There are two ways to modify the MAC address of the NIC.

1. Use ifconfig:

# ifconfig ethX hw ether YY:YY:YY:YY:YY:YY

,where X is the device number assigned by Linux kernel, and

YY:YY:YY:YY:YY:YY is the MAC address assigned by the user.

2. Use ip:

# ip link set ethX address YY:YY:YY:YY:YY:YY

,where X is the device number assigned by Linux kernel, and

YY:YY:YY:YY:YY:YY is the MAC address assigned by the user.

Jumbo Frame:

Transmitting Jumbo Frames, whose packet size is bigger than 1500 bytes, please

change mtu by the following command.

# ifconfig ethX mtu MTU

, where X=0,1,2,..., and MTU is configured by user.
