•
Destination MAC Wildcard Mask—Enter the mask to define a range of MAC
addresses. Note that this mask is different than in other uses, such as subnet mask. Here,
setting a bit as 1 indicates don't care and 0 indicates to mask that value.
Given a mask of 0000 0000 0000 0000 0000 0000 1111 1111 (which means that
NOTE
you match on the bits where there is 0 and don't match on the bits where there are 1's).
You need to translate the 1's to a decimal integer and you write 0 for each four zeros. In
this example since 1111 1111 = 255, the mask would be written: as 0.0.0.255.
•
