| Parameter | Description | Value |
|---|---|---|
file-name |
Specifies the log file name, which can contain the drive and path. |
The value is a string of case-insensitive characters, spaces not supported. If the parameter value does not contain any path, it is a string of 1 to 64 bytes. Otherwise, it is a string of 1 to 160 bytes. |
offset |
Displays the log file with the specified offset or byte. |
The value is an integer that ranges from 0 to 2147483647. |

When encountering problems, you can query log information to know about what happened during device operation. This is helpful for fault location.
The file name is generated automatically by the system. The file name extension of the log file is *.log or *.dblg. When the current log file size reaches the specified upper limit, the system compresses the file into a *.log.zip or *.dblg.zip file.
You can view the *.log files or *.log.zip files. When viewing a *.log.zip file, you can press Ctrl+C to abort command execution.
When viewing the *.log.zip file, it is recommended that the length of the file name (including the driver and path) not exceed 62 bytes. Otherwise, the content of the file may fail to be viewed.
If the files you filter based on the pipe character are large and no qualified log file is displayed, the command fails to display any output for a long period of time until the command execution finishes.
For details about the log format, see "Log Message Format Description" in the S2720, S5700, and S6700 V200R019C10 Log Reference - Introduction.
