Onboard Packet Capture tool allows quick capture of packets received or transmitted on a front panel port. The captured packets are stored in one or more Packet Capture (PCAP) files for debugging.
After capturing the configured number of packets, packet capturing process automatically stops for that particular interface. To save and retrieve packet capture in a PCAP file, packet capture must be stopped globally. Saving packet capture configurations in a config file is not required as packet capture is intended for live debugging for a short period of time only.
The packet capture CLI commands are allowed in the Exec mode. The show capture packet config command displays all packet capture configurations on Ethernet ports. The show capture packet interface command displays content of the PCAP file when packet capture is in-progress. For more information, see Extreme 9920 Software Command Reference, 21.2.2.0 .
