[SunHELP] boot net

[Bob Ruddy]

I have two qfe cards in a box. I am trying to setup the alias for "net" 
show-nets at the ok prompt shows me
a) /sbus at 54,0/SUNW,qfe at 1,8c30000
b) /sbus at 54,0/SUNW,qfe at 1,8c20000
c) /sbus at 54,0/SUNW,qfe at 1,8c10000
d) /sbus at 54,0/SUNW,qfe at 1,8c00000
e) /sbus at 50,0/SUNW,qfe at 1,8c30000
f) /sbus at 50,0/SUNW,qfe at 1,8c20000
g) /sbus at 50,0/SUNW,qfe at 1,8c10000
h) /sbus at 50,0/SUNW,qfe at 1,8c00000

Without trying each one of these how do I know which one would line up to 
qfe2 when the system is booted? Thanks.

Bob
