Enabling subinterface rate statistics collection on a serial interface
![[IMPORTANT: ]](images/important.png) | IMPORTANT: This feature is resource intensive. When you enable this feature, make sure you fully understand its impact on system performance. | |
After enabling subinterface rate statistics collection on a serial interface, the device periodically refreshes the rate statistics for the subinterfaces of the serial interface. You can use the display interface command to view the rate statistics.
Serial interfaces that support this feature include synchronous serial interfaces and sub-channel serial interfaces.
To enable subinterface rate statistics collection for a serial subinterface:
Step | Command | Remarks |
|---|---|---|
1. Enter system view. | system-view | N/A |
2. Enter serial interface view. | interface serial interface-number | N/A |
3. Enable subinterface rate statistics collection on the serial interface. | sub-interface rate-statistic | By default, subinterface rate statistics collection on the serial interface is disabled. |
