Set the Management IP Address of the Fabric

Language:

To use the fabric's management interface remotely, you must configure an IP address and prefix length for the interface. You initially configure these parameters when you first run the installation wizard at the console port. If you have changes to your management network, you might need to change the IP address you use for the fabric.

You can perform this task using either the CLI or the GUI. For the GUI procedure, refer to Discover Devices in Oracle Fabric Manager 5.0.2 Administration Guide. This procedure is for the CLI.

(Optional) Check the current settings.

If other administrators manage virtual I/O, check if anyone is logged in.
```
[OFOS] show login
```

If other users are logged on, send a system broadcast to warn them of the change.
For example:
```
[OFOS] system broadcast Changing management IP to 192.168.10.97 in 2 minutes!
```
Note - Changing the system management address can affect management connectivity to the fabric for other administrators and for management systems. If you are connected remotely, this command breaks that connection.
If you have a leaf switch that is running version 1.0, follow these steps to change the IP address.
1. Log in to the chassis as the root user.
```
hostname login: root
Password:password
Last login: Fri Mar 25 09:51:36 on ttyS0
[root@hostname ~]#
```
  The default password is changeme.
2. Start the nm3tool.
```
[root@hostname ~]# nm3tool
```
  For more information about using the nm3tool, refer to Updating the Firmware in Oracle EDR InfiniBand Switch and Virtualized I/O Systems Administration Guide.
3. At the Main Menu, select 1 to change the IP address.
  You can also change the host name or perform a chassis upgrade.
4. Type the new IP address.
5. Type q to exit the menu.
6. Reboot the SCP.
```
[root@hostname ~]# reboot 
```
If you have a virtualization switch, follow these steps to change the IP address.
The following commands are supported on Oracle Fabric OS 1.0.1 and 1.0.2. You can set a static or DHCP IP address.

For example, to set a static IP address:
```
[OFOS] set system management-interface -address 192.168.3.56
```
Use the set system ipconfig dhcp command to set a DHCP IP address. For more information, refer to set system in Oracle Fabric OS 1.0.2 Command Reference.

(Optional) Verify that the new IP address is active.
