Configuration Checking
The jumbo frame configuration checking occurs at Layer 2 or Layer 3, depending on
the configuration method.
Layer 2 Configuration Checking
You can view the MTU configuration of a ixge instance at any time using the kstat
command. The kstat mac_mtu variable represents the complete size of the
Ethernet frame, which includes the Ethernet header, maximum payload, and crc .
This value is consistent with the definition of MTU presented by switch vendors.
Use the following command to get the information:.
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=
