Parameters
interval: Interval (in seconds) to send handshake packets. This argument ranges from 1 to 255.
Description
Use the timer command to set the interval between sending handshake packets.
Use the undo timer command to restore the default value of the interval.
By default, the interval between sending handshake packets is 10 seconds.
In a cluster, the management device keeps connections with the member devices through handshake
packets. Through the periodic handshaking between the management and member devices, the
management device monitors the member status and link status.
Note that, you need only execute the command on a management device, which will advertise the
handshake interval setting to all member devices in the cluster.
Examples
# Set the interval to send handshake packets to 3 seconds.
