Port link configuration

Use these commands to set port parameters for the port link.

Link commands are described in the following table. Using these commands, you can set port parameters such as speed, duplex, flow control, and negotiation mode for the port link.

The following table describes the Gigabit Link Configuration commands.

Table 77 Gigabit Link Configuration commands

Command	Description
speed {101001000auto}	Sets the link speed. Not all options are valid on all ports. The choices include:
	•	10 Mb/s
	•	100 Mb/s
	•	1000 Mb/s
	• “auto,” for automatic detection (default)
	Note: Ports 1-18 are set to 1000 Mb/s, and cannot be changed.
	Command mode: Interface port
duplex {fullhalfany}	Sets the operating mode. Not all options are valid on all ports. The choices
	include:
	•	Full-duplex
	•	Half-duplex
	• “Any,” for automatic detection (default)

Note: Ports 1-18 are set to full duplex, and cannot be changed.

Command mode: Interface port

flowcontrol {receivesendboth}

Sets the flow control. The choices include:

•Receive (rx) flow control

•Transmit (tx) flow control

•Both receive and transmit flow control (default) Command mode: Interface port

no flowcontrol	Sets the flow control to none.
	Command mode: Interface port
[no] auto	Enables or disables auto-negotiation for the port.
	Command mode: Interface port
show interface	Displays current port parameters.

Layer 2 configuration

The following table describes the Layer 2 Configuration commands. The following sections provide more detailed information and commands.

Table 78 L2 Configuration commands

Command	Description
vlan {<1-4095>}	Enter VLAN configuration mode.
	Command mode: Global configuration

[no] spanning-tree uplinkfast

Enables or disables Fast Uplink Convergence, which provides rapid Spanning Tree convergence to an upstream switch during failover.

Note: When enabled, this feature increases bridge priorities to 65500 for all STGs and path cost by 3000 for all external STP ports.

Command mode: Global configuration

spanning-tree uplinkfast	Configures the station update rate, in packets per second.
max-update-rate <10-200>	The range is 10-200. The default value is 40.
	Command mode: Global configuration
show layer2	Displays current Layer 2 parameters.
	Command mode: All
