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.
