Table K-13	Advanced Interface Settings Dialog Box
Element		Description
Interface		The interface on which the advanced settings are defined. Enter the name of
		an interface or interface role, or click Select to display an Object Selectors,
		page F-593.
		If the interface role you want is not listed, click the Create button in the
		selector to display the Interface Role Dialog Box, page F-464. From here
		you can create an interface role object.
		Note You can define only one set of advanced settings per interface.
		Note The only advanced settings supported on Layer 2 interfaces are Max.
			Bandwidth, Load Interval, and CDP.
Max Bandwidth		The bandwidth value to communicate to higher-level protocols in kilobits
		per second (kbps).
		Note The value you define in this field is an informational parameter only;
			it does not affect the physical interface.
Load Interval		The length of time, in seconds, used to calculate the average load on the
		interface. Valid values range from 30 to 600 seconds, in multiples of 30
		seconds. The default is 300 seconds (5 minutes).
		Modify the default to shorten the length of time over which load averages are
		computed. You can do this if you want load computations to be more reactive
		to short bursts of traffic.
		Load data is gathered every 5 seconds. This data is used to compute load
		statistics, including input/output rate in bits and packets per second, load,
		and reliability. Load data is computed using a weighted-average calculation
		in which recent load data has more weight in the computation than older load
		data.
		Tip	You can use this option to increase or decrease the likelihood of
			activating a backup interface; for example, a backup dial interface
			may be triggered by a sudden spike in the load on an active interface.
		Note Load interval is not supported on subinterfaces.
