Defining the Number of Back-to-Back Packets to
Transmit
The
pace_size
parameter (see
TABLE B-6
) defines the maximum number of back-to-
back packets you can transmit at one time. If the value is zero, there is no limit to the
number of back-to-back packets that can be transmitted.
Reporting Transceiver Capabilities
TABLE B-7
describes the read-only transceiver capabilities. These parameters define
the capabilities of the hardware. The internal transceiver can support all of these
capabilities.
TABLE B-6
Back-to-back Packet Transmission Capability
Parameter Values Description
pace_size
1 to 255
0
= Number of back-to-back packets transmitted at one time
= No limit to the number of back-to-back packets that can be
transmitted (default)
