1-30 

seconds: Neighbor information holdtime in seconds, ranging from 1 to 255. 

Use the holdtime command to configure the neighbor information holdtime of the member switches. 

Use the undo holdtime command to restore the default holdtime value. 

By default, the neighbor information holdtime is 60 seconds. 

Note that: 

z 

If the management switch does not receive NDP information from a member device within the 

holdtime, it sets the state of the member device to “down”. When the management device receives 

the NDP information from the device again, the device will be re-added to the cluster automatically. 

z 

If the management device receives NDP information form a member device within the holdtime, the 

member device stays in the normal state and does not need to be added to the cluster again. 

z 

Note that, you need only execute the command on a management device, which will advertise the 

holdtime value to all member devices in the cluster. 

# Set the neighbor information holdtime of the cluster members to 30 seconds.
