To reduce the risk of being attacked by malicious users against opened socket and
enhance switch security, the Switch 4210 provides the following functions, so that
a cluster socket is opened only when it is needed:
■ Opening UDP port 40000 (used for cluster) only when the cluster function is
implemented,
■ Closing UDP port 40000 at the same time when the cluster function is closed.
On member devices, the preceding functions are implemented as follows:
Set the holdtime of member
switches
holdtime seconds Optional
By default, the holdtime is 60
seconds.
Set the interval to send
handshake packets
timer interval Optional
By default, the interval to
send handshake packets is 10
seconds.
