If a banner is configured, the banner page is displayed when you access the Web user interface - HP 6120XG | ProCurve Series 6120 Blade Switches Management and Configuration Gui - Page 49
(if configured). Following entry of the correct username/password information (or if no username/password is required), the switch then displays either the Registra tion page or the switch's home page. Note that if the banner feature is disabled or if the switch is using the factory-default banner - HP 6120XG | ProCurve Series 6120 Blade Switches Management and Configuration Gui - Page 50
banner is not seen on the standby module, only the active module. Example of Configuring and Displaying a Banner Suppose a system operator wanted to configure the following banner message on her company's switches: This is a private system maintained by the Allied Widget Corporation. Unauthorized - HP 6120XG | ProCurve Series 6120 Blade Switches Management and Configuration Gui - Page 51
can result in civil and criminal penalties! Figure 2-5.

Manager or ProCurve Manager Plus The next time someone logs onto the switch's management CLI, the following appears: The login screen displays the configured banner. Entering a correct password clears the banner and displays the CLI prompt. Figure 2-7. Example of CLI Result of the Login Banner - HP 6120XG | ProCurve Series 6120 Blade Switches Management and Configuration Gui - Page 53
only when the switch is in the factory default configuration. Using no banner motd deletes the currently configured banner text and blocks display of the default banner. The default banner is restored only if the switch is reset to its factorydefault configuration. ■ The switch supports one banner - HP 6120XG | ProCurve Series 6120 Blade Switches Management and Configuration Gui - Page 54

Guaranteed Minimum Bandwidth (GMB) Syntax: [ no ] int < port-list > bandwidth-min output Configures the default minimum bandwidth allocation for the outbound priority queue for each port in < port-list >. The default values per priority queue are: • Queue 1 (low priority): 2% • Queue 2 (low priority - HP 6120XG | ProCurve Series 6120 Blade Switches Management and Configuration Gui - Page 333
total bandwidth for each outbound queue. The queues receive service in descending order of priority. You must specify a queues in descending order of priority. For example, if you configure a minimum of 10% for queues 1 support traffic bursts above its guaranteed minimum.

-min setting. If packets are sent to a queue configured at 0%. lower priority queues can be starved and not reach their guaranteed minimum bandwidth setting. The switch applies the bandwidth calculation to the link speed the port is currently using.
