Description (partial)

 On a Catalyst 6000 series router, configured for WCCP redirection, packets may
 be software switched leading to elevated CPU usage.
 If a WCCP redirect ACL contains a permit entry for a protocol that does not
 match the associated WCCP service group the system reports the configuration
 error via a %WCCP-3-BADACE error message. However if the mis-matched protocol
 is UDP or TCP (UDP with a TCP-based service group or TCP with a UDP-based
 service group), no error message is generated and the hardware will punt
 packets to the RP for processing.
