Reconfiguring ALOM to Use the Network Management Port

By default, ALOM uses the serial management port (SERIAL MGT) to communicate with an external terminal or other ASCII device. If desired, you can reconfigure ALOM to use the Ethernet network management (NET MGT) port, and then you can connect to ALOM through telnet.

The NET MGT port accommodates a standard RJ-45 connector. For information about how to establish the hardware connections between the NET MGT port and your network, refer to your server's documentation.

Note: When you connect a terminal device to the NET MGT port, the server must be connected to a 10-Mbit network. ALOM does not support 100-Mbit or 1-Gbit networks.

To configure the ALOM software to communicate using the NET MGT port, you need to specify values for the network interface variables. There are three ways to specify values for these variables:

Run the setupsc script from the sc> prompt.
Set values for each individual variable from the sc> prompt using the setsc command.
Set values for each individual variable from the system console using the scadm set command.

Running the setupsc Script

At the sc> prompt, type the following command:

sc> setupsc

The setup script starts.

To exit the script and save the changes you have made, type Ctrl-Z. To exit the script without saving any changes, type Ctrl-C.

For example, the script starts as follows:

sc> setupsc
Entering interactive script mode. To exit and discard changes to that point, use Ctrl-C or to exit and save changes to that point, use Ctrl-Z.

If desired, you can customize all of the ALOM configuration variables at once by following the interactive questions in the script. To configure only the network interface variables, press Return at each prompt until the following prompt is displayed:

Do you wish to configure the enabled interfaces [y]?

Follow this procedure at the above prompt to configure the network interface variables:

Type y to confirm that you want to configure the network interface variables.

The setupsc script returns the following prompt:

Should the SC network interface be enabled?
Type true or press Return to enable the network interface, or type false to disable it. This sets a value for the if_network variable.
Follow the interactive questions in the script. The script prompts you to set values for the following variables:
- if_modem -- specify false
- netsc_dhcp
- netsc_ipaddr
- netsc_ipnetmask
- netsc_ipgateway
- netsc_tpelinktest
When you have finished setting up the network interface variables, type Ctrl-Z to save your changes and exit the setupsc script. If desired, you can finish configuring all of the ALOM configuration variables.
Before you can use your network configuration, you need to reset ALOM. You can do this in one of two ways:
- At the sc> prompt, type the resetsc command.
- At the superuser prompt in the system console, type the scadm resetrsc command.

Using the setsc Command to Set the Network Interface Variables

You can set values for the network interface variables from the sc> prompt using the setsc command. You issue the command once for each variable you would like to configure. For example:

sc> setsc if_network true
sc> setsc netsc_enetaddr 0a:2c:3f:1a:4c:4d
sc> setsc netsc_ipaddr 123.123.123.123

You need to specify values (or use the default values) for each of the following variables:

Using the scadm set Command to Set the Network Interface Variables

You can set values for the network interface variables from the superuser (#) prompt in the system console using the scadm set command. You issue the command once for each variable you would like to configure. For example:

# scadm set if_network true
# scadm set netsc_enetaddr 0a:2c:3f:1a:4c:4d
# scadm set netsc_ipaddr 123.123.123.123

You need to specify values (or use the default values) for each of the following variables:
