Interface Commands (Cont.)

Command	Function
flowcontrol	Syntax:
This command enables flow	[no] flowcontrol
control.	Default Setting: Flow control enabled
Use the no form to disable	Command Mode: Interface Configuration (Ethernet, Port Channel)
flow control.	Command Usage: Flow control can eliminate frame loss by “blocking” traffic
	from end stations or segments connected directly to the switch when its buffers
	fill. When enabled, back pressure is used for half-duplex operation and IEEE
	802.3x for full-duplex operation.
	To force flow control on or off (with the flowcontrol or no flowcontrol command),
	use the no negotiation command to disable auto-negotiation on the selected
	interface.
	When using the negotiation command to enable auto-negotiation, the optimal
	settings will be determined by the capabilities command. To enable flow control
	under auto-negotiation, “flowcontrol” must be included in the capabilities list for
	any port
	Avoid using flow control on a port connected to a hub unless it is actually
	required to solve a problem. Otherwise back pressure jamming signals may
	degrade overall performance for the segment attached to the hub.
	Example: The following example enables flow control on port 5:
	Console(config)#interface ethernet 1/5
	Console(config-if)#flowcontrol
	Console(config-if)#no negotiation
	Console(config-if)#
shutdown	Syntax:
This command disables an	[no] shutdown
interface.	Default Setting: All interfaces are enabled.
To restart a disabled	Command Mode: Interface Configuration (Ethernet, Port Channel)
interface, use the no form.	Command Usage: This command allows you to disable a port due to abnormal
	behavior (e.g., excessive collisions), and then re-enable it after the problem has
	been resolved. You may also want to disable a port for security reasons.
	Example: The following example disables port 5:
	Console(config)#interface ethernet 1/5
	Console(config-if)#shutdown
	Console(config-if)#
switchport broadcast	Syntax:

broadcast storm control.
	(Range: 64-95232000)
Use the no form to disable
	Default Setting: Enabled for all ports
broadcast storm control.
	Packet-rate limit: 32000 octets per second
	Command Mode: Interface Configuration (Ethernet)
	Command Usage: When broadcast traffic exceeds the specified threshold,
	packets above that threshold are dropped.
	This command can enable or disable broadcast storm control for the selected
	interface. However, the specified threshold value applies to all ports on the
	switch.
	Example: The following shows how to configure broadcast storm control at 600
	packets per second:
	Console(config)#interface ethernet 1/5
	Console(config-if)#switchport broadcast octet-rate 600
	Console(config-if)#
