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.
