Description (partial)

The following messages may appear at the beginning of the running configuration even when
everthing is normal :

"IP unicast distributed CEF switching has to be enabled on the physical interface"

The message is surely harmless but shouldn't be there anyway.

This problem is visible on a Cisco 7500 Series router when running Distributed CEF.
