Layer 2 Configuration Checking
You can view the MTU configuration of a

Layer 3 Configuration Checking
You can do this by invoking the
ifconfig
command on a preconfigured interface as
shown in the above examples:.
# kstat ce:0 | grep link
link_T4 0
link_asmpause 0
link_duplex 2
link_pause 0
link_speed 1000
link_up 1
# kstat ce:0 | grep mac_mtu
ifconfig ce123000
ce123000: flags=1000843<.....> mtu 9194
