NOTES:
You must have administrator privileges to change the values for a property.
The list of available properties for your particular adapter may be different.
Some properties may not be available for all Broadcom network adapters.
If an adapter is included as a member of a team and you change any advanced property, then you must rebuild the team to ensure that the
team's advanced properties are properly set.
To set adapter properties
1. Click the name of the adapter in the Device Management pane.
2. Click the Configurations tab. If the Configurations tab is not visible, then from the View menu, select Navigate, then Device Management, and
then Configurations.
3. From the Advanced or iSCSI Boot Configuration section, select the property you want to set. If the Advanced or iSCSI Boot Configuration
section is not available, then from the Context View tab on the right side of the window, select Configurations and then select Advanced or
iSCSI Boot Configuration.
4. To change the value of a property, select an item from the property's list or type a new value, as appropriate (selection options are different for
different properties).
5. Click Apply to confirm the changes to all properties. Click Reset to return the properties to their original values. Click Defaults to restore all
settings to their default values.
NOTES:
Clicking Reset after clicking Defaults, but before clicking Apply, will purge all values.
Apply must be clicked to make changes go into effect.
Any changes to existing settings will be lost upon clicking Defaults.
