Final answer:
The 'get vpn ipsec tunnel details' command retrieves active VPN tunnel details, including status and performance metrics, but not configurations, encryption keys, or protocol versions.
Step-by-step explanation:
When the get vpn ipsec tunnel details command is used, it retrieves active VPN tunnel details. This includes information such as the number of packets encrypted and decrypted, the number of packets that bypassed encryption, the current state of the tunnel, the tunnel uptime, and any errors that have been detected. It does not provide detailed IPSec tunnel configurations, encryption key details, or IPSec protocol versions but rather focuses on the status and performance metrics of existing tunnels.
