Usage Guidelines

Usage Scenario

If a problem occurs, you can query log information to learn about what happened during device operation. This is helpful for fault location. The file name is generated automatically and the log format is log.log.

If the size of the existing information file reaches the upper limit, the system transfers the information file into a historical compress file with the name of "log_SlotID_time.log.zip". The "slot ID" indicates the slot where the log is generated, and "time" indicate the date and time when the log was recorded.

Example

The actual command output varies according to the device. The command output here is only an example.

# Display the information file of the log.log format in the specified directory.
