Port Protection

In this user interface, you can create, configure and modify the port protection group. Port protection is used to switch the service to the protection port when the working port becomes faulty. It ensures service availability. A working port and the corresponding protection port are regarded as a port protection group.

Navigation Path

In the NE Explorer, select an NE and choose Configuration > Port Protection from the Function Tree.

Note

For the protection switching command, the U2000 Web LCT considers only whether a command is successfully issued, but not the result of executing the command. Therefore, after the U2000 Web LCT issues a switching command, you need to manually query the switching status of the equipment.

Parameters

**Table 1** Protection Group Parameters
Field	Value	Description
Protection Group Name	For example: NE122-69-1	Displays the protection group name.
Protection Type	Optical Line Protection, Intra-Board 1+1 Protection, Client 1+1 Protection	Displays the protection type of the protection group.
Revertive Mode	Revertive, Non-Revertive	Indicates whether the service is automatically switched from the standby channel to the active channel after the active channel becomes normal. Revertive means that the service can be automatically switched. Non-Revertive means that the service is not switched to the active channel after the active channel becomes normal.
WTR Time (mm:ss)	5:00 to 12:00	WTR time indicates the time interval between the time when the active channel becomes normal and the time when the service is switched from the standby channel to the active one. The Revertive Mode is valid only when the value is Revertive.
SD Switching	Enabled, Disabled	Displays the SD trigger flag. NOTE: The optical line protection only supports the value Disabled.
Switching Status	Idle, Switching, Unknown	Displays the current switching status of the protection group. NOTE: Unknown: Click Query, the current Switching Status, Working Channel Status and Protection Channel Status will be displayed.
Remarks	The maximum length is 64 characters.	Enters extra notes of the NE if desired. NOTE: The following characters are not permitted: =, :, ,, ;, ", \, ?.
NE with Control Channel/Monitoring Channel	For example: NE93	Sets the NE with the control channel.
Board with Control Channel/Monitoring Channel	Equipment that supports the master and slave shelf management: shelf ID(shelf name)-slot number-board name Equipment that does not support the master and slave shelf management: slot number-board name	Sets the board with the control channel.
Group State	IS, OOS	Displays the state of the protection group. Clicks State to modify the state of the protection group. IS: In Service OSS: Out of Service
Switching Mode	Unidirectional Switching, Bidirectional Switching	Sets and displays the switchover mode of the protection group. NOTE: The parameter only applies to Intra-Board 1+1 Protection. If Control/Detection Channel is NULL, this parameter is unavailable.

**Table 2** Channel Status Parameters
Field	Value	Description
Protection Group Name	For example: NE122-69-1	Displays the protection group name.
Current Channel	Work, Protect, Unknown	Displays the path of the current service.
Working Channel	Equipment that supports the master and slave shelf management: NE name-shelf ID(shelf name)-slot number-board name-port number(port name) Equipment that does not support the master and slave shelf management: NE name-slot number-board name-port number(port name)	Displays the working channel of the protection group.
Working Channel Status	Idle, SF Switched, SD Switched, Locked, Force Switching, Manual Switching, WTR, DNR, Unknown	Displays the status of the working channel.
Working Channel Hold-Off Time (100ms)	0 to 100	Displays the delay time of the switch from the working channel to the protection channel. Delay time is the time delayed for the protection group to switch from the current channel to another channel. It effectively avoids repeated switching when the service status is not stable.
NE with Control Channel/Monitoring Channel	For example: NE93	Sets the NE with the control channel.
Board with Control Channel/Monitoring Channel	Equipment that supports the master and slave shelf management: shelf ID(shelf name)-slot number-board name Equipment that does not support the master and slave shelf management: slot number-board name	Sets the board with the control channel.
Control Channel/Detection Channel	Equipment that supports the master and slave shelf management: NE name-shelf ID(shelf name)-slot number-board name-port number(port name) Equipment that does not support the master and slave shelf management: NE name-slot number-board name-port number(port name)	Displays the protected channel information of the control board.
NE with Protection Channel	For example: NE93	Sets the NE with the protection channel.
Board with Protection Channel	Equipment that supports the master and slave shelf management: shelf ID(shelf name)-slot number-board name Equipment that does not support the master and slave shelf management: slot number-board name	Sets the board with the protection channel.
Protection Channel	Equipment that supports the master and slave shelf management: NE name-shelf ID(shelf name)-slot number-board name-port number(port name) Equipment that does not support the master and slave shelf management: NE name-slot number-board name-port number(port name)	Displays the protection channel of the protection group.
Protection Channel Status	Idle, Locked, SF Switched, SD Switched, Force Switching, Manual Switching, Unknown	Displays the status of the protection channel.
