ifconfig {device_name} plumb ifconfig {device_name} {ip_addr} netmask {netmask} up ifconfig -a

Easiest: dladm show-dev

Alternate: ndd -get /dev/{device_name} link_mode 0 = half-duplex 1 = full-duplex ndd -get /dev/{device_name} link_speed 0 = 10 Mbit 1 = 100 Mbit 1000 = 1 Gbit

List all properties, on some cards link_mode/speed does not exist. Look for adv_**_cap and query for value that is on (=1). ndd /dev/{device_name} \?

Link status ndd /dev/{device_name} link_status 0 = no 1 = yes

dladm create-aggr -d {dev} -d {dev} ... {key}
