Operation
Configure the aging timer for
NDP information
The NDP information of the adjacent device must be updated periodically to
ensure that the switch can update the local NDP neighbor information table in
time after the configuration of the adjacent device is changed. You can configure
the interval at which NDP packets are sent by using the following command.
Table 667 Configure the interval at which NDP packets are sent
Operation
Enter system view
