The following taken out of a book says:
"The following access list uses a binary mask to match the precendece
levels 0, 1 and 2 only"
access-list rate-limit 25 mask 07
This is used with:
rate-limit input access-group rate-limit 25 conform-action set
prec-transmit 4
To me, that mask would match levels 0, 1, 2, 3, 4, 5, 6, 7
To make a mask for precedence levels 0, 1, 2, i would do:
000 prec 0
001 prec 1
010 prec 2
100 mask = 4, which would also match precedence 3. I see no way to
match 0, 1, 2 without also matching 3. Mask is opposite transposition as
a wildcard set.
If someone could offer some clarity, I would appreciate it.
