Reporting the Link Partner Capabilities

Table 2-8 describes the read-only link partner capabilities.

Table 2-8 Read-Only Link Partner Capabilities

Parameter 

Values 

lp_autoneg_cap

0 = No auto-negotiation  

1 = Auto-negotiation 

lp_100fdx_cap

0 = No100 Mbit/sec full-duplex transmission 

1 = 100Mbit/sec full-duplex 

lp_100hdx_cap

0 = No 100 Mbit/sec half-duplex transmission 

1 = 100 Mbit/sec half-duplex 

lp_10fdx_cap

0 = No 10 Mbit/sec full-duplex transmission 

1 = 10 Mbit/sec full-duplex 

lp_10hdx_cap

0 = No 10 Mbit/sec half-duplex transmission 

1 = 10 Mbit/sec half-duplex 

If the link partner is not capable of auto-negotiation (when lp_autoneg_cap is 0) the information described in Table 2-8 is not relevant and the parameter value = 0.

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