Quidway S3500 Series Ethernet Switches Chapter 2 HGMP V2 Configuration Commands

Description
Using ntdp timer hop-delay command, you can configure delay for collected device to
forward topology collection request. Using undo ntdp timer hop-delay command, you
can restore the default delay value.
To avoid network congestion resulted from collecting device’s receiving large amount of
responses simultaneously, you can configure each collected device to delay response
for a period of time after receiving the topology request. Then, the first port will start to
forward the topology request packet.
This command is executed on the collecting device. The topology request contains the
hop-delay time, according to which the collected device decides how long it shall wait
before the first port forwards the request.
Example
# Configure that the collected device receives NTDP request and delays for 300ms
before transmitting the NTDP packet to the first port.

Description
Using ntdp timer port-delay command, you can configure the delay before the next
port’s forwarding packets on the collected device. Using undo ntdp timer port-delay
command, you can restore the default port-delay.
