Hi,
I'm looking at a ICND 2 question that shows 4 switches. Their Bids/MAC addresses are shown as:
0013.8039.9500
0013.80d7.d580
0013.8030.5e80
0113.80c7.9700
Looking at the answer I can tell that 0013.8030.5e80 is the root switch. But I don't understand why this is lower than 0013.80d7.d580 or 0113.80c7.9700.
Can you help?

hexadecimal works this way.
decimal = hexadecimal
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
comparing 0013.8030.5e80 from 0013.80d7.d580, 3 is lower than d(13)
comparing 0013.8030.5e80 from 0113.80c7.9700, 0 is lower than 1
thus making 0013.8030.5e80 the root switch
