You have non-XL DFC line cards...so the system falls back to the best
operating mode your worst card can do.

Good day all,
As we all know, the Sup720 has it's limitations with regards to it's ability to
handle large routing tables.
Looking today, I was surprised to see that two of my Sup720-3BXLs are showing
that I only have a MAX cef ability of 239K when all the docs I read show they
should be defaulting to 512K.
Did I get screwed on hacked together SUPs or do I have a line card effecting my
ability to scale my CEF table? IOS version limitation? Info pasted below.
Thanks for the insight as always.
