To Check Layer 2 Configuration

View the maximum transmission unit (MTU) configuration of a ipge instance at
any time by 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.

To Check Layer 3 Configuration

Check the Layer 3 configuration, by invoking the ifconfig command on a
preconfigured interface as shown in the following example.

# kstat ipge:0 | grep mac_mtu

ifconfig ipge123000

ce123000: flags=1000843<.....> mtu 8192
