Parameter 
interval-in- minutes: Interval (in minutes) to collect topology information, ranging from 0 
to 65,535.  This argument defaults to 0, which specifies not to collect topology 
information. 
Description 
Use the ntdp timer command to configure the interval to collect topology information. 
Use the undo ntdp timer command to restore the default interval. 
B y default, the interval to collect topology information is 1 minute.  
A switch collects topology information once in each period set by the ntdp timer 
command. 
Note that: 
z  The (disable) prompt in the timer field of the display ntdp command means that 
the device is not the member of the cluster and does not perform periodical 
topology collection. 
z  After the cluster is set up, the S3900 switch will collect the topology information in 
the network at the set interval and add the detected candidate switches into the 
cluster automatically.  
z  If it is unnecessary to add the candidate switches into the cluster automatically, 
you can set the interval of topology collection to 0.  
Example 
# Set the interval to collect topology information to 30 minutes.
