Motorola P880 manual Parameter Definition

port that does support auto-negotiation. If two gigabit ports that support auto-negotiation are connected, you should enable auto-negotiation.

—Auto-negotiation and remote fault detection cannot be enabled concurrently. Auto-negotiation must be disabled in order to enable remote fault detection. When auto- negotiation is enabled, remote fault detection is automatically disabled.

—For gigabit modules, auto-negotiation is always disabled.

	Table 9. Gigabit Port Parameters
Parameter	Definition
Name	A user-assigned name for this port (possibly a drop
	name or the name of the station or other device
	connected to the port).
Category	Enables you to select either User Port or Service
	Port. The User Port is intended for use with
	switch connections to end user nodes. The
	Service Port is intended for use with switch
	connections to servers or other switches.
	The primary difference between the User and
	Service Port designation is that a Service Port
	allows the switch to generate both log messages and
	alarm messages (traps). The User Port only
	generates log messages. This prevents your
	network management station from being
	overwhelmed by port up/down messages that
	result from users turning workstations on and off.
Flow	Determines if IEEE 802.3z pause control is used
Control	on this port. The pause mechanism allows the port
Mode	to stop a sending station from sending more
	packets if the receiving port’s buffers are full. This
	helps prevent lost or dropped packets.
	This feature is recommended for use primarily on
	end station connections. Using this feature on
	trunk ports can cause unnecessary congestion on
	the network.
