This section describes how to configure whitelist session-CAR for dual-device backup to isolate bandwidth resources per session for active/standby protocol packets.
Whitelist session-CAR for dual-device backup isolates bandwidth resources per session for active/standby protocol packets transmitted between the master and backup devices. This configuration prevents packets over different active/standby protocol sessions from preempting bandwidth resources. You can adjust whitelist session-CAR bandwidth parameters if the defaults do not meet service requirements.
The system view is displayed.
Bandwidth parameters of whitelist session-CAR are adjusted for dual-device backup.
If an excessive number of dual-device backup protocol session packets are sent to the CPU, you can adjust parameters to ensure that the packets are properly sent to the CPU. In normal cases, you are advised to use the default values of these parameters.
In IPv6 scenarios, you can run the whitelist session-car rbs-ipv6 { cir cir-value | cbs cbs-value | pir pir-value | pbs pbs-value } * command instead.
Whitelist session-CAR is disabled for dual-device backup.
By default, whitelist session-CAR for dual-device backup is enabled. You need to disable whitelist session-CAR only when it is abnormal, preventing this function from affecting the sending of dual-device backup protocol packets to the CPU. In normal circumstances, enabling whitelist session-CAR for dual-device backup is recommended.
The configuration is committed.
