Parameter 
Interval: Interval (in seconds) to send handshake packets. This argument ranges from 1 
to 255. 
Description 
Use the timer command to set the interval to send handshake packets. 
Use the undo timer command to restore the default value of the interval. 
By default, the interval to send handshake packets is 10 seconds.  
Inside a cluster, the connections between member devices and the management 
device are kept through transmitting handshake packets. Handshake packets in a 
cluster enable the management device to acquire the information about member states 
link states. 
Execute these two commands on management devices only. All the member devices in 
a cluster acquire the handshake interval setting from the management device. 
Example 
# Configure the interval to send handshake packets to be 3 seconds.
