Step 6 Clear the packets from the buffer by entering:
Switch# monitor capture mycap clear
Step 7 Confirm that the buffer is now empty by entering:
Switch# show monitor capture mycap buffer brief
Wait about 10 seconds.
Step 8 Display the buffer contents.
Switch# show monitor capture mycap buffer brief
Step 9 Restart the traffic, wait about 10 seconds, then display buffer contents by entering:
Switch# show monitor capture mycap buffer brief

Step 10 Store the buffer contents to the mycap1.pcap file in the internal bootflash: storage device.
Switch# monitor capture mycap export bootflash:mycap1.pcap
Exported Successfully
Step 11 Check that the file has been created and that it contains the packets by entering:
Switch# dir bootflash:mycap1.pcap
Directory of bootflash:/mycap1.pcap
