Updating Your Appliances
Defense Centers do not receive software updates as part of the regular
synchronization process.
To ensure continuity of operations, do not update paired Defense Centers at the
To ensure continuity of operations, do not update paired Defense Centers at the
same time. First, complete the update procedure for the secondary Defense
Center, then update the primary Defense Center.
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
applies it to the secondary device, which goes into maintenance mode until any
necessary processes restart and the device is processing traffic again. The
system then applies the update to the primary device, which follows the same
process.
Installing the Update on Stacked Devices
When you install an update on stacked devices, the system performs the updates
simultaneously. Each device resumes normal operation when the update
completes. Note that:
•
If the primary device completes the update before all of the secondary
devices, the stack operates in a limited, mixed-version state until all devices
have completed the update.
•
If the primary device completes the upgrade after all of the secondary
devices, the stack resumes normal operation when the update completes
on the primary device.
Installing the Update on Clustered Stacks
When you install an update on a clustered stack, the system performs the update
one stack at a time. When the update starts, the system first applies it to the
one stack at a time. When the update starts, the system first applies it to the
secondary stack, which goes into maintenance mode until any necessary
processes restart and the stack is processing traffic again. The system then
applies the update to the primary stack, which follows the same process.
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.
