RE: DSCP bit values in OEQ... really????

To convert DSCP AF values to decimal, multiply the first digit by 8, and
the second digit by 2, and add the two values:

AF21 - (2*8) + (1*2) = 18

AF31 - (3*8) + (1*2) = 26

The process can be reversed by dividing the decimal value by 8, and the
remainder by 2:

30 - 30/8 = 3, remainder of 6, 6/2 = 3 = AF33

CS codes can just be converted by multiplying by 8, CS3 = 24

Subject: DSCP bit values in OEQ... really????

Do I really need to memorize bit values for DSCP? (e.g. EF, AF11, etc.)
I was
working through a sim and came across a question asking for the 6 left
most
bits in the TOS field with a DSCP value of EF... If so, is there an
easy way
to memorize these?
