Parameters
time: Delay time (in milliseconds) for a switch to forward a topology-collection request
packet through its successive ports. This argument ranges from 1 to 100 and defaults to
20.
Description
Use the ntdp timer port-delay command to set the delay time for a port (on the device
whose topology information is collected) to wait to forward topology-collection request
packets after the last port (on the device whose topology information is collected)
forwards topology-collection request packets.
Use the undo ntdp timer port-delay command to restore the default delay time.
By default, the delay time of a port is 20 ms.
To avoid network congestion caused by a large amount of topology response packets
received by the topology collection device in short periods, a switch delays for a specific
period before it forwards a received topology-collection request packet through the next
port. You can use the ntdp timer port-delay command to set the delay time.
These two commands are intended for switches that collect topology information. They
actually set the port-delay value for topology-collection request packets sent by these
switches. The port-delay value determines the delay time for a switch receiving
topology-collection request packets to forward them through the next port.
Examples
# Set the delay time for the switch to forward topology-collection request packets
through the successive ports to 40 ms.
