The Networking 6th Generation Switch ASIC based module creates compatibility between v2 and v3 blades on the 5400R Chassis Switches. When the 5400R Chassis Switch platform detects a mix of v2 and v3 blades, the v3 feature will default the platform to v2 behavior. The default behavior is v2.

The compatibility mode of v2 and v3 modules are controlled by configuration. When the compatibility mode is disabled, v2 modules in the system will be disabled.
