Cisco Cisco Firepower Management Center 2000

The update process begins. You can begin monitoring the update's progress in the task queue (

). However, after the Defense Center completes its necessary pre-update checks, 

you are logged out. When you log back in, the Upgrade Status page appears. The Upgrade Status page 
displays a progress bar and provides details about the script currently running.

If the update fails for any reason, the page displays an error message indicating the time and date of the 
failure, which script was running when the update failed, and instructions on how to contact Support. Do 
not restart the update.

If you encounter any other issue with the update (for example, if a manual refresh of the Update Status 
page shows no progress for several minutes), do not restart the update. Instead, contact Support.

When the update completes, the Defense Center displays a success message and reboots.

The update process begins. You can monitor the update's progress in the task queue (

).

Do not use the web interface to perform any other tasks until the update completes and the Defense 
Center reboots. Before the update completes, the web interface may become unavailable and the Defense 
Center may log you out. This is expected behavior; log in again to view the task queue. If the update is 
still running, do not use the web interface until the update completes. If you encounter issues with the 
update (for example, if the task queue indicates that the update has failed or if a manual refresh of the 
task queue shows no progress for several minutes), do not restart the update. Instead, contact Support.

After the update finishes, clear your browser cache and force a reload of the browser. Otherwise, the user 
interface may exhibit unexpected behavior.

Log into the Defense Center.

Review and accept the End User License Agreement (EULA). Note that you are logged out of the 
appliance if you do not accept the EULA.

Select 

 and confirm that the software version is listed correctly: Version 5.3.1.3. Also note 

the versions of the rule update and VDB on the Defense Center; you will need this information later.

Verify that the appliances in your deployment are successfully communicating and that there are no 
issues reported by the health monitor.

If the rule update available on the Support site is newer than the rules on your Defense Center, import 
the newer rules.

For information on rule updates, see the FireSIGHT System User Guide.

If the VDB available on the Support site is newer than the VDB on your Defense Center, install the latest 
VDB.

Installing a VDB update causes a short pause in traffic flow and processing, and may also cause a few 
packets to pass uninspected. For more information, see the FireSIGHT System User Guide.

Reapply device configurations to all devices.

To reactivate a grayed-out 

 button, edit any interface in the device configuration, then click 

 

without making changes.

Reapply access control policies to all devices.

Do not reapply your intrusion policies individually; you must reapply all access control policies 
completely.
