1.1 Display Commands
This section describes the functions of display commands and lists the display commands in
common use.
As an important means to maintain and troubleshoot a network, the display commands can be
used to collect current information about the version, device, and diagnosis of the S9300.
Table 1-1 lists the display commands in common use. For details, refer to the Quidway
S9300 Terabit Routing Switch - Command Reference.
CAUTION
You are disallowed to run the display diagnostic-information command simultaneously on
multiple terminals connected to the S9300. Otherwise, the CPU usage of the S9300 may
obviously rise and the network performance may be degraded.
Table 1-1 Common display commands
Command Description
display current-configuration Displays the parameters that take effect currently on the
S9300.
display device Displays information about the S9300.
display version Displays the version and boards information of the
S9300.
display this Displays valid configurations in the current view.
display diagnostic-information It is mainly used to collect information about the S9300
when a fault cannot be located or rectified. Then, you can
send the information to Huawei technical personnel for
fault analysis.
NOTE
This command is not recommended for routine troubleshooting.
display this interface Displays the current status of the interface.
1.2 Displaying the Status of the S9300
This chapter describes how to use display commands to view the version, CPU, memory, and
voltage of a device.
1.2.1 Displaying Information About the S9300
You can use the display command to view information about S9300 components.
