Re: OT: CEF debugging question

One of the main reason for traffic been punted to CPU is the failure of
hardware forwarding. It could be either there are feature that are not yet
supported in hardware ( ex some wccp / PBR variations,) or out of the scale
of the supervisor ( Netflow TCAM, NAT ). If it is production box i would say
go and open a tac case. If it is non production , use RP inband span as
pointed here in a earlier response or netdr to find out what gets punted.It
would help to post a sh run without the sensitive info, sh mod and sh proc
cpu sort.
