No DFCs on the platform to reply to YOUR questions Phil .
I think the CEF engine is located on the supervisor engine PFC3 .
"Show ip cef" shows cef is not running on the platform , so no Cef = no
wire-rate switching right ? I think the problem might come from this .
sclisgh022#sh ip cef
%CEF not running

Re: [c-nsp] 6704-10GE bug ? [NC]
Running out of space on the 3BXL would be impressive at this point,
unless you are doing testing... Also, when the TCAM fills up it will
give a message like "CEF table full, some prefixes will be software
switched", and starts dropping short-length prefixes from the TCAM.
I've seen that message with OSMs when they run out of memory for the
FIB, then it defaults to packets being switched by the PFC instead of
using distributed switching. Are you using DFCs on the 6704s?
