Monitoring IPSec

This section contains information about troubleshooting and monitoring IPSec.

System Event Logs

To troubleshoot and monitor IPSec, use the following system event logs:

auditIpsec—Lower layers of IKE SA negotiations
ikepki—Upper layers of IKE SA negotiations
stTunnel—Secure tunnel interface

For more information about using event logs, see the JUNOSe System Event Logging Reference Guide.

show Commands

To view your IPSec configuration and to monitor IPSec tunnels and statistics, use the following show commands.

show ipsec ike-policy-rule

show ike policy-rule

Note: The show ipsec ike-policy-rule command replaces the show ipsec isakmp-policy-rule command, which may be removed completely in a future release.
