Usage Guidelines

Usage Scenario

In prefix allocation scenarios, after the function of saving PD routes to a file is enabled, to reduce the impact on the system, the device writes the PD route user table into a file after a delay of 5 minutes when the entries are fully written into the non-volatile random access memory (NVRAM) by default. The delay can be configured based on the number of online users.

Example

# Set a delay for writing the PD route user table into a file during automatic file saving to 10 minutes.
