Field	Description
Operation Mode	Read-only field that indicates the operation mode of the unit, for example:
	• When the unit is part of a stack configuration, the (read-only) field indicates the
	unit is operational in a stack, and lists the current unit number of this switch. In
	this example (see Figure 43 on page 101), the current unit number is Unit 2.
	• When the unit is not part of a stack configuration (operating standalone), the
	read-only field indicates the unit is operating as a switch. When in this operation
	mode, the Size of Stack and Base Unit fields (see following description) do not
	appear.
Size of Stack	This read-only field only appears when the switch is participating in a stack
	configuration. This field indicates the number of units configured in the stack
	configuration (1 to 8 units maximum).
Base Unit	This read-only field only appears when the switch is participating in a stack
	configuration. This field indicates the unit number of the switch that is currently
	operating as the base unit.
MAC Address	The MAC address of the switch or, when the switch is participating in a stack
	configuration, the MAC address of the stack configuration.
