Use the undo ntdp enable command to disable NTDP globally or on a port.
By default, NTDP is enabled both globally and on ports.
Note that NTDP can take effect on a port only when NTDP is enabled both globally and on the port.
Examples
# Enable NTDP globally, and then enable NTDP on port Ethernet 1/0/1.

Description
Use the ntdp explore command to manually start a topology collection process.
NTDP is able to periodically collect topology information. In addition, you can use this command to
manually start a topology collection process at any moment. If you do this, NTDP collects NDP
information from all devices in a specific network range (which can be set through the ntdp hop
command) as well as the connection information of all its neighbors. Through this information, the
management device or the network management software knows the topology in the network range,
and thus it can manage and monitor the devices in the range.
Examples
