DHCP

At the Enter MTU prompt, enter the MTU for your net-
work. You may need to contact your network administra-
tor for this information. The MTU is the size of the
largest datagram that your network can transmit. A value
of 1500 (the built-in default) is typical for most net-
works. Smaller values should only be used with the guid-
ance of your network administrator. 

NOTE:

The MTU must be between 576 and 1500, inclu-

sive.The MTU entry is optional.  If you do not enter a value
and press <Enter>, the factory default of 1500 is left
unchanged.

After you have entered the information, you are prompt-
ed with a 

Save Changes

screen. Select Yes or No as

appropriate. If you select Yes, you are given a confirma-
tion screen stating "

Changes saved.

"

Selecting No at the 

Save Changes

screen or selecting Ok

at the 

Changes saved

screen returns you to the Main

Menu.

When you exit the Main Menu via Exit or pressing the
Esc, the COMET will reset/reboot. The changes you
entered will take effect on the reset.
