The whitelist session-car pim disable command disables the PIM whitelist Session-CAR function.
The undo whitelist session-car pim disable command restores the PIM whitelist Session-CAR function.
By default, the PIM whitelist Session-CAR function is enabled.
Usage Scenario
By default, the PIM Session-CAR function is enabled, which isolates packet channels between PIM sessions. To disable this function on a device, run the whitelist session-car pim disable command. After the configuration, PIM packets received by the device are directly sent to the CPCAR channel. If the device receives a large number of PIM packets in this case, packets from different PIM sessions may preempt bandwidth resources. Therefore, disabling this function is not recommended in normal cases.
Precautions
To check whether CAR for whitelisted PIM sessions is supported on each board, run the display cpu-defend whitelist session-car pim statistics slot command.
