Sun Microsystems X1150A manual Flow Control Parameters, 2Operational Mode Parameters

TABLE 4-2Operational Mode Parameters (Continued)

Parameter	Description
adv-100hdx-cap	Local interface capability advertised by the hardware
	0	= Not 100 Mbit/sec half-duplex capable
	1	= 100 Mbit/sec half-duplex capable (default)
adv-10fdx-cap	Local interface capability advertised by the hardware
	0	= Not 10 Mbit/sec full-duplex capable
	1	= 10 Mbit/sec full-duplex capable (default)
adv-10hdx-cap	Local interface capability advertised by the hardware
	0	= Not 10 Mbit/sec half-duplex capable
	1	= 10 Mbit/sec half-duplex capable (default)

Note –If a parameter’s initial setting is 0, it cannot be changed. If you try to change it, it will revert back to 0.

If all these parameters are set to 1, autonegotiation will use the highest speed possible. If all these parameters are set to 0, you will receive the following error message:

NOTICE: Last setting will leave ce1 with no link capabilities.

WARNING: ce1: Restoring previous setting.

Flow Control Parameters

The ce device is capable of sourcing (transmitting) and terminating (receiving) pause frames conforming to the IEEE 802.3x Frame Based Link Level Flow Control Protocol. In response to received flow control frames, the ce device can slow down its transmit rate. On the other hand, the ce device is capable of sourcing flow control frames, requesting the link partner to slow down, provided that the link partner supports this feature. By default, the driver advertises both transmit and receive pause capability during autonegotiation.
