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.
Exclude Select this option to exclude the packets that match the specified criteria from this classifier.

field in the packets.
If you select Unchange , the EMG3425-Q10A keep the DSCP field in the packets.
802.1P Mark Select a priority level with which the EMG3425-Q10A replaces the IEEE 802.1p priority field
in the packets.
