Saving captured packets to a file configuration example

On Device A, capture 10 incoming packets on Ten-GigabitEthernet 1/0/1, save the packets to a packet file, and display contents in the file.

# Capture packets on Ten-GigabitEthernet 1/0/1. Set the maximum number of captured packets to 10. Save the packets to the file flash:/a.pcap.

<DeviceA> packet-capture interface ten-gigabitethernet 1/0/1 limit-captured-frames 10 write flash:/a.pcap
