What is the maximum JumboFrame MTU size for a Zyxel XGS1930-28HP

eddeig

Hello,
May I kindly ask what the maximum Jumboframe MTU Size is for Zyxel XGS1930-28HP?

Must I enable Jumboframes (where would I find this setting in the GUI?) or is this enabled by default?

Many thanks for your help and kind regards,
Francisco

Hi @eddeig ,

The XGS1930-28HP support 9 K jumbo frame by default, you don't need to set anything on switch.

For more details about the XGS1930-28HP, please refer to the datasheet:

Hi Judy,

Many thanks for your answer. I'm a little confused. May I kindly ask you to have a look at this statement, I just found. It is also from Zyxel Support. It say's "at least 9K. you say "9K". I need to know if we can forward Max Frame Size : 9216 IP-MTU : 9198.
Can you conform that IP-MTU 9198 can be forwarded?

Many thanks for your help.

Kind regards,
Francisco

Hi @eddeig ,

We recommend following the information in the datasheet. So, ensure you connect the XGS1930-28HP to devices have jumbo frames set to below 9K for compatibility.

Hello Judy,

Many thanks for your answer. The problem is, that I can not change the MTU of the periphery, which is "baked inn" at MTU 9198 (video-cameras) :-(

Does Zyxel have switches that support a higher MTU size then 9k?

Kind regards,
Francisco
