Prior to configuring, you must be connected to the switch Command Line Interface
(CLI) as the administrator.
Note: For details about accessing and using any of the menu commands described
in this example, see the Lenovo N/OS Command Reference.
In the example topology in
used:
Table 33.

Subnet Devices
1 Primary and Secondary Default
Routers
2 First Floor Client Workstations
3 Second Floor Client Workstations
4 Common Servers
Since there are four IP subnets connected to the switch, four IP interfaces are
needed:

IP interfaces are configured using the following commands:
CN 4093(config)# interface ip 1
CN 4093(config-ip-if)# ip address 205.21.17.3 255.255.255.0 enable
CN 4093(config-vlan)# exit
CN 4093(config)# interface ip 2
CN 4093(config-ip-if)# ip address 100.20.10.1 255.255.255.0 enable
CN 4093(config-ip-if)# exit
CN 4093(config)# interface ip 3
CN 4093(config-ip-if)# ip address 131.15.15.1 255.255.255.0 enable
CN 4093(config-ip-if)# exit
CN 4093(config)# interface ip 4
CN 4093(config-ip-if)# ip address 206.30.15.1 255.255.255.0 enable
CN 4093(config-ip-if)# exit
