Jumbo Frames lagg0

[VioletDragon]

Howdy folks,

I have some serious issues with Jumbo Frames in FreeNAS. I have enabled VLANS, Trunking and Jumbo frames on my HP Procurve switch. However when enabling mtu 9000 it causes the whole freenas server to dropout and slow issues when transferring too or from the Server.

I know its not a issue with my config on the switch because Linux to Linux works perfectly fine so does Windows to Linux or Linux to Windows with Full speeds. I am limited to 500mbs throughput in Linux however i get full speeds upto 1gbp throughput in Windows with 1500 MTU. I know the linux client isnt a issue here because i get 1gbp throughput from and too a linux box or from and too a Windows machine. Any ideas? because i am out of ideas.

Thanks.

Jack.

Depends upon the capabilities of the FreeBSD driver. What's the output of ifconfig?

Hey thanks for getting back to. The ouput is.

Ok, the driver is capable, from em(4):

Support for Jumbo Frames is provided via the interface MTU setting.
Selecting an MTU larger than 1500 bytes with the ifconfig(8) utility
configures the adapter to receive and transmit Jumbo Frames. The maximum
MTU size for Jumbo Frames is 16114.

Anything in /var/log/messages related to the network?

I should be able to get 9000 Jumbo with this card i do in linux anyway.

Sorry i forgot to attach the logs. Had to attach in a logs txt file as it exceeds 3000.
