Field Name	Description


Port STA State	The state of the port in terms of the Spanning Tree
	Protocol. The possible states are:
	• Disabled - The port is disabled.
	• Blocking - STP is enabled and currently
		blocking the port. This means that the port is
		effectively disabled to prevent the formation of a
		loop in the network.
	• Forwarding - The port is currently forwarding
		information received.
	For more information refer to Spanning Tree
	Algorithm (STA) on page 27 of The Reference Guide.

Port Type	The port type; optionally includes reference to the
	module to which it is attached and port connector
	type.

Position	The position of the main and backup agent (either
	1 or 2) within the device.

Propagate Status	The state of status propagation on the port or
	module. When enabled, the status of a port or
	module is passed up one level.
	For example, when the Propagate Status field of a
	problematic port is enabled, the port’s icon as well
	as the module that the port is located on appears
	red. If Propagate Status is disabled, only the port
	icon appears red.
	The following colors indicate the status of the port
	or module:
	•	Red - Fatal
	• Grey - Disabled (port only)
	•	Yellow - Warning
	•	Green - Okay
	By default, status propagation is enabled for all
	ports and modules.

S/W Port Redundancy	The state of the port redundancy function between
	two ports. Possible states are on and off.

S/W Version	The version of the application software running on
	the module or agent.
