[c-nsp] Safe to enable CEF on live 3725 production router?

[Rodney Dunn]

For the most part yes assuming you hit some random bug.

What does 'sh int stat' say for the interfaces?

If it's showing process switching that is a problem.
If it's route cache (fast switching) it's probably pretty unlikely
turning on CEF will fix it although it should still be done.
