Layer 3 Configuration Checking
You can check the Layer 3 configuration by invoking the ifconfig command on a
preconfigured interface as shown in the previous examples:.
# kstat ixge:1 | grep link
link_asmpause 0
link_duplex 2
link_pause 0
link_speed 10000
link_T4 0
link_up 1
# kstat ixge:0 | grep mac_mtu
mac_mtu 8192
# ifconfig ixge138000
ixge138000: flags=
