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

[Nassess, George]

Troubleshooting a strange problem, can ping customer's managed router
ATM WAN interface, with no loss. When pinging across the router to its
ethernet interface, we see occasional packet loss and delay. Not enough
to affect data, but enough to affect voice quality of H323 trunks that
delivers calls to their remote call center. I noticed their 3725 WAN
router does not have CEF enabled. We are feeling the pressure, and I
wanted to enable CEF as a troubleshooting step, but am not sure of the
impact on traffic in a live production router. Is it safe to do this
mid-day?
