STP Priority: Lowest Mac-address

Hey guys,

So I'm over here look at STP and using the boson sim at work on the laptop and I'm curious would it be helpful on the exam to write out the 15 character hex chart?

IE:

1 = 1
2 = 2
3 = 3
4 = 4
5 = 5
6 = 6
7 = 7
8 = 8
9 = 9
10 = A
11 = B
12 = C
13 = D
14 = E
15 = F

example:

e.g 1 sw has 01-23-45-67-89-ab & another FF-BB-CC-AA-DD



to me 01-23-45-67-89-ab is the lowest cause F equals 15 and '0' equals well zero! icon_wink.gif

Obviously this would only an issue if STP priority is on two switches and they both have a priority of 0 or otherwise match with a priority below 65535 and then the lowest mac address is chosen, but I guess reading a mac address upon itself it good to find the root address. Outside of an exam I'm just use the 'Spanning-tree vlan [number] root primary' but this is a Cisco exam prep and I bet they will quiz me on everything!!!!!
