Troubleshooting Blocking

Note

ARC was formerly known as Network Access Controller. Although the name has been changed since
IPS 5.1, it still appears in IDM, IME, and the CLI as Network Access Controller,

nac

, and

network-access

.

After you have configured ARC, you can verify if it is running properly by using the

show version

command. To verify that ARC is connecting to the network devices, use the

show statistics

network-access

command.

To troubleshoot ARC, follow these steps:

1.

Verify that ARC is running.

2.

Verify that ARC is connecting to the network devices.

3.

Verify that the Event Action is set to Block Host for specific signatures.

4.

Verify that the master blocking sensor is properly configured.

For More Information

Verifying ARC is Running

To verify that ARC is running, use the

show version

command. If MainApp is not running, ARC cannot

run. ARC is part of MainApp. To verify that ARC is running, following these steps:

Step 1

Log in to the CLI.

Step 2

Verify that MainApp is running.
