Packet Capture Commands
Packet capture commands assist in troubleshooting protocol-related problems with the
management CPU. The packets to and from the management CPU can be captured in an
internally allocated buffer area for export to a PC host for protocol analysis. Public domain
packet analysis tools like Ethereal can be used to decode and review the packets in detail.
Capturing can be performed in a variety of modes, either transmit-side only, receive-side only,
or both. The number of packets captured will depend on the size of the captured packets.
