Hi Sprout,
The memory space of the device is limited. By default, only the logs of the warning or higher levels are recorded in the logbuffer. But the command operation log level is notifications, which will not be recorded in the logbuffer.
Log level:


If you just want to view recent operation records, run the display history-command command.
You can set the maximum size of the history command buffer to 256.
[HUAWEI] user-interface console 0
[HUAWEI-ui-console0] history-command max-size 256
If you want to record the command operation log in the logbuffer, there are two ways:
1. Reduce the level of logs recorded by the logbuffer:
[Huawei] info-center source default channel logbuffer log level notifications
2. Enable the logbuffer to record the SHELL module information.
