Usage Guidelines

Usage Scenario

By default, the switch performs user-level rate limiting on the users connecting to all interfaces. If you are sure that the users connecting to an interface are secure, you can disable user-level rate limiting on this interface.

Precautions

Before using this command, run the cpu-defend host-car enable command to enable user-level rate limiting.
After user-level rate limiting is disabled on an interface, the switch does not limit the rate of packets received from the specified user MAC address and cannot protect the interface against attacks. In addition, the packets of the same type sent from other users may be affected.

Example

# Disable user-level rate limiting on the interface.
