Usage Guidelines Use the show interfaces switching command to show which path the router uses and how the traffic is
switched. This command is also useful for troubleshooting CPU utilization.
Statistics for packets in, bytes in, packets out, and bytes out are displayed for the available protocols.
The statistics are arranged by process, cache misses, fast-path, and autonomous path. All values
displayed by the show interfaces switching command are absolute. The clear interface counters
command has no effect on these values.
You must enter at least seven characters of the switching keyword (switchi) when you use the show
interfaces switching command.
