Which packet capture method allows FortiSwitch to capture traffic on trunks and management interfaces?

FortiSwitch supports packet capture through various methods, but the Sniffer profile is specifically capable of capturing traffic on both trunks and management interfaces. Here's why:

Sniffer Profile (B):

Versatile Capture:The sniffer profile in FortiSwitch is designed to capture traffic across different types of interfaces, including trunks (where multiple VLANs are present) and management interfaces (used for controlling and monitoring the switch).

Configuration Flexibility:You can configure sniffer profiles to target specific traffic, offering flexibility in monitoring and troubleshooting network issues on both data and management planes.

Other Options:

SPAN (A)is used mainly for mirroring traffic to another port for analysis but is typically limited in its ability to capture management interface traffic.

sFlow (C)andTCP dump (D)are useful tools but do not specifically align with the capability to universally capture traffic across trunks and management interfaces in the context described.
