TP-Link TL-SG5412F User Manual

The following entries are displayed on this screen:
 Global Config
NDP: Select Enable/Disable NDP function globally.
Aging Time: Enter the period for the neighbor switch to keep the NDP packets
from this switch.
Hello Time: Enter the interval to send NDP packets.
 Port Config
Select: Select the desired port to configure its NDP status.
Port: Displays the port number of the switch.
NDP: Displays NDP status of the current port.
Enable: Click the Enable button to enable NDP for the port you select.
Disable: Click the Disable button to disable NDP for the port you select.
Note:
1. NDP function is effective only when NDP function is enabled globally and for the port.
2. The aging time should be set over the hello time value, otherwise the neighbor information
table of NDP ports will be unstable
14.2 NTDP
NTDP (Neighbor Topology Discovery Protocol）is used for the commander switch to collect NDP
information. NTDP transmits and forwards NTDP topology collection request based on NDP
neighbor information table, and collects the NDP information and neighboring connection
information of each device in a specific network range. The commander switch can collects the
specified topology in the network regularly and you can also enable topology collection manually
on the commander switch.
After the commander switch sends out NTDP request packets, lots of switches receive the request
packets and send out response packets at the same time, which may result in network congestion
and the commander switch overload. To avoid the above problem, two time parameters are
designed to control the spread speed of NTDP request packets.
 NTDP hop delay: Indicates the time between the switch receiving NTDP request packets and
the switch forwarding NTDP request packets for the first time.
 NTDP port delay: Indicates the time between the port forwarding NTDP request packets and its
adjacent port forwarding NTDP request packets over.
The NTDP function can be implemented on Device Table, NTDP Summary and NTDP Comfit
pages.
14.2.1 Device Table
On this page you can view the information of the devices collected by NTDP. Meanwhile, no matter
whether a cluster is established, on this page you can manually collect NTDP information at any
time to manage and control devices.
