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 large amount of topology response packets
received in short periods, 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.
Example
# Set the delay time for the switch to forward topology-collection request packets
through the first port to 300 ms.

Parameter
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 switch to forward a
received topology-collection request packet through its successive ports. A switch
forwards received topology request packets to all its ports in turn. After forwarding a
received topology-collection request packet through one port, the switch delays for
specific period before it forwards the packet through the next port.
