CN4093 Application Guide for N/OS 8.2
To provide continuous Management IP reachability in the event of a Master node
failover, an additional floating Management IP address can be set up on the
management interface. The floating Management IP address will be used by the
backup switch when taking over management from the failed master node. To
configure the floating Management IP address, use the following command:
CN4093(config­if)# floating ip address <IPv4 address> <subnet mask>
Note: The Management IP and floating Management IP addresses on the master
switch, as well as the Management IP address on the backup switch, must be in
the same subnet.
Note: In case of a stack split, the floating IP cannot be used anymore due to
duplicate IP address issue.
Once the stack links are connected, access the internal management IP interface of
the Master switch (assigned by the management system) and complete the
configuration.
