Usage Guidelines

Usage Scenario

If the receiving switch does not receive NDP packets from a switch when the aging time of the NDP packets on the receiving switch expires, the receiving switch automatically deletes the neighbor entry corresponding to the switch.

Prerequisites

The ndp timer aging command takes effect only after NDP is enabled on the device.

Precautions

The aging time of the NDP packets on the receiving switch must be greater than the interval for sending NDP packets.

Example

# Set the aging time of entries in the NDP table to 175 seconds.
