Follow these steps to enable NTDP globally and for specific ports:
To do… Use the command… Remarks
Enter system view system-view —
Enable NTDP globally ntdp enable
Optional
Enabled by default
Enter Ethernet interface view or
Layer 2 aggregate interface view
interface interface-type
interface-number
—
Enable NTDP for the port ntdp enable
Optional
NTDP is enabled on all ports by
default.
NOTE:
HP recommends that you disable NTDP on a
port which connects with the devices that do not need to join
the cluster. This prevents the management switch from adding and collectin
topolo
y information from
devices which do not need to join the cluster.
Configuring NTDP parameters
By configuring the maximum hops for collecting topology information, get topology information of the
devices in a specified range, avoiding unlimited topology collection.
After the interval for collecting topology information is configured, the device collects the topology
information at this interval.
To avoid network congestion caused by large amounts of topology responses received in short periods,
perform the following steps:
• Upon receiving an NTDP topology-collection request, a device does not forward it immediately.
Instead, it waits for a period of time and then forwards the NTDP topology-collection request on its
first NTDP-enabled port.
• Except for its first port, each of a device’s NTDP-enabled ports wait for a period of time, and then
forward the NTDP topology collection request after the previous port forwards it.
Follow these steps to configure NTDP parameters:
To do… Use the command… Remarks
Enter system view system-view —
Configure the maximum hops for
topology collection
ntdp hop hop-value
Optional
3 by default.
Configure the interval to collect
topology information
ntdp timer interval
Optional
1 minute by default.
Configure the delay to forward
topology-collection request packets
on the first port
ntdp timer hop-delay delay-time
Optional
200 ms by default.
Configure the port delay to forward
topology-collection request on
other ports
ntdp timer port-delay delay-time
Optional
20 ms by default.
