5.2.7
Learn more about the changes to default behavior in Prisma
SD-WAN ION device release 5.2.7.
Keep the following upgrade and downgrade considerations
in mind when upgrading or downgrading your devices to and from Release
5.2.7.
If you are on a 4.x release, to upgrade to Release 5.2.7,
you must first upgrade to Release 5.0.1 or Release 5.0.3.
To rollback or downgrade to Release 4.x, you must downgrade
first to Release 5.0.3 or Release 5.0.1.
Note the following upgrade considerations per feature.
Prioritized Interface List to Establish Controller
Connection
Starting with Release 5.2.7, the Prisma SD-WAN
ION will now use the following prioritized interface list when establishing
a controller connection:
LAN Interfaces
WAN Interfaces sorted by cost from lowest to highest.
Optimizations to Minimize Application Sessions
Starting
with Release 5.2.7, to minimize application sessions using an Layer
3 Failure Path, several optimizations have been performed. These
optimizations include:
Increasing the VPN-to-VPN asymmetry
window from 5 seconds to 120 seconds.
In addition to tracking when an active or backup path comes
up, the system will periodically attempt to move flows from L3 Failure
to active or backup paths every 30 minutes.
Moving flows that are on an Layer 3 failure path of any path
type (Direct, Prisma SD-WAN VPN, Third-party VPN) to an active or
backup path once available. Previously only Layer 3 failure paths
of type Prisma SD-WAN VPN would be eligible to move flows to active
or backup Prisma SD-WAN VPN paths once available.
