VPN Log
The VPN log captures diagnostic messages relating to VPN tunnels to help troubleshoot and monitor
VPN configurations. Each log entry is tab-delimited. The log fields are populated based on the type of
event being logged. If a field is not used, a tab is inserted to properly position the data in the next field.
To maintain a complete history of entries and provide a backup, you can configure the X family device
to send VPN Log entries to a syslog server from the Syslog Servers page. For details, see
Syslog
Servers” on page 242.
A VPN log entry contains the following fields:

configuring the Enable Verbose messages in the VPN Log option available on the IPSec Configuration
