Beyond referring to port GUIDs, I'm also referring to items like:

sl: 0
mtu-limit: 1
rate-limit: 1
packet-life: 12
path-bits: 2,4,8-32

vlarb-high: 0:255,1:127,2:63,3:31,4:15,5:7,6:3,7:1
vlarb-low: 8:255,9:127,10:63,11:31,12:15,13:7,14:3
vl-high-limit: 10

sl2vl-table: 0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,7
sl2vl-table: 0,1,1,1,1,1,1,1,1,1,1,1,1,1,1,0

sl: 0
mtu-limit: 1
rate-limit: 1
packet-life: 12
path-bits: 2,4,8-32

This is really low level data, akin to the administrator manually 
programming the switch tables.  My take is that we should drop tons of 
this flexibility in favor of something much simpler for the administrator.
