OpenBoot PROM Variables
Before you issue the boot net command from the OpenBoot PROM prompt (OK), verify that
the local-mac-address? variable is set to false. This setting is the factory default setting. If the
variable is set to true, you must ensure that this value is an appropriate local conguration.
Caution A local-mac-address? that is set to true might prevent the domain from successfully
booting over the network.
In a netcon window, you can use the following command at the OpenBoot PROM prompt to
display the values of the OpenBoot PROM variables:
OK printenv
To reset the local-mac-address? variable to the default setting. use the setenv command:
OK setenv local-mac-address? false
