Parameters
interval-in-minutes: Interval (in minutes) to collect topology information, ranging from 0 to 65,535. A
value of 0 disables topology information collection.
Description
Use the ntdp timer command to configure the interval to collect topology information periodically.
Use the undo ntdp timer command to restore the default interval.
By default, this interval is one minute.
After the interval is set to a non-zero value, the switch will collect topology information periodically at this
interval. You can also use the ndp explore command to start a topology collection process manually.
Note that:
z
Only the management switch can collect topology periodically, and a member switch cannot.
However, you can use the ndp explore command on the member switch to start a topology
collection process manually.
z
After a cluster is set up, the management switch will collect the topology information of the network
at the topology collection interval you set and automatically add the candidate switches it discovers
into the cluster.
z
If you do not want the candidate switches to be automatically added into the cluster, you can set the
topology collection interval to zero, and use the add-member command to add the candidate
switches to the cluster manually.
Examples
# Set the topology collection interval to 30 minutes.
<aaa_0.Sysname> system-view

undo ntdp timer hop-delay
View
System view
Parameters
time: Device forwarding delay in milliseconds. This argument ranges from 1 to 1,000.
Description
Use the ntdp timer hop-delay command to set the delay for devices to forward topology collection
requests.
Use the undo ntdp timer hop-delay command to restore the default device forwarding delay.
By default, the device forwarding delay is 200 ms.
