The whitelist session-car rbs-ipv4 disable command disables CAR for IPv4 RBS sessions.
The undo whitelist session-car rbs-ipv4 disable command enables CAR for IPv4 RBS sessions.
By default, CAR for IPv4 RBS sessions is enabled.
Usage Scenario
By default, CAR for IPv4 RBS sessions is enabled to isolate IPv4 RBS packets by session. This prevents packets of different IPv4 RBS sessions from preempting bandwidth resources from one another. If CAR for IPv4 RBS sessions is abnormal, you can run the whitelist session-car rbs-ipv4 disable command to disable this function so that IPv4 RBS packets can be sent to the CPU properly. Under normal circumstances, enabling CAR for IPv4 RBS sessions is recommended.
