I want to enable jumbo frames permanently.
Temporarily i am using:
sudo ifconfig eth0 mtu 8192
and everything is working fine,I have tested it.
But when i reboot,again the mtu size is reset to 1500.
I tried this to permanently set it :
sudo gedit /etc/network/interfaces
and added the last 6 lines:
iface lo inet loopback
iface eth0 inet static
then I restart networking like this:
sudo /etc/init.d/networking restart
and reboot my system.
But now I am unable to connect to my network,says "wired network device not managed"
How to correctly enable jumbo frames permanently?
P.s.: I am directly connecting a GigE camera to a GigE network adapter (Intel 82579LM),which is 1000 Base-T compatible.Using ubuntu 12.04 (64 bit)
