▼To Show the Driver Statistics in a Solaris Environment

1. Use the kstat command to display driver statistics, for example:

#kstat nxge:1 grep rdc_packets

rdc_packets798982054

rdc_packets792546171

rdc_packets803941759

rdc_packets805674872

rdc_packets798714912

rdc_packets799293256

rdc_packets806470537

rdc_packets805413540

The previous example displays the receive packet counts on all of the eight Receive DMA channels on interface 1. Using the kstat nxge:1 shows all the statistics that the driver supports for that interface.

2.Use the kstat command to display driver statistics of a VLAN interface, for example:.

# kstat
