Usage Information Use the tcpdump command to perform a packet capture on a specified switch CPU: Control Processor (CP) or Route Processor (RP). You can use the capture-duration timer and the packet-count counter at the same time. The TCP dump stops when the first of the thresholds is met. That means that even if the duration timer is 9000 seconds, if the maximum file count parameter is met first, the dumps stop. Debugging and Diagnostics 799
