In FortiGate, which command is best used to check the status of an IPsec VPN tunnel?

• A. show ipsec stats
• B. get vpn ipsec tunnel
• C. get vpn status
• D. show interfaces

Answer: (B)

To check the status of an IPsec VPN tunnel in FortiGate, the command to use is "get vpn ipsec tunnel." This command provides detailed information about the current status of IPsec tunnels, including their state (up, down, etc.), the details about the peers, and the encryption/decryption statistics. It is specifically designed to focus on VPN tunnel statuses, making it the most relevant and direct command for this task. Using this command allows network administrators to quickly assess the operational health of the VPN infrastructure, diagnose issues, and ensure that the tunnels are functioning as expected. The data provided helps in real-time monitoring and troubleshooting of VPN connections. Other commands, while they may provide useful information, do not specifically focus on the IPsec VPN tunnel status. For instance, "show ipsec stats" might present statistics related to IPsec traffic but won't clearly indicate the state of the tunnels themselves. "get vpn status" is a broader command that may not provide the specific details for IPsec tunnels. Lastly, "show interfaces" reveals information about network interfaces but is not pertinent to IPsec VPN tunnel status tracking.
