On AWS and Azure, dataplane interfaces use socket-based networking instead of UNIC modules. After upgrading a version later than 12.1.0, the default module for dataplane interfaces is UNIC modules instead of socket-based networking.
The raw socket-based tmm driver is replaced by a UNIC driver. The socket-based driver eliminates kernel driver dependencies and provides better portability during kernel/driver upgrades.
Upgrading BIG-IP VE on AWS or Azure running versions 12.0.0 or 12.1.0.
None.
BIG-IP VE socket-based networking driver retained after upgrade on AWS or Azure.
