Field Name	Description


Port Mode	The operational mode of the port or ports on the
	module. Not all modules support all modes. Both
	sides of the link must be in the same mode. Flow
	Control and ISL (Interswitch Link) are
	recommended for backbone links with Lucent
	Technologies’ equipment. Note that the Port Speed
	field will be insensitive if the Use Switches field is
	set to ON.
	The components which make up the mode are:
	• Half Duplex (HDX) - The port operates in Half
		Duplex.
	• Full Duplex (FDX) -The port operates in Full
		Duplex and doubles its speed. No repeaters are
		allowed in the path.
	• Flow Control (FC) - Flow Control is a
		proprietary mechanism that prevents packet loss
		on the link due to congestion in the Full Duplex
		mode.
	• Interswitch Link (ISL) - Interswitch Link is a
		proprietary mechanism to tag packets with
		VLAN and priority information across the
		backbone. This allows two Lucent devices to act
		as a single logical entity.
	The possible modes are:
	•	Half Duplex (HDX)
	•	Full Duplex (FDX)
	• Full Duplex and Flow Control (FDX+FC)
	• Full Duplex and Interswitch Link
		(FDX+ISL)
	• Full Duplex, Flow Control, and Interswitch
		Link (FDX+FC+ISL)

Port Speed	The Ethernet speed of the port. Port speed can be
	either Ethernet (10 Mbps), Fast Ethernet (100
	Mbps), or Gigabit Ethernet (1000 Mbps). Some
	units have
	10BaseT/100BaseTX ports, where each port can
	work in either 10Mbps or 100Mbps.
