This read-write object sets the queue limit, in bytes, for traced Frame Relay data awaiting transmission to the trace receiver; once exceeded, additional traced frames are discarded rather than queued. Unlike the receiver name and duration, this can be adjusted while a trace is actively running, letting an admin tune buffering on the fly if frames are being dropped due to a slow receiver link. Raising mscFrUniTraceQueueLimit from the default of 20 to 80 would give a trace session more buffer headroom before it starts discarding captured frames during a burst.
