Ntdp Timer - H3C s3600 series Command Manual

Parameters
hop-value: Maximum hops to collect topology information, namely, the topology collection range, in the
range of 1 to 16.
Description
Use the ntdp hop command to set the topology collection range.
Use the undo ntdp hop command to restore the default topology collection range.
By default, the topology collection range is three hops.
With the ntdp hop command, you can specify to collect topology information from the devices within a
specified range to avoid infinite collection. That is, you can limit the range of topology collection by
setting the maximum hops from the collecting device to the collected devices. For example, if you set
the maximum hops to two, the switch initiating the topology collection collects topology information from
the switches within two hops.
Note that:
The topology collection range set by this command is applicable to both the periodic and manual
topology collection.
This command is only applicable to topology-collecting device, and a wider collection range
requires more memory of the topology-collecting device.
Examples
# Set the topology collection range to 5 hops.
<aaa_0.Sysname> system-view
System View: return to User View with Ctrl+Z.
[aaa_0.Sysname] ntdp hop 5

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.
