Posted by admin on August 21st, 2008 Maximum Transmission Unit
(MTU) the size (in bytes) of the largest packet or frame that a
given layer of a communications protocol can pass onwards. The
MTU may be fixed by standards (as is the case with Ethernet) or
decided at connect time. A higher MTU brings higher bandwidth
efficiency. However, large packets can block up a slow interface
for some time, increasing the lag for further packets. The MTU
for ethernet is 1500 bytes, 1492 for PPPoE and 576 for Dialup.
In very rare occasions, you may need to change the MTU size due
to connectivity issues with your ISPs or in a VPN environment on
your openSUSE. The following procedure should help to change the
Maximum Transmission Unit (MTU) in openSUSE. In Network Manager
If you are using Network-Manager to control the network settings
in your openSUSE then 1. From the menu, click Computer – YaST.
