Chapter 2 HGMP V2 Configuration
Commands
2-14
Use the
undo ntdp timer hop-delay
command to restore the default device forwarding
delay.
By default, the device forwarding delay is 200 ms.
Network congestion may occur if large amount of topology response packets reach the
collecting device in a short period. To avoid this case, each collected switch in the
network delays for a period before it forwards a received topology collection request
through each NTDP-enabled port.
You can use the
ntdp timer hop-delay
command to set the delay on a collecting switch.
The delay value you set by the command is carried in the topology collection requests
sent by the collecting switch, and is used by collected devices to determine how long
they should wait before they can forward the received topology collection requests.
Examples
# Set the delay for collected switches to forward topology collection requests to 300 ms.

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
