Before You Begin: Important Update and Compatibility Notes

regardless of how you configured any inline sets, switching, routing, NAT, and 

VPN are not performed during the update process. 

.

Network Traffic Management

Managed devices do not perform switching, routing, NAT, VPN, or related 

functions during the update. If you configured your devices to perform only 

switching and routing, network traffic is blocked throughout the update.

Product Compatibility

You must use at least Version 5.2 of the Defense Center to manage Version 
5.2.0.5 devices. Defense Centers running Version 5.2.0.5 can manage devices 

running Version 5.2 or greater.

Web Browser Compatibility

Version 5.2.0.5 of the web interface for the Sourcefire 3D System has been 

tested on the browsers listed in the following table.

Network Traffic Interruption

Inline with 

configurable bypass
(Failopen option 

enabled for inline 

sets)

Network traffic is interrupted at two points during the update:
• At the beginning of the update process, traffic is briefly interrupted while 

link goes down and up (flaps) and the network card switches into hardware 

bypass. Traffic is not inspected during hardware bypass.

• After the update finishes, traffic is again briefly interrupted while link flaps 

and the network card switches out of bypass. After the endpoints reconnect 

and reestablish link with the sensor interfaces, traffic is inspected again. 

 The configurable bypass option is not supported on non-bypass 

NetMods on 8000 Series devices, or SFP transceivers on 71xx Family devices.

Inline

Network traffic is blocked throughout the update.

Passive

Network traffic is not interrupted, but also is not inspected during the update.
