(Optional) Configuring Whitelist Session-CAR for PCEP
You can configure whitelist session-CAR for PCEP to isolate bandwidth resources by session for PCEP packets. This configuration prevents bandwidth preemption among PCEP sessions in the case of a traffic burst.
Context
When the PCEP service suffers a traffic burst, bandwidth may be preempted among PCEP sessions. To resolve this problem, you can configure whitelist session-CAR for PCEP to isolate bandwidth resources by session. If the default parameters of whitelist session-CAR for PCEP do not meet service requirements, you can adjust them as required.
Procedure
- Run system-view
The system view is displayed.
- Run whitelist session-car pcep-ipv4 disable
CAR for whitelisted PCEP sessions is disabled.
Disable this function only if it encounters an exception. In normal cases, you are advised to keep this function enabled.
- (Optional) Run whitelist session-car pcep-ipv4 { cir cir-value | cbs cbs-value | pir pir-value | pbs pbs-value } *
Parameters of whitelist session-CAR for PCEP are configured.
- Run commit

Verifying the Configuration
After configuring whitelist session-CAR for PCEP, you can verify the configuration.
Run the display cpu-defend whitelist session-car pcep statistics slot slot-id command to check whitelist session-CAR statistics about PCEP packets on a specified interface board.
To check the statistics in a new period of time, you can run the reset cpu-defend whitelist session-car pcep statistics slot slot-id command to clear the existing statistics about whitelist session-CAR for PCEP on the specified interface board; after a certain period of time, run the display cpu-defend whitelist session-car pcep statistics slot slot-id command.
Cleared whitelist session-CAR statistics cannot be restored. Exercise caution when running the reset command.
