On-box packet sniffing monitors and analyzes network traffic on ports without using an external device, such as collector or an agent. Use this feature to reduce costs and simplify debugging.
On-box packet sniffing allows you to monitor IPv4 packets on ingress or egress ports, matching them based on header attributes like source IP, destination IP, source MAC, destination MAC, VLAN, and VNID. You can store the sniffed packets in pcap format. We've introduced the following configuration statements to support this feature:
