Use the following commands to monitor the status and display statistics for the Interprocessor Communication
(IPC) messages between the RP and line card:
clear time-range ipc
Used to clear the time-range IPC message statistics and counters between the RP and the line card.
debug time-range ipc
Used to enable debugging output for monitoring the time-range IPC messages between the RP and the line
card.
show time-range ipc
Used to display the statistics about the time-range IPC messages between the RP and the line card.
Turbo ACLs
Traditional ACLs are searched sequentially (top-down) to find matching criteria. As the ACLs grow, a significant
amount of time and memory can be consumed for lookups when packets are being processed. This adds a
variable latency to the packet forwarding and results in performance issues. The Turbo ACL feature is designed
to process ACLs more efficiently to improve router performance. This feature is available on high-end platforms
such as the Cisco 7200 and 7500 series routers and the Cisco 12000 series Gigabit Switch Routers (GSR).
The Turbo ACLs feature compiles the ACLs into a group of lookup tables while maintaining the first match
requirements.
