If a managed switch and all attached devices both support VLANs and Jumbo Frames, is it possible to mix VLANs with jumbo frames and VLANs with standard frames on the same switch port / ethernet card?
If it is possible, should I expect it to work in any environment or there are specific items (server ethernet card, ethernet card driver, server operating system, switch brand/model, etc.) that could cause problems in such a mixed environment?
After testing and using it for some months, I can say that yes it works.
The switch MTU settings acts merely as it names suggests, a maximum transfer unit [size]. Increasing it above what a VLAN hosts are actually using will not affect traffic in any way that I know of.
