Installing a Sourcefire 3D System Appliance
Testing an Inline Bypass Interface Installation
Chapter 3
8. Shut down the device:
• On a Series 2 device, type
sudo su -, then type your password again.
At the root prompt, shut down the appliance by typing
shutdown -h
now
.
• On a Series 3 device, type
system shutdown.
You can also shut down the device using its web interface; see the Managing
Devices chapter in the Sourcefire 3D System User Guide. As most devices
power off, they emit an audible click sound. The click is the sound of relays
switching and the device going into hardware bypass.
9. Wait 30 seconds.
Verify that your ping traffic resumes.
10. Power the device back on, and verify that your ping traffic continues to pass.
11. For appliances that support tap mode, you can test and record ping latency
results under the following sets of conditions:
• device powered off
• device powered on, policy with no rules applied, inline intrusion policy
protection mode
• device powered on, policy with no rules applied, inline intrusion policy
protection tap mode
• device powered on, policy with tuned rules applied, inline intrusion
policy protection mode
Ensure that the latency periods are acceptable for your installation. For
information on resolving excessive latency problems, see Configuring Packet
Latency Thresholding and Understanding Rule Latency Thresholding in the
Sourcefire 3D System User Guide.
