Parameters
time: Port forwarding delay in milliseconds. This argument ranges from 1 to 100.
Description
Use the ntdp timer port-delay command to configure the topology request forwarding delay between
two ports, that is, the interval at which the device forwards the topology requests through the
NTDP-enabled ports one after another.
Use the undo ntdp timer port-delay command to restore the default port forwarding delay.
By default, the port forwarding delay is 20 ms.
Network congestion may occur if large amount of topology response packets reach the collecting
device in a short period. To avoid this case, after a collected switch forwards a received topology
collection request through a port, it delays for a period before it forwards the request through the next
port. You can use the ntdp timer port-delay command to set the delay.
You can use the command on a collecting switch. The delay value you set by the ntdp timer port-delay
command is carried in the topology collection requests sent by the collecting switch, and is used by
collected devices to determine the topology collection request forwarding delay between two ports.
Examples
# Set the port forwarding delay for collected switches to forward NTDP requests to 40 ms.
