Cisco 10000 Series Router Performance Routing Engine Installation
OL-3971-03
Analyzing and Troubleshooting Packets
The following example output provides packet information before sending the 100 packets. Notice that
the Packets Denied field indicates that no packets have been denied by ACL 108. The Denied and Log
field indicates that no denied packets have been logged.
Router# show pxf cpu statistics security
ACL PktsPktsDeniedPermit
NameDeniedPermitted& Log& Log
1080000
The following example output results after sending the 100 packets. Notice that the Packets Denied field
now indicates that 100 packets have been denied. Recall that the router denied the packets because they
matched the implicit deny statement. This statement does not include a log keyword, which causes
information to be sent to the console. Therefore, no logging occurs. Notice that the Denied and Log field
correctly indicates this.
Router# show pxf cpu statistics security
ACL PktsPktsDeniedPermit
NameDeniedPermitted& Log& Log
108 100 0 0 0
Displaying IP Forwarding Statistics
The show pxf cpu statistics ip command provides statistical information about IP forwarding. The
following example output indicates the count of the IP forwarding counter before sending the 100
packets. Notice that the count is 402.
Router# show pxf cpu statistics ip
FP ip statistics
dropped0
forwarded402
punted540
