Nortel Networks 4050 manual Link is transferred back to the primary port

Table 100 Interface fields (continued)
Field	Description
Mode	Specifies the mode of operation for the port numbers
	assigned to this interface. The options are:
	• failover — only one link is active at any given time. If the
	port with an active link fails, the active link is
	immediately switched over to one of the other ports
	configured for the interface. When you select failover
	mode, you also have the option of specifying a primary
	port.
	• trunking — active links are sustained on all configured
	ports simultaneously, in order to increase network
	throughput.
	The default is failover.
Primary Port	Specifies the primary port in the interface, on which the
	active link is set up. If the primary port fails, the active link
	is immediately transferred to a remaining (secondary) port.
	As soon as the primary port regains functionality, the active
	link is transferred back to the primary port.
	An integer indicating the port number of the physical port
	assigned to the interface. The default is 0 (zero).
	The default value of zero means that the currently active
	link remains in use until it fails. If the port fails, the link is
	transferred to another port. The link remains active on the
	port to which it was transferred, even after the failed port
	regains functionality.
	The primary port setting applies only when you have
	configured more than one port in the interface, and the
	mode is failover.
