Uninstalling the Update

Uninstalling the Update from Devices Deployed Inline

Managed devices do not perform traffic inspection, switching, routing, or related 

functions while the update is being uninstalled. Depending on how your devices 

are configured and deployed, the uninstallation process may also affect traffic 

flow and link state. For more information, see 

 on page 4.

Uninstalling the Update from Sourcefire Software for X-Series

You must uninstall the update from each VAP group individually in order to fully 

uninstall the update from Sourcefire Software for X-Series. Uninstalling the 

Version 5.3.0.2 update of the Sourcefire 3D System reloads the affected VAP. If 

your Sourcefire Software for X-Series is deployed inline and you are using 

multi-member VAP groups, Sourcefire recommends that after you uninstall the 

update from a VAP, you allow that VAP to reload before you uninstall the update 

from additional VAPs.
This allows the other VAPs in the group to inspect network traffic while the 

affected VAP 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 uninstallation for a maintenance window or other time when it 

will have the least impact on your deployment.

After the Uninstallation

After you uninstall the update, there are several steps you should take to ensure 

that your deployment is performing properly. These include verifying that the 

uninstall succeeded and that all appliances in your deployment are 

communicating successfully.
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.

Uninstalling the Update from a Managed Device

The following procedure explains how to use the local web interface to uninstall 

the Version 5.3.0.2 update from managed devices. You cannot use a Defense 

Center to uninstall the update from a virtual managed device.
Uninstalling the Version 5.3.0.2 update results in a device running Version 5.3. For 

information on uninstalling a previous version, refer to the release notes for that 

version.
Uninstalling the Version 5.3.0.2 update reboots the device. Managed devices do 
not perform traffic inspection, switching, routing, or related functions during the 

update. Depending on how your devices are configured and deployed, the update 

process may also affect traffic flow and link state. For more information, see
