Use this variable to specify the ALOM IP (Internet Protocol) netmask.
From the ALOM command shell:
Using the scadm utility:
The default IP address supplied by this variable is 255.255.255.0 (Class C network).
Note: If you are using DHCP to obtain your ALOM network configuration, you do not need to set this variable. If netsc_dhcp is set to true, then the setupsc script does not ask you to set netsc_ipnetmask.
A typical IP address contains four sets of numbers between 0 and 255, separated by decimal points. This is referred to as standard dot notation.
If the IP address you specify does not work with the subnet mask and ALOM IP addresses you specify, ALOM returns the following error message, substituting the values for netsc_ipgateway and netsc_ipaddr:
Error: Invalid IP netmask for IP address <netsc_ipaddr> and IP gateway <netsc_ipgateway>.
Check that all the values you entered are correct. If you need help obtaining the correct IP address, ask your network administrator.
