Ta b l e 31 show ip cef switching statistics Field Descriptions
Field Description
Path Switching path of the particular feature. Switch paths are platform-dependent.
Following are example switch paths for the Cisco 7200 series router:
• RIB—process switching with Cisco Express Forwarding assistance
• (low-end switching [LES])—Cisco Express Forwarding switch path
• PAS—Cisco Express Forwarding turbo switch path
Following are example switch paths for the Cisco 7500 series router:
• RIB—centralized process switching with Cisco Express Forwarding assistance
• LES—centralized Cisco Express Forwarding switch path on the Route/Switch
Processor (RSP)
• RSP—centralized Cisco Express Forwarding turbo switch path on the RSP
• Slot NN—distributed Cisco Express Forwarding turbo switch path on the Versatile
Interface Processor (VIP) in the indicated slot number
Feature Feature that returned the statistics.
Reason Packet description.
Consume Number of packets that the feature removed from the switch path (and will probably
reintroduce to the switch path later). For example, with crypto with hardware
acceleration, the feature might queue the packets to encryption and decryption; because
hardware (and software) encryption is time-consuming, these packets are queued so the
main processor can begin handling the next packet while the crypto module processes the
removed packet. Also, for example, the feature might queue the packets for process
switching through a private queue for that feature.
Drop Number of packets dropped.
Punt Number of packets that could not be switched in the normal path and were punted to the
next-fastest switching vector.
Punt2Host Number of packets that could not be switched in the normal path and were punted to the
host.
For switch paths other than a centralized turbo switch path, punt and punt2host function
the same way. With punt2host from a centralized turbo switch path (PAS and RSP), punt
will punt the packet to LES, but punt2host will bypass LES and punt directly to process
switching.
New i/f Number of packets for which the feature provided Cisco Express Forwarding with
forwarding information (that is, bypassed the normal route lookup).
Command Description
show cef interface Displays Cisco Express Forwarding-related interface information.
show ip cef Displays entries in the FIB.
show ip route Displays router advertisement information received from onlink routers.
