Reporting the Link Partner Capabilities

TABLE B-8describes the read-only link partner capabilities.

TABLE B-8Read-Only Link Partner Capabilities

Parameter	Values	Description

lp_autoneg_cap	0	= No auto-negotiation
	1	= Auto-negotiation
lp_100fdx_cap	0	= No100Mbit/sec full-duplex transmission
	1	= 100Mbit/sec full-duplex
lp_100hdx_cap	0	= No 100Mbit/sec half-duplex transmission
	1	= 100Mbit/sec half-duplex
lp_10fdx_cap	0	= No 10Mbit/sec full-duplex transmission
	1	= 10Mbit/sec full-duplex
lp_10hdx_cap	0	= No 10Mbit/sec half-duplex transmission
	1	= 10Mbit/sec half-duplex

If the link partner is not capable of auto-negotiation (when lp_autoneg_cap is 0) the information described in TABLE B-8is not relevant and the parameter value = 0.

If the link partner is capable of auto-negotiation (when lp_autoneg_cap is 1) then the speed and mode information is displayed when you use auto-negotiation and get the link partner capabilities.
