+7(495) 797-3311www.qtech.ru

Москва, Новозаводская ул., 18, стр. 1

Example:

! Enter interface group configuration mode which includes Ethernet 1 to 3

QTECH(config)#interface range ethernet 0/0/1 to e 0/0/3

2.2.4 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 1

QTECH(config-if-ethernet-0/1)#shutdown

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

2.2.5 Configure interface duplex mode and speed rate

100 BASE TX supports the speed of 10Mbps and 100Mbps, while 100 BASE FX supports the

speed of 100Mbps. 1000 BASE TX supports the speed of 10Mbps, 100Mbps and 1000Mbps,

while 1000 BASE FX supports the speed of 1000Mbps. 100 BASE TX and 1000 BASE TX

support the duplex mode of half, full duplex and auto-negotiation mode. 100 BASE FX and

1000 Base FX only support the duplex mode of full duplex. By default, 100 Base FX is in the

mode of 100M and full duplex, and other interfaces are auto-negotiation. User can configure

the working mode by himself. Use speed command to configure the speed and duplex

command to configure duplex.

 Command form in interface mode

speed { 10 | 10auto | 100 | 100 auto | 1000 | 1000 auto | auto }

no speed

duplex { auto | full | half }

no duplex

For example:

! Configure the speed of Ethernet 0/0/1 to 100Mbps and duplex mode to be full duplex

QTECH(config-if-ethernet-0/0/1)#speed 100

QTECH(config-if-ethernet-0/0/1)#duplex full

In system, one of the value of speed and duplex is configured to be auto,the other will be

auto.

2.2.6 Interface Prioruty Configuration

There are 8 priorities from 0 to 7, and the default interface priority is 0. The larger the priority

value is, the higher the priority is. And the packet with the higher priority will be quickly

handled. If there are too much packet to be handled in some interface or the packet is urgent

to be handled, priority of this interface can be configured to be high-priority.

Use following command in interface configuration mode:

 Configure priority of Ethernet 0/0/5 to be 1

QTECH(config-if-ethernet-0/0/5)#priority 1

Qtech QSW-3200-24T [23/136] Enable disable specified interface
