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.

TABLE B-6Back-to-back Packet Transmission Capability

Parameter Values Description

pace_size 1 to 255 = Number of back-to-back packets transmitted at one time

0= No limit to the number of back-to-back packets that can be transmitted (default)

Reporting Transceiver Capabilities

TABLE B-7describes the read-only transceiver capabilities. These parameters define the capabilities of the hardware. The internal transceiver can support all of these capabilities.

TABLE B-7Read-Only Transceiver Capabilities

Parameter	Values	Description

autoneg_cap		Local transceiver capability of the hardware
	0	= Not capable of auto-negotiation
	1	= Auto negotiation capable
100fdx_cap		Local transceiver capability of the hardware; initialized at startup
	0	= Not 100Mbit/sec full-duplex capable
	1	= 100Mbit/sec full-duplex capable
100hdx_cap		Local transceiver capability of the hardware; initialized at startup
	0	= Not 100Mbit/sec half-duplex capable
	1	= 100Mbit/sec half-duplex capable
10fdx_cap		Local transceiver capability of the hardware; initialized at startup
	0	= Not 10Mbit/sec full-duplex capable
	1	= 10Mbit/sec full-duplex capable
10hdx_cap		Local transceiver capability of the hardware; initialized at startup
	0	= Not 10Mbit/sec half-duplex capable
	1	= 10Mbit/sec half-duplex capable
