested. By default, the OpenOLT agent sets the speed of the NNI interfaces to 100G. To downgrade the network interface speed to 40G, add the following lines at the end of the qax.soc (/broadcom/qax.soc) configuration file. A restart of the bal_core_dist and openolt executables is required after the change.
