To Discover Link Settings

kstat

command to discover link settings.

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

ce

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 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
