Configuring Gigabit Ethernet Parameters

Using the lanadmin Tool with Gigabit Ethernet

Option

Setting

 

 

recv_coal_ticks*

Sets receive interrupt coalescing ticks [0 – 10000000]

 

 

stats clear

Clears all driver and adapter statistics

 

 

* These options require the desired value to be specified after the option name.

Examples

Speed To set the speed to 100 Mbps full-duplex on 1000Base-T, execute:

$ lanadmin -X 100fd nmid/ppa

NOTE

The lanadmin -Soption to set the speed is not supported on Gigabit Ethernet.

Stats Clear To clear all driver and card statistics, execute:

$ lanadmin -X stats clear nmid/ppa

Buffer Coalescing Threshold To set the send buffer coalescing threshold, execute:

$ lanadmin -X send_max_bufs 32 nmid/ppa

Note that the tuning option send_max_bufs requires the additional option 32 (the coalescing threshold).

Interrupt Coalescing Ticks To set the send interrupt coalescing ticks, execute:

$ lanadmin -X send_coal_ticks 2000 nmid/ppa

Note that the tuning option send_coal_ticks requires the additional option 2000 (the number of coalescing ticks).
