Use the ndp enable command to enable NDP on a port.
Use the undo ndp enable command to disable NDP on a port.
When this command is used in Ethernet port view, the interface keyword cannot be
provided and the NDP feature is enabled on the current port only.
By default, NDP is enabled both globally and on a port.
Note that the NDP feature on a port does not take effect until the NDP feature is
enabled globally.

1.1.3 ndp timer aging
Syntax
ndp timer aging aging-in-seconds
undo ndp timer aging
View
System view
Parameters
aging-in-seconds: Holdtime (in seconds) to be set of the NDP information sent by the
local switch. This argument ranges from 5 to 255.
The default holdtime is 180 seconds.
Description
Use the ndp timer aging command to set the holdtime of the NDP information sent by
the local switch, that is, to specify how long a device will hold the NDP packets received
from the local device. After the aging timer expires, the device removes the received
NDP neighbor node information.
Use the undo timer aging command to restore the default NDP information holdtime.
You can specify how long an adjacent device will hold the NDP information sent by the
local device. An adjacent device holds the NDP information of the local switch
according to the holdtime carried in the NDP packets received from the local switch and
removes the NDP information when the aging timer expires.
