Huawei switch
supports rich and flexible service features and thus improves the operability,
manageability, and service expansibility. The Huawei switches include Huawei
data center switches, campus switches (Huawei S9700, S7700, S6700, S5700,
S3700, S2700,
S9300, S6300, S5300, S3300, S2300 series) and SOHO&SMB switches (Huawei S1700
series), fully meeting enterprise and telecom customers'
requirements for flexible networking. Here we will tell you the method to collect
diagnostic information for Huawei switches.
The display diagnostic-information
command provides outputs of multiple commonly used display
commands. You can use this command to view diagnostic information about the
switch, including the startup configuration, current configuration, interface
information, time, and system version.
The display diagnostic-information [
file-name ] command displays the device diagnostic information on screen
or saves the information to a text file (.txt). The device diagnostic
information includes startup configuration, current configuration, interface
information, time, and system version. The following is an example:
<HUAWEI> display
diagnostic-information dia-info.txt
This
operation will take several minutes, please wait.........................
................................................................................
...
Info: The diagnostic information was saved
to the device successfully.
The default path of the text file is flash:/. You can run the dir command in
the user view to check whether the text file has been created.
When a fault occurs on the switch, provide the diagnostic information to
the Huawei agent or Huawei immediately for fast fault location.
If diagnostic information is displayed on the screen, you can press Ctrl+C
to stop the display any time.
This command is used to collect diagnostic information for fault location.
Executing this command may affect the system performance. For example, it may
cause a high CPU usage. Therefore, do not run this when the switch is running
normally. Do not run this command on multiple terminals connected to the switch
at the same time. Otherwise, the CPU usage of the switch will increase sharply,
causing system performance deterioration.
NOTE:
All the commonly used terminal configuration programs can save display
information to a file. For example, if you are using HyperTerminal on a Windows
operating system, choose Transfer > Capture Text, enter a file name, and
then click Start. After that, run the display diagnostic-information command. All the
diagnostic information is displayed on the terminal screen and automatically
saved in a file in the specified path.
