4.2.7.3.4 Change UI IP Authorization Status
The User Administration / Authorized IP / Change UI IP Authorization Status screen permits toggling (that is, alternating) the state of authorization list between ‘enabled’ and ‘not enabled.’
When this menu option is chosen, the current authorization state is displayed in the INFO field.
Figure 4-46 Change UI IP Authorization Status Screen
If the authorization state is 'NOT Enabled’, click the Enable IP Checking button to toggle the state to 'Enabled'.
In the example above, the figure shows the authorization state is ‘NOT Enabled.’ To toggle the state to Enabled, click the Enable IP Checking button. See Figure 4-47 for an example of the authorization status having been successfully toggled to the opposite state, now ‘Enabled.’
Figure 4-47 Toggling the UI IP Authorization Status
The enforcement of the checking for authorization status is immediate. The IP address of every message of every IP device using the GUI is checked as soon as the authorization status is enabled. The checking for authorized IPs does not occur only when devices log in.
