Debug
Cisco IOS provides two commands to provide information on your interfaces: show interface GigabitEthernet 0/X (where X is
either 0 or 1) and show controllers GigabitEthernet 0/X (where X is either 0 or 1).
The output of the show interface command is useful for determining the current operating mode of the interface
(speed/duplex/media-type) and the current interface statistics.
The output of the show controller command displays more information specific to the Cisco 7304 router Gigabit Ethernet
interface. For example, it shows the detected link status, speed, and duplex, and also determines the current status of
autonegotiation and the link partners' abilities (if it is an autonegotiation-capable interface). (Speed and duplex are always full
duplex, 1000-Mbps.)
The show controller command also displays the current operating state of the driver and the Ethernet controller hardware. The
show controller command is a very powerful debugging aid, especially for Cisco engineers should you need help in debugging
a problem. If you have any problems with your Gigabit Ethernet interfaces, you will need to provide this information to Cisco
for analysis.
Reset the Interface
Should you have a problem with your interface and wish to try and reset it, use the command:
clear interface GigabitEthernet 0/X (where X is either 0 or 1)
Clear Counters
Interface counters may be cleared (reset) by using the command:
clear counters GigabitEthernet 0/X (where X is either 0 or 1)
Using this command will not reset the interface.

Save the Running Configuration to NVRAM

To store the configuration or changes to your startup configuration in NVRAM, enter the copy running-config startup-config
command at the prompt:
Router#
Router# copy running-config startup-config
Using this command saves the configuration settings that you created in the router using configuration mode and the setup
facility. If you fail to do this, your configuration will be lost the next time you reload the router.

Check the Running Configuration Settings

To check the value of the settings you have entered, enter the show running-config command at the prompt:
Router#
Router# show running-config
To review changes you make to the configuration, use the EXEC mode show startup-config command to display the information
stored in NVRAM.

View Your System Configuration

You can use the show version (or show hardware) and the show c7300 commands to display the system hardware, the software
version, the names and sources of configuration files, and the boot images. Use the show c7300 command to determine what
type of line card is installed.
For specific information on the show version, show c7300, and other commands, refer to the modular configuration and
modular command reference publications in the Cisco IOS software configuration documentation set that corresponds to the
software release installed on your Cisco hardware.
