CAUTION: NDP Config settings will be restored to defaults if the Switch
is restarted and you have not selected Save Config from the
main menu and saved your running configuration to non-

NOTE: The NDP functions are effective only when NDP is enabled
Globally and for at least one Port.
NOTE: The Aging Time should be set higher than the Hello Time value.
15.2 NTDP
NTDP (Neighbor Topology Discovery Protocol) is used by the Commander to collect
NDP information. NTDP packets transmit and forward NTDP topology information col-
lection requests based on the NDP Neighbor Information Table. The information is then
collected and the NDP information and neighboring connection information of each
device in a specified Network range is recorded. The Commander collects the specified
Topology in the Network regularly. You can also enable Topology Collection Manually
on the Commander Switch.
After the Commander Switch sends out NTDP request packets the Member Switches
receive the request packets and send out response packets. This can result in Network
congestion and Commander Switch overload. To avoid this, 2 Time Parameters are
designed to control the spread of NTDP request packets.
„
NTDP Hop Delay: The amount of time between the Switch receiving the NTDP
request packets and the Switch forwarding NTDP response packets for the first time.
„
NTDP Port Delay: The amount of time between the Port forwarding NTDP request
packets and its adjacent Port forwarding NTDP request packets.
The NTDP function can be implemented on NTDP Device Table, NTDP Summary and
NTDP Config pages.
