2.2.3 Enable/disable specified interface

After system booting, all the interfaces are defaulted to be enable, and each interface can be

configured according to real situation.

Use following commands to enable/disable an Ethernet port.

shutdown

no shutdown

Shutdown means disable a port, while no shutdown means enable a port.

For example:

!Enable Ethernet interface 1

QTECH(config-if-ethernet-0/1)#no shutdown

!Disable Ethernet interface 25

QTECH(config-if-ethernet-1/1)#shutdown

When interface is shutdown, the physical link is working for diagnosis.

2.2.4 Configure port-control mode

After booting, by default, all ports are slave mode. Configure mode of each port.

Configure master/slave mode in interface configuration mode:

port-control mode { master | slave }

no port-control mode

no port-control mode is used to restore port to slave mode.

Example:

!Configure e1/1 to be master

QTECH(config-if-ethernet-1/1)# port-control mode master

!Restore port control mode of e1/1(default mode is slave)

QTECH(config-if-ethernet-1/1)# no port-control mode

Caution: Only extended GE TX can configure port control mode to work the configuration of

two GE TX with mode being force.

Show port-control mode inany configuration mode(only GE TX needs showing):

show port-control mode

2.2.5 Configure interface duplex mode and speed rate

10/100/1000Base-T supports 10Mbps, 100Mbps, 1000Mbps and full duplex, half duplex auto-

negotiation. 1000Base-X only supports 1000Mbps, full duplex and auto-negotiation. By default,

the port is in auto mode. User can configure the working mode by himself. Use speed

command to configure the speed and duplex command to configure duplex.
