Source

MAC 

Address

Select the check box and enter the source MAC address of the packet.

MAC Mask

Type the mask for the specified MAC address to determine which bits a packet’s MAC 
address should match. 

Enter “f” for each bit of the specified source MAC address that the traffic’s MAC address 
should match. Enter “0“ for the bit(s) of the matched traffic’s MAC address, which can be of 
any hexadecimal character(s). For example, if you set the MAC address to 
00:13:49:00:00:00 and the mask to ff:ff:ff:00:00:00, a packet with a MAC address of 
00:13:49:12:34:56 matches this criteria.
