Chapter 28 - Maximum Transmission Unit (MTU)

Possible Hardware Problem

278

Mediatrix 1204

•

Value Type: REG_DWORD Number

•

Valid Range: 68 - the MTU of the underlying network

•

Default: 0xFFFFFFFF

•

Description: This parameter overrides the default MTU for a network interface. The
MTU is the maximum packet size in bytes that the transport will transmit over the
underlying network. The size includes the transport header. Note that an IP datagram
may span multiple packets. Values larger than the default for the underlying network
will result in the transport using the network default MTU. Values smaller than 68 will
result in the transport using an MTU of 68.

3.

To validate that the changes are correct, try to ping the Mediatrix 1204 with large packets once
restarted:

ping -l 2000

This will cause IP fragmentation, the first fragment being as large as the interface allows it. With the
MTU reduced, you should now receive an answer. For more informations, see:
