Operate/release protection switching on FFP Tunnel Protection Group

Procedure 9-8.2: Operate/release protection switching on FFP Tunnel Protection Group

Overview

Use this procedure and the Web GUI or opr-protnswtmpls/rls-protnswtmpls TL1 command to operate/release protection switching.

The OPR-PROTNSW-TMPLS command is used to initiate protection commands for provisioned facility protection groups. The command can be used for the following FFP types: 1:1 (T) MPLS Protection and Dual Home revertive bidirectional (T)MPLS. User requests initiated with this command remain active until released with the RLS-PROTNSW-TMPLS command or overridden by a higher priority protection switch request (for example., Lockout or a SF condition on the working or protection tunnel, or a forced switch request on the working or protection tunnel). Assignment of protection resources is made in response to automatic or user initiated requests. Table 9-2, Protection switching request priorities shows the hierarchy or priority levels for requests in descending order.

Table 9-2: Protection switching request priorities

Priority	Request type
1 (highest)	Lockout of Protection
2	Signal Fail for Protection (SF-P)
3	Forced Switch for Working (FS)
4	Signal Fail for Working (SF)
5	Manual Switch to Working/Manual Switch to Protection
6	Wait to Restore
7 (lowest)	No Request

Step


1	Login to the VLNC42B.
2	From the Navigation menu, select TMPLS → Protection → FFP Switching. Equivalent TL1 command: `opr-protnswtmpls`/`rlsprotnswtmpls`. Result: The Fast Facility Protection Group Switching screen displays.
3	In the FFP AID drop-down box, select the FFP Tunnel Protection Group AID. The screen displays current values. See Fast Facility Protection Group Switching parameters.
4	In the Switch Command drop-down box, select the type of switch being performed. If required and the Switch Command is MAN, select the destination in the Destination drop-down box.
5	Click Submit to execute the command. End of steps

Fast Facility Protection Group Switching parameters

Parameter	Value	TL1 command
FFP AID	Access identifier of the FFP to retrieve.	rtrv-ffp-tmpls
Layer	Indicates if the protection is done at TUNNEL or PW layer. Valid value: TUNNEL. This is a display-only field.
Protection Type (ptype)	Specifies the type of the protection. Valid value: APSBIDIR (1:1 Bidirectional Linear APS) or DHOME (Dual Homing 1:1). This is a display-only field.
Working Tunnel	The working tunnel AID. This is a display-only field.
Protecting Tunnel	The protecting tunnel AID. This is a display-only field.
Active	Current switch position. This is a display-only field. Valid values: WKG or PROTN
Current Request (curreq)	This parameter specifies the state of APS executed for a FFP. This is a display-only field. Valid values: FRCD — A Forced switch requested at local node has been completed. FRCD-FE — A Forced switch requested at far-end node has been completed. LOCKOUT — The protection facility has been locked out requested at local node. LOCKOUT-FE — The protection facility has been locked out at far-end node. MAN — A Manual switch to working/protecting requested at local node has been completed. MAN-FE — A Manual switch to working/protecting requested at far-end node has been completed. NR — No switch request. SF — A switch has occurred due to a signal fail condition detected at local node. SF-P — A switch has occurred due to a signal fail condition for protection detected at local node. SF-FE — A switch has occurred due to a signal fail condition detected at far-end node. SF-P-FE — A switch has occurred due to a signal fail condition for protection detected at far-end node. WTR — Wait to Restore. The defect causing a switch to protection has cleared at local node. WTR-FE — Wait to Restore. The defect causing a switch to protection has cleared at far-end.
Pending Request (pendreq)	This parameter specifies the pending APS command which will be executed if the current request clears. This is a display-only field. Valid values: AUTOSWITCH, NR.
Hold Off Time (msec) (hldffptim)	Hold Off Time for automatic protection switching. This is a display-only field. Integers 0 - 10000 in step of 100 msec.
Revert Time (min) (rvrttim)	The parameter specifies the revert time in minutes. This is a display-only field. Valid values: integers in the range of 0 - 12 and 3060.
APS PHB (apsphb)	PHB Scheduling Class (PSC) associated to APS packets or the R-APS message for the Dual Homing protection type. This is a display-only field. Valid values: EF (default) HIGH2 AF1 AF2 AF3 AF4 DE LOW2
Switch Command (swtchcmd)	Switch Command to be performed. Valid values: FRCD, LOCKOUT, MAN, CLEAR.	opr-protnsw-tmpls/rls-protnsw-tmpls
Destination	Destination of the switch action addressed by the command and only applicable if the switch command is MAN. Values: WKG — Execute the requested switch action so that service ends up on the working section of the protection group. PROTN — Execute the requested switch action so that service ends up on the protection section of the protection group.	opr-protnsw-tmpls: destination
