Which command is used to clear MCU alarms?

S series switches (excluding the S1700) in versions earlier than V200R002 support HGMP, and ndp enable and undo ndp enable commands can be configured. Switches in V100R006C05, V200R002, and V200R003 do not support the HGMP function. That is, the ndp enable and undo ndp enable commands are not supported. Switches in V200R005 and later versions can be configured with the ndp enable and undo ndp enable commands. The commands are used in the EasyDeploy function and are mandatory for enabling the network topology collection function.

For S series switches (except S1700 switches), run the following command to clear the recycle bin:
<HUAWEI> reset recycle-bin
Note: The delete XXX command in the user view only moves files to the recycle bin, but does not release the storage space. You can run the dir/all command to view information about all files, including deleted files in the recycle bin marked in brackets ([ ]). These files can be restored using the undelete command. To permanently delete these files from the recycle bin, run the reset recycle-bin command. The files that are deleted using the delete command without the /unreserved parameter are saved in the recycle bin.

Serial numbers of S series switches fall into two categories: - Equipment serial number (ESN): indicates the serial number of a switch. The ESN of a modular switch is also called the chassis serial number. - Serial number (SN) of each component: indicates the serial number of a card, subcard, optical module, power supply, or fan module. Select one of the following methods to obtain the ESN or SN of a switch or component: Method 1: View SN labels. Equipment or chassis SN: View the SN label attached to the device panel. (There is a slight difference between label locations on different models. For example, the label can locate on the front, rear, or top of the chassis.) Card serial number: View the SN label on the panel (upper-right or upper-left corner) or PCB (remove and check the card). Method 2: Run a command. Run the display elabel command to view the electronic label of each component. The BarCode field indicates the serial number. Method 3: Through the web system. When the web system is enabled on a device, view the chassis serial number through the web system. EasyOperation web system (supported only in V200R005 and later versions) Log in to a device through the web system and click Monitor on the toolbar to enter the Monitor page. You can view device information, including the chassis serial number. Web system classical version Log in to a device through the web system and click Device Summary on the toolbar to view device information, including the chassis serial number.

You can use commands to view the electronic labels. To view the part number and production date, run the display elabel command.
