Parameters
hardware: Specifies hardware-related operating information.
infrastructure: Specifies operating information for the fundamental features.
l2: Specifies operating information for the Layer 2 features.
l3: Specifies operating information for the Layer 3 features.
service: Specifies operating information for Layer 4 and upper-layer features.
key-info: Displays or saves only critical operating information. The device might have a large
amount of operating information if an exception occurs or after the device runs a long period of time.
Specifying this keyword reduces the command execution time and helps you focus on critical
operating information. If you do not specify this keyword, the command displays or saves both critical
and non-critical operating information.
filename: Saves the information to a file. The filename argument must use the .tar.gz suffix. If you do
not specify this argument, the command prompts you to choose whether to save the information to a
file or display the information.
Usage guidelines
You can use one of the following methods to collect operating statistics for diagnostics and
troubleshooting:
•
Use separate display commands to collect operating information feature by feature or module
by module.
•
Use the display diagnostic-information command to collect operating information for multiple
or all features and hardware modules.
To save storage space, this command automatically compresses information before saving
information to a file. To view the file content:
Use the tar extract command to extract the file.
1.
Use the gunzip command to decompress the extracted file.
2.
Use the more command to view the content of the decompressed file.
3.
If you do not specify any feature parameters, this command displays or saves the operating
information for all features and modules.
If you do not specify a file name for the command, the system prompts you to choose whether to
display or save the information. If you choose to save the information, the system automatically
assigns a file name and displays the file name in brackets. For file name uniqueness, the file name
includes the device name and the current system time. If the device name contains any of the
following special characters, the system uses an underscore (_) to replace each special character:
forward slashes (/), backward slashes (\), colons (:), question marks (?), less than signs (<), greater
