High Speed Flow Control Configuration

Table 3-12.	Port Configuration Screen Fields (continued)

Field	Description

Port	Indicates the switch port numbers that correspond to the field values in that row of
	the screen (for example, the field values in row 2 apply to switch port 2). The values
	that you set in the Switch row will affect all switch ports and, when the switch is part
	of a stack, the values that you set in the Stack row will affect all ports in the entire
	stack (except the gigabit MDA ports or fiber optic ports, when installed).
Trunk	The read-only data displayed in this column indicates the trunks that correspond to
	the switch ports specified in the Trunk Members fields of the Trunk Configuration
	screen (see “MultiLink Trunk Configuration” on page 3-37).
Status	Allows you to disable any of the switch ports. You can also use this field to control
	access to any switch port.
	Default Value	Enabled
	Range	Enabled, Disabled
Link	A read-only field that indicates the current link state of the corresponding port, as
	follows:

•Up: The port is connected and operational.

•Down: The port is not connected or is not operational.

Autonegotiation	When enabled, sets the corresponding port speed to match the best service provided
	by the connected station, up to 100 Mb/s in full-duplex mode. This field is disabled for
	all fiber optic ports.
	Default Value	Enabled
	Range	Enabled, Disabled
Speed/Duplex1	Allows you to manually configure any port to support an Ethernet speed of 10 Mb/s or
	100 Mb/s, in half- or full-duplex mode. This field is set (by default) to 1000 Mb/s,
	full-duplex for gigabit ports only.
	Default Value	100Mbs/Half (when Autonegotiation is Disabled)
	Range	10Mbs/Half, 10Mbs/Full, 100Mbs/Half, 100Mbs/Full

1 Fiber optic ports can only be set to 100 Mb/s/Half or 100 Mb/s Full.

The High Speed Flow Control Configuration screen (Figure 3-15) allows you to set the port parameters for installed gigabit MDAs.

Note: This screen only appears when an optional gigabit MDA is installed in the Uplink Module slot.
