Sourcefire 3D System Release Notes

Updating Your Appliances

after rebooting; this is expected behavior. If you encounter issues with the 

progress of your update, contact Sourcefire Support.

 

Configuration and Event Backup Guidelines

Before you begin the update, Cisco strongly recommends that you back up 

current event and configuration data to an external location. This data is not 

backed up as part of the update process.
You can use the Defense Center to back up event and configuration data for itself 

and the devices it manages. For more information on the backup and restore 

feature, see the Sourcefire 3D System User Guide.

Sourcefire does not support updating or reimaging appliances with 

more than one hard drive. You must remove additional hard drives before 

beginning the update.

When to Perform the Update

Because the update process may affect traffic inspection, traffic flow, and link 

state, Cisco strongly recommends you perform the update in a maintenance 

window or at a time when the interruption will have the least impact on your 

deployment.

Installation Method

Use the Defense Center’s web interface to perform the update. Update the 

Defense Center first, then use it to update the devices it manages.
Although you can install a managed device update from its local web interface, 

Cisco strongly recommends using the Defense Center, especially for older or less 

powerful managed device models.

Order of Installation

Update your Defense Centers before you update the devices they manage.

Installing the Update on Clustered Devices

When you install an update on clustered devices, the system performs the 

update on the devices one at a time. When the update starts, the system first
