greg2895 Posted September 12, 2017 Share Posted September 12, 2017 I recently bought 2 asus XG-C100C 10gbe nic's one for unRaid and one for the client. It supports jumbo frames 9kb which I was able to enable on the windows client machine. The problem is on the unRaid machine. When I run "ifconfig eth0 mtu 9000" to test it out I get "SIOCSIFMTU: Invalid argument". I am currently running 6.4.0-rc8q. Quote Link to comment
bonienl Posted September 12, 2017 Share Posted September 12, 2017 Why don't you use the GUI? It has the possibility to set the MTU size and changes made this way willl stick after a reboot. Quote Link to comment

I changed the mtu in the gui and rebooted however the dashboard still shows eth0 mtu as 1500 even though the gui setting is grayed out at 9000 now. Quote Link to comment

Your NIC doesn't support jumbo frames. Quote Link to comment
Mofarocker33 Posted April 27, 2023 Share Posted April 27, 2023 Funktioniert einwandfrei mit genau der Angegebenen Karte. Ich konnte auch den Wert nicht ändern und habe es dann in der passenden Config geändert: Unraid Wiki Artikel: https://wiki.unraid.net/Improving_unRAID_Performance#Jumbo_Frames -> /boot/config/network.cfg MTU=9000 1 Quote Link to comment
