Configuring the maximum transmission unit

Configuring the maximum transmission unit

To configure the maximum transmission unit (MTU) for each link, perform one of these actions:

The default MTU value is 296. Increasing this value may increase throughput as packets can contain more data. However, it may also decrease throughput if packets are routed through systems with lower MTU values, as each packet is split (fragmented) into smaller packets for transmittal. You can experiment with this value to obtain the most desirable results.


NOTE: The suggested value for the MTU is 40 plus some power of 2. For example, the default value, 296, is 40 plus 2^8. Other possible values include 552, 1064, and 2088.
