What command is used to fetch the IPsec statistics for a tunnel?

The command used to fetch the IPsec statistics for a tunnel is "get vpn ipsec stats tunnel." This command is specifically designed to provide detailed statistics related to IPsec VPN tunnels, including information such as the number of packets sent and received, errors, and other performance metrics.

Using this command allows network administrators to monitor the health and performance of IPsec tunnels, identify potential issues, and ensure that the VPN connections are functioning optimally. It offers a direct approach tailored to VPN configurations, enabling targeted troubleshooting and management of VPN tunnels within the firewall environment.

The other commands listed do not fulfill this specific purpose effectively. "Show ipsec statistics" may suggest broader statistics but lacks the specificity regarding tunnels. "Get ipsec performance" implies performance metrics but not necessarily focused on statistics for individual tunnels. "Display tunnel stats" could refer to various aspects of network tunnels but does not directly relate to IPsec VPN statistics specifically. Hence, the first command is the most appropriate and precise for retrieving the relevant statistics for an IPsec tunnel.
