Parameters

Following is the description of the parameters of ODUk SNCP protection.

Table 1 lists the parameters involved in the configuration of ODUk SNCP protection.

Table 2 lists the parameters involved in query and modification of ODUk SNCP protection status.

**Table 1** Create SNCP
Field	Value	Description
Protection Type	SW SNCP, ODUk SNCP	Specifies the level of the new service.
SNCP Type	For SW SNCP For ODUk SNCP: SNC/I, SNC/N, SNC/S	Displays the protection type of the service. The SNC/I protection is for inherent monitoring, and the trigger condition for protection switching is the overhead alarm in SM section. As a result, the scenario that the electrical regenerator is passed through is not supported (in this scenario the overhead in SM section is terminated). The SNC/S protection is for sublayer monitoring, and the trigger condition for protection switching is the overhead alarms in SM and TCM sections. The TCM management should be configured to the source and sink stations of the SNC/S protection. The SNC/N protection is for non-intrusive monitoring, and the trigger condition for protection switching is the overhead alarms in SM and TCM/PM sections. The SNC/N protection can be applied to most scenarios.
Service Type	For SW SNCP: GE, 10GE, FE, OTU1, OTU2, OTU3, OTU5G, STS3, STS12, STS48, STS192, STS768, FC100, FC200, FC400, FC1200, FICON, FICON Express, HDTV, DVB-ASI, DVB-SDI, ESCON, FDDI For ODUk SNCP: ODU0, ODU1, ODU2, ODU3	Specifies the service type of the new service.
OTN Level	Corresponding to ODUk SNCP: SNC/I: Null SNC/N: PM, TCM1-TCM6 SNC/S: TCM1-TCM6	Displays the monitoring layer of SNCP.
Revertive Mode	Revertive, Non-Revertive Default: Non-Revertive	Chooses whether the service is switched to the original working path after the failure is eliminated. If you want the service to be switched back to the original working path then, select Revertive. If you do not want the service to be switched back then, select Non-Revertive. The default value is recommended.
WTR Time (s)	300-720 Default: 300	Sets the wait-to-restore time. It is the time interval between the time when the working service is detected to be normal after switching and the time when the service is switched back to the working path. You can modify the WTR Time (s) only when the value of Revertive Mode is Revertive. The default value is recommended.
Working Channel Hold-Off Time (100ms)/Protection Channel Hold-Off Time (100 ms)	0-100 Default: 0	Sets the time interval between the time when the system detects signal degrade and the time when the service switching occurs, in order to avoid repeated switching when the service status is not stable. The switching delay time is in 100 milliseconds. For example, if you enter 5, the delay time is 500 milliseconds. Sets the delay time. To avoid the repeated switching when the service status is not stable, generally the delay time needs to be set. Especially in the network of multi-protection cascading, to avoid that the switching occurs to downstream protections at the same time, the delay time needs to be set for downstream protections. The hold-off time of the working and protection channels can be set respectively.
SD Switching	Enabled, Disabled Default: Disabled	Sets whether SD can trigger the protection switch.
Direction	Unidirectional, Bidirectional Default: Unidirectional	Sets whether the service is bidirectional or unidirectional.
Remarks	For example: ODUkSNCP-SRV1	Indicates the protection group memo information. It is a string with a maximum length of 64 characters.
Source Slot	Slot-Board Name	Displays the source slot of the cross-connection.
Source Optical Port	Port No. (Port name)	Displays the source port of the cross-connection.
Source Optical Channel	Optical path No.	Displays the source path of the cross-connection.
Sink Slot	Slot-Board Name	Displays the sink slot of the cross-connection.
Sink Optical Port	Port No. (Port name)	Displays the sink port of the cross-connection.
Sink Optical Channel	Slot-Optical port No.-Optical path No.	Displays the sink path of the cross-connection.
ODUflex Timeslots	3 to 7	Indicates the quantity of ODUflex timeslots. NOTE: Set this parameter when Level of a WDM cross-connection is ODUflex. The quantity of ODUflex timeslots ranges from 3 to 7, and the rate that ODUflex supports is 3.75 Gbit/s (3 x 1.25 Gbit/s) to 8.75 Gbit/s (7 x 1.25 Gbit/s).

**Table 2** SNCP Service Parameters
Field	Value	Description
Source Channel	Source Channel Number-Source Slot Number-Source Port Number-Source Optical Channel Number	Displays the source timeslot of the service.
Service Sink	Sink Channel Number-Sink Slot Number-Sink Port Number-Sink Optical Channel Number	Displays the sink timeslot of the service.
Protection Type	SW SNCP, SNC/I, SNC/N, SNC/S	Displays the type of a service.
Level	GE, Any, ODU1, ODU2	Displays the level of a service.
OTN Level	Corresponding to SW SNCP: Null Corresponding to ODUk SNCP: SNC/I: Null SNC/N: PM, TCM1-TCM6 SNC/S: TCM1-TCM6	Displays the monitoring layer of SNCP.
Revertive Mode	Revertive, Non-Revertive Default: Non-Revertive	Displays the revertive mode that indicates whether services are switched back from the protection channel after the working channel is normal. The default value is recommended.
WTR Time (s)	300-720 Default: 300	Sets the wait-to-restore time. It is the time interval between the time when the working service is detected to be normal after switching and the time when the service is switched back to the working path. You can modify the WTR Time (s) only when the value of Revertive Mode is Revertive. The default value is recommended.
Working Channel Hold-Off Time (100ms)	0-100 Default: 0	Sets the time interval between the time when the system detects signal degrade and the time when the service switching occurs, in order to avoid repeated switching when the service status is not stable. The switching delay time is expressed in 100 milliseconds. For example, if you enter 5, the delay time is 500 milliseconds. Sets the delay time. To avoid the repeated switching when the service status is not stable, generally the delay time needs to be set. Especially in the network of multi-protection cascading, to avoid that the switching occurs to downstream protections at the same time, the delay time needs to be set for downstream protections.
SD Switching	Enabled, Disabled	Sets whether SD can trigger the protection switch.
SD Trigger Condition	-	Display the SD trigger condition.
Current Status	Normal State WTR Status Manual (from Protection to Working) Switching State Manual (from Working to Protection) Switching State Forced (from Protection to Working) Switching State Forced (from Working to Protection) Switching State SD Switching SF Switching Lockout Unknown	Displays the switching status of the current protection group.
Current Channel	Working Channel, Protection Channel, Delay Start, Unknown	Displays whether the working service or the protection service is selectively received.
