Switch#
Example: Capture and Store in Lock-step Mode
This example captures live traffic and stores the packets in lock-step mode to achieve a high capture rate.
Note The capture rate might be slow for the first 15 seconds. If possible and needed, start the traffic 15 seconds
after the capture session has started.
Step 1 Define a capture point to match on the relevant traffic and associate it to a file by entering:
Switch# monitor capture mycap interface gi 3/1 in match ipv4 any any
Switch# monitor capture mycap limit duration 60 packets 100
Switch# monitor cap mycap file location bootflash:mycap.pcap buffer-size 64
Step 2 Confirm that the capture point has been correctly defined by entering:
Switch# show monitor capture mycap parameter
monitor capture mycap interface GigabitEthernet3/1 in
monitor capture mycap match ipv4 any any
monitor capture mycap file location bootflash:mycap.pcap buffer-size 64
monitor capture mycap limit packets 100000 duration 60
Switch# show monitor capture mycap
