Command Manual - Integrated Management
Quidway S2000 Series Ethernet Switches
Description
Using ntdp timer command, you can configure the topology collection interval. Using
undo ntdp timer command, you can restore the default topology collection interval.
By default, the interval of periodic topology collection is 0 minute, i.e. no regular
topology collection will be performed.
In order to learn the topology changes in time, it is necessary to regularly collect the
topology information throughout the whole scope specified. This can show any
topological changes, some of which may be omitted by the partial collection.
Example
# Configure the periodic topology connection interval is 30 minutes.

Parameter
time: The time that the collected device wait before forwarding the topology-collection
request, ranging from 1 to 1000 milliseconds. By default, the value is 200ms.
Description
Using ntdp timer hop-delay command, you can configure delay for collected device to
forward topology collection request. Using undo ntdp timer hop-delay command, you
can restore the default delay value.
To avoid network congestion resulted from collecting device's receiving large amount of
responses simultaneously, you can configure each collected device to delay response
for a period of time after receiving the topology request. Then, the first port will start to
forward the topology request packet.
