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:.

#kstat ixge:0 grep mac_mtu

mac_mtu

8192

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:.

#ifconfig ixge138000 ixge138000: flags= 201000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4,CoS> mtu 8170 index 5

inet 192.12.38.69 netmask ffffff00 broadcast 192.12.38.255 ether 0:3:ba:c4:f7:1d
