Command History
Usage Guidelines You might want to collect statistics to better understand CEF patterns in your network.
When you enable network accounting for CEF from global configuration mode, accounting information
is collected at the Route Processor (RP) when CEF mode is enabled and at the line cards when distributed
CEF (dCEF) mode is enabled. You can then display the collected accounting information using the show
ip cef privileged EXEC command.
non-recursive Enables accounting through nonrecursive prefixes.
This keyword is optional when used in global configuration mode.
per-prefix (Optional) Enables the collection of the number of packets and bytes
express forwarded to a destination (or prefix).
prefix-length (Optional) Enables accounting through prefix length.
external Counts input traffic in the nonrecursive external bin.
internal Counts input traffic in the nonrecursive internal bin.
