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.
