Destination MAC Address
Destination MAC Mask:
The selected Code Point gives the
corresponding priority to the packets that
satisfies the rules set below.
A packet belongs to SET-1, if a binary-AND of
its source MAC address with the Source MAC
Mask is equal to the binary-AND of the Source
MAC Mask and this field.
This is the mask used to decide how many
bits are checked in Source MAC Address.
A packet belongs to SET-1 then the result
that the Destination MAC Address of its
header binary-AND to the Destination MAC
Mask must equal to the result that this field
binary-AND to the Destination MAC Mask.
This is the mask used to decide how many
bits are checked in Destination MAC Address.
