Title: Jumbo Frames / MTU size?
Post by: kvdv on December 01, 2008, 09:26:24 AM

Hi, 

I'd like to use Jumbo Frames but I cannot seem to find any official documentation about it.

Can somebody tell me the exact MTU size I can use with the DIR-855?

Thanks,
Kris

The switch can handle 9k frames, however this causes issues with the NAT and the UI becomes unresponsive.

So what max. MTU size is advised then, to keep all things stable and safe?

The MAX I recommend is 1500. The switch performs the best at this frame size. However if you insist on using jumbo frames 4k is acceptable.

How do I change the LAN MTU on the switch (not the WAN MTU)  ?

It's auto-sensing.
