Usage Guidelines
This command applies to control path packets; not datapath packets. Packets can be retrieved through the tar log
command; look for the filter.pcap file. This command activates packet capture options on the current switch. They
are not saved and applied across switches.
If you do want to enable a packet capture session without setting values that can be saved and used for another
session, use the command packet-capture. The related command
packet capture options that will run every time you enable the packet capture feature.
Example
