QTECH
Software Configuration Manual
4-50
For example :
! Enable Ethernet interface 1
QTECH(config-if-ethernet-0/0/1)#no shutdown
! Disable Ethernet interface 25
QTECH(config-if-ethernet-0/1/1)#shutdown
When interface is shutdown, the physical link is working for diagnosis.

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, which ofthe speed or duplex setup to auto , and the another will be setup to auto too.
4.2.5
Interface Priority 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
Restore the default priority of Ethernet 0/0/5
QTECH(config-if-ethernet-0/0/5)#no priority
4.2.6
Interface description configuration
Use following command to describe interface to distinguish each interface from others. Configure it in
interface configuration mode.
description
description-list
For example :
! Configure description string “red” for the Ethernet 0/0/3
QTECH(config-if-ethernet-0/0/3)#description qtech
! Display description of Ethernet 0/0/3
