hi guys for a special application, I need jumbo frames enabled in the network card. I have just checked, and C3600 only allows 1500 MTU. cat /sys/class/net/eth0/mtu 1500 I need 2000 MTU, 4000 MTU, 7000 MTU, or 9000 MTU can someone check the max MTU capability of the built-in lan on a C8000? ip link set eth0 mtu 1500 if you have "iproute2" installed, the above is an alternative command to set the MTU, but it only works if the hardware does support it. thanks =)
