Configuring a Management IP Interface

CN4093 Application Guide for N/OS 8.3
Each switch in a stack can be configured with the external management IP interface
(127). The switch's MAC address must be associated with the management IP
interface. This interface can be used for connecting to and managing the switch
externally. Follow the steps below:
CN 4093(config)# interface ip 127
CN 4093(config-ip-if)# mac <switch MAC address> ip address <IPv4 address> <subnet
mask> enable
CN 4093(config-ip-if)# exit
CN 4093(config)# ip gateway 3 mac <switch MAC address> address <gateway IPv4
address> enable
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:
CN 4093(config-if)# 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.
