Usage Guidelines

Usage Scenario

If a large number of NS messages are sent to a main control board, the CPU usage of the main control board may be high. To resolve this issue, run the nd fast-reply enable command to enable ND fast reply. After the command is run, NS messages are sent to an interface board instead of a main control board, and the interface board responds with NA messages.

Example

# Enable ND fast reply on the board in slot 1.

<HUAWEI> system-view
[~HUAWEI] slot 1
[~HUAWEI-slot-1] nd fast-reply enable
