Chapter 17: Radio Configuration (CLI)
Configuring Frame Cut-Through (CLI)
Using the Frame Cut-Through feature, frames assigned to queues with 4th priority pre-empt frames already in
transmission over the radio from other queues. After the 4th queue frames have been transmitted, transmission of
the pre-empted frames resumes.
Note
The Frame Cut-Through configuration must be identical on both sides of the link.

a CoS that is not assigned to the fourth priority queue.
