Question
Refer to the exhibit. An engineer must send the 172.16.2.0 /24 user traffic to a packet capture tool to troubleshoot an issue. Which action completes the configuration?
Options
- ADefine the remote span VLAN on SW1 and SW2.
- BDisable the spanning tree protocol on the monitoring server VLAN.
- CEncrypt the traffic between the users and the monitoring servers.
- DEnable the Cisco Discovery Protocol on the server interfaces.
Explanation
To capture user traffic on a separate device, Remote SPAN (RSPAN) is the appropriate solution, which requires a dedicated VLAN for transporting mirrored traffic.
Common mistakes.
- B. Disabling Spanning Tree Protocol (STP) on any VLAN can lead to Layer 2 loops and network instability, and it is unrelated to the process of mirroring traffic for analysis.
- C. Encrypting traffic between users and monitoring servers would obscure the packet contents, making it impossible for a packet capture tool to troubleshoot issues effectively.
- D. Cisco Discovery Protocol (CDP) is used for device discovery and information exchange between directly connected Cisco devices, not for mirroring user traffic to a capture tool.
