How can you tell what the lowest MAC address is in regards to STP? Is it the last two digits?
Ex: 00:1b:0d:db:5d:00 and 00:14:a8:a8:6c:40
Would the first MAC address be the lowest becuase the last two digits are 00?
Thanks

Start on the left, work towards the right.
00 = tie 1b is greater than 14, therefore the second MAC is lower.....
When comparing numbers, you'd want to compare the higher-order bits first (i.e.: left to right), as was suggested by the other respondent.

Nothing wrong with above, here is my effort.
Treat as a 12 digit hexadecimal number.
digits are -> 0123456789abcdef
Remove colons and read in the same way as you read any other multi-digit number except that you have 16 different digit values instead of 10.
00:1b:0d:db:5d:00 and 00:14:a8:a8:6c:40Considering 4th digit from left since first 3 are the same. b > 4 so top one is bigger and has *lower* STP priority.
b(hex) =3D 11(decimal)
