Updating Your Appliances

one at a time. This allows the other VAPs in the group to inspect network traffic 

while the VAP that is being updated reloads. If you are using single-VAP VAP 

groups in an inline deployment, reloading the VAP causes an interruption in 

network traffic. Make sure you plan the update for a maintenance window or 

other time when it will have the least impact on your deployment.

After the Installation

After you perform the update on either the Defense Center or managed devices, 

you must reapply device configuration and access control policies. Applying an 

access control policy may cause a short pause in traffic flow and processing, and 

may also cause a few packets to pass uninspected. For more information, see the 

Sourcefire 3D System User Guide.
There are several additional post-update steps you should take to ensure that 

your deployment is performing properly. These include:

verifying that the update succeeded

making sure that all appliances in your deployment are communicating 

successfully

updating your intrusion rules, if necessary

updating your vulnerability database (VDB) to at least version 220

making any required configuration changes based on the information in 

The next sections include detailed instructions not only on performing the update, 

but also on completing any post-update steps. Make sure you complete all of the 

listed tasks.

Updating a Defense Center

Use the procedure in this section to update your Defense Centers, including 

virtual Defense Centers. For the Version 5.3.0.3 update, Defense Centers reboot.

Before you update the Defense Center, reapply access control 

policies to any managed devices. Otherwise, the eventual update of the managed 

device may fail.

Do not reboot or shut down your appliances during the update until 

after you see the login prompt. The system may appear inactive during the 

pre-checks portion of the update; this is expected behavior and does not require 

you to reboot or shut down your appliances.
