Utilizing the Command Line Interface
2-22 Managing the XSR
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.
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
Note: All interfaces are disabled by default.
