Field		Description
Unit		This field only appears if the switch is participating in a stack configuration. The field
		allows you to select the number of the unit you want to view. To view another unit, type its
		unit number and press [Enter], or press the spacebar on your keyboard to toggle the unit
		numbers.
Port		Indicates the switch port numbers that correspond to the field values in that row of the
		screen (for example, the field values in row 2 apply to switch port 2). Note that the values
		in the Switch row affect all switch ports and, when the switch is part of a stack, the values
		in the Stack row affect all ports in the entire stack.
Trunk		The read-only data displayed in this column indicates the trunks that correspond to the
		switch ports specified in the Trunk Members fields of the Trunk Configuration screen
		(see “MultiLink Trunk Configuration Menu screen” on page 133).
