Installation guide

Network Adapter Card Installation Guide - Book II

To start the VLAN interfaces, perform the following procedure:

1. Enter the commands:

ifconfig skge0 plumb <hostname> broadcast +

netmask + up

ifconfig skge100 plumb <hostname> mtu 9000

broadcast + netmask + up

2. Exchange <hostname> with the hostname you have chosen for the

VLAN.

3. Now enter 'ifconfig -a' again to check if all interfaces are set up

correctly.

4. Now you can try to ping to another machine to check whether or not

the connection works.

Additionally, you have the possibility to check the VLAN settings for a

specific interface by use of the 'ndd' command. If you want to know the

settings for skge100 from the example above, enter the command:

ndd /dev/skge100 vlan_props

If VLAN support is enabled on the according interface, you get a list of

four parameters (used in skge.conf):

— VLAN number: This is the number of the VLAN, for skge100 it

is 100.

— VLAN ID: This is the VLAN ID you have chosen.

— VLAN Port: Actual port used by the VLAN.

— VLAN Jumbo Frames: Did you choose jumbo frame support?

If VLAN support is disabled, you get the following message: "No VLAN

support on skgeX enabled." X is the number of the according interface.

For our example the output will look like the following:

VLAN number: 100

VLAN ID: 4

VLAN Port: A

VLAN Jumbo Frames: Yes

For more details about 'ndd' refer to Tuning on page 106.
