If you are running a pre-5.4.1 Prisma
SD-WAN ION device version, the aggressive and non-aggressive mode
settings configured on the circuit will take affect. If VPN keep-alive
timers were changed using the advanced UI, they will continue to
take affect until the device is upgraded to release 5.4.1 or later.
Pre-5.4.1 circuits with non-aggressive mode settings are
automatically translated to non-aggressive mode keep-alive settings
with Keep-Alive Interval - 30,000 ms and Keep-Alive Failure Count
- 3, when controller upgrades to Release 5.4.1.
Pre-5.4.1 circuits with aggressive mode settings, which are
the default settings, inherit settings from the Circuit Category
level, when controller upgrades to Release 5.4.1. The Circuit Category
level, by default, has the aggressive mode keep-alive settings (Keep-Alive
Interval - 1000 ms and Keep-Alive Failure Count - 3).
