Verifying the Master Blocking Sensor Configuration
To verify that a master blocking sensor is set up properly or to troubleshoot a master blocking sensor
that is not set up properly, you can use the show statistics network-access command. Make sure that
the forwarding sensor is set up as TLS trusted host if the remote master blocking sensor is using TLS for
web access.
