I'm mot sure if CEF is working att all.
-----------------
We are running ios Version 12.0(4a)WX5(11) on the MSM.
CEF is enabled:
spt-3-4-ro#sh ip cef summary
IP CEF with switching (Table Version 19976)
628 routes, 0 reresolve, 0 unresolved (0 old, 0 new)
628 leaves, 99 nodes, 177132 bytes, 19981 inserts, 19353 invalidations
0 load sharing elements, 0 bytes, 0 references
2 CEF resets, 0 revisions of existing leaves
refcounts: 26756 leaf, 25600 node
Adjacency Table has 464 adjacencies
------------
But show interfaces stat does not show anything in the route cache counters, everything is only in the procesor counter. According the documentation for CEF "Execute the show interface stats command and confirm incrementing hits for route cache inbound.
Note: The route cache counter includes both fast-switched and CEF-switched packets."

Are ther some explanations for why the Route cache is 0 for all interfaces?
