Board-Level Protection

Board-level protection enables redundant protection switching at the board level. When board-level protection is configured, the board-level active/standby switching is triggered when a fault on the working link, port, or board is detected. In this user interface, you can configure board-level protection, including setting the protection switching pair, setting switching conditions, and performing protection switching operations.

Navigation Path

In the NE Explorer, click the NE and select Configuration > Board-Level Protection from the Function Tree.

Note

For the protection switching command, the Web LCT considers only whether a command is successfully issued, but not the result of executing the command. Therefore, after the Web LCT issues a switching command, you need to manually query the switching status of the equipment.

When creating the board-level protection, adhere to the following principles:

When you create the board-level protection, the available number of ports and type of ports of the working board must be the same as those of the protection board.
The protection board must not bear services.
When the TBE board accesses GE and FE electrical signals, the board-level protection is not supported.

Shortcut Menu Items

Item	Description
Forced Switching to Working	Forces the service to switch to the working board. This switching is performed regardless of the working board state, unless the working board is satisfying a higher priority bridging request.
Forced Switching to Protection	Forces the service to switch to the protection board. This switching is performed regardless of the protection board state, unless the protection board is satisfying a higher priority bridging request.
Clear Switching	Clears the current switching status.

Parameters

Field	Value	Description
Protection Group ID	1 to 65535	Displays the protection group ID.
Working Board	For example: 13-TBE	Displays the working board specified during protection group creation.
Protection Board	For example: 14-TBE	Displays the protection board specified during protection group creation.
Active Board	Working Board, Protection Board	Displays the current active board.
Working Board Availability	Usable, Unusable	Displays the status of the working board.
Protection Board Availability	Usable, Unusable	Displays the status of the protection board.
Switching Status	Forced Switch Request, Auto Switching, Idle, Unknown Default: Auto Switching	The Switching Status (BPS) parameter shows the status of BPS switching.
Extended Control Unit	Not Extended, SCS Extension	When one working service and one protection service are accessed to the working and protection boards respectively, the Extended Control Unit is Not Extended. When one service is accessed, the SCS board needs to duplicate the service and access the two services to the working and protection boards respectively. In this case, the Extended Control Unit is SCS Extension.
