Parameters
time: Delay time (in milliseconds) for a switch to forward topology-collection request
packets. This argument ranges from 1 to 1,000 and defaults to 200.
Description
Use the ntdp timer hop-delay command to set the delay time for a switch to forward
topology-collection request packets.
Use the undo ntdp timer hop-delay command to restore the default delay time.
To avoid network congestion caused by a large amount of topology response packets
received by the topology collection device in a short period, a switch delays for specific
period before it forwards a received topology-collection request packet through its first
ports. You can use the ntdp timer hop-delay command to set the delay time.
These two commands are intended for switches that collect topology information. They
actually set the hop-delay value for topology-collection request packets sent by these
switches. The hop-delay value determines the delay time for a switch receiving
topology-collection request packets to forward them through its first port.
Examples
# Set the delay time for the switch to forward topology-collection request packets
through the first port to 300 ms.
