Summary: Gigabit ethernet cards.

Hi Friends,
Thanks for the replies. Yes the default MTU for
Ethernet is 1500 but for gigabit ethernet we can have
jumbo frame MTU to the Maximum of 9000. I Guess with
standard SUN's standard issue gigabit cards as
suggested by Joe, But we have an Intraserver Cards and
I could successfully set the MTU to 9000. The
procedure is.

Create a file "/etc/jumbo.alt<num>" where alt is the
device name and num could be number of the device for
which you intend to configure. Edit the file and enter
the MTU size you set (9000 in this case). Then reboot
the system for configuration to take effect. You could
check this with "ifconfig -a".

Best Regards.
Rizwan Merchant.
