DELL OS10 MTU Problem
We have trouble with some S4128F-ON-Switches running OS Version: 10.5.2.3.
We are runnning a NSX-environment with requires a MTU-size larger than 1600. So we configured MTU-size 9216 on the interfaces and the portchannels. We are not able to send packet larger than 1400 bytes without defragmentation. This will not work for ouur NSX environment....
Any Ideas?

Hola, no estoy familiarizado con NSX. Si ya ha comprobado el artículo en el post de Diego y establecer el tamaño de MTU en el interruptor. Creo que podría ser usted puede comprobar servidor final configurado tamaño de MTU. Sólo haciendo brainstroming, si el tamaño de MTU no está configurado mismo tamaño, que no será capaz de hablar entre sí correctamente. O el cable puede estar dañado o ser compatible con QSFP+ 4x(10GBASE-CR). O compruebe que la red tiene otros dispositivos que tienen un tamaño de MTU pequeño. Pueden causar alguna fragmentación.

Hello @cyrano6666
Please, check this article and let me know if you find it useful How to configure MTU (Maximum Transmission Unit) for Jumbo Frames on Dell Networking Force10 switches:

Also, make sure to check the firmware. I know for sure that older firmware revisions had a lower maximum mtu size. In the newer revisions it has being increased.
Regards.
