Enterasys Networks X-PeditionTM manual Enabling an Interface, Disabling an Interface

Utilizing the Command Line Interface

Ports can be enabled or disabled, configured for default settings, associated tables, clock rate, priority group, and encapsulation, for example. Refer to the XSR CLI Reference Guide for more details on Interface mode commands.

Note: All interfaces are disabled by default.

Enabling an Interface

The following command enables an interface.

XSR(config-if<S2/0>)#no shutdown + Enables serial interface 2

Disabling an Interface

An interface can be administratively disabled with the shutdown command:

XSR(config-if<S2/0>)#shutdown + Disables interface

Configuring an Interface

You can configure an interface only after invoking Interface configuration mode. Each interface can be configured with a set of interface-specific commands. If you are unsure which commands are available, type ? to list them for the particular port. Consider the following sequence of commands to configure a GigabitEthernet interface:

XSR#config terminal

XSR(config)#interface gigabitethernet 2

XSR(config-if<G2>)#?

description + Text describing this interface duplex + Manually set the duplex mode exit + Quit interface configuration mode help + Description of the interactive help system ip + Interface Internet Protocol config commands loopback + Configure interface for internal loopback no + Negate a command or set its defaults shutdown + Shutdown the selected interface speed + Manually set the line speed XSR(config-if<F1>)exit+ Quit Interface mode

Displaying Interface Attributes

You can display the current settings of an interface when in Privileged EXEC or Global configuration mode. For example, type:

XSR#show interface fastethernet 1

or:

XSR(config)#show interface serial 1/0
