▼To Check Layer 3 Configuration

●Check the Layer 3 configuration by using the dladm command with the show- link option, as shown in the following example:

	# dladm show-link
	e1000g0	type: non-vlan	mtu: 1500	device: e1000g0
	e1000g1	type: non-vlan	mtu: 1500	device: e1000g1
	e1000g2	type: non-vlan	mtu: 1500	device: e1000g2
	e1000g3	type: non-vlan	mtu: 1500	device: e1000g3
	nxge0	type: non-vlan	mtu: 9194	device: nxge0
	nxge1	type: non-vlan	mtu: 9194	device: nxge1
	nxge38001	type: vlan 38	mtu: 9194	device: nxge1

Enabling Jumbo Frames in a Linux

Environment

This section describes how to enable jumbo frames in a Linux environment.

▼To Enable Jumbo Frames in a Linux Environment

1.Ensure that the nxge software is installed.

#modprobe nxge

2.Plumb the Sun x8 Express Dual 10 Gigabit Ethernet Fiber XFP Low Profile Adapter interface:

#ifconfig eth2 xxx.xxx.xx.xxx up

where xxx.xxx.xx.xxx is the IP address of the interface.

3.Set the MTU for maximum performance:

#ifconfig ethx mtu 9194

Where x is the instance number of the interface you want to configure jumbo frames on.
