[AusNOG] Omg

[Matthew Moyle-Croft]

The issue was purely a long standing default TCAM carve up not an actual
hardware limitation.

See:
http://www.cisco.com/c/en/us/support/docs/switches/catalyst-6500-series-switches/116132-problem-catalyst6500-00.html

Note the date on the doc was >18 months ago.  Sup720s aren't exactly brand
new things.
