Procedure 9-6.1: Create Tunnel segments and terminated Tunnel AIDs

- Overview

Use this procedure to create Tunnel segments and point-to-point bidirectional terminated PSN Tunnels. The System supports a maximum of 750 bidirectional MPLS TUSegments, of which up to 250 may be terminated Tunnels.

Use the Web GUI or the ent-tmpls-tuseg command to create a TUSegment.

Successful completion of this command automatically generates a TUNNEL AID output only if TYPE=TERMINATION. In the case of TYPE=SWAP, this command creates the TUSegments to be used in cross-connection in intermediate nodes.

When a TUSEG is created, the system assigns a TUSEG AID which uniquely defines the LSP Tunnel; this AID is obtained by the combination of Shelf and TUSEG index. For example, TUSegment AID = TUSEG-1-1{1-750}.

If TUSEG is (type = terminated), the system automatically creates a Tunnel AID, by: Shelf, Tunnel ID, Tunnel instance (In manual, fixed to 1), Ingress LER address (In manual configuration always 0.0.0.0), Egress LER address (In manual configuration always 0.0.0.0). For example: TUNNEL AID = TUNNEL-1-1-{1-500}-1-0-0-0-0-0-0-0-0

The TUNNEL parameters can be modified using the ed-tmpls-tunnel command. This TUSegment is automatically deleted when the TUNNEL is deleted using the dlt-tmpls-tunnel command.

Step
 
1

Login to the VLNC42B.


2

From the Navigation menu, select TMPLS → Tunnel Management → Create Terminated Tunnel.

Equivalent TLI command: ent-tmpls-tuseg.

Result:

The Create Terminated Tunnel Segment screen displays.


3

Enter the parameters as required, then click Submit. See Tunnel segment input parameters.

Equivalent TLI command: ENT-TMPLSTUSEG:[ TID]::[CTAG]::PORT,[TYPE],[DIR],[USERNAME]:[L2ENCAPPROFAID=][, INLABEL=][,OUTLABEL=][,PHBPROF-AID=][,OAMPHB-AID=][,MEP=][,MEGID=][, MEP-ID=][,EXPMEPID=][,CVRX=][,CVTX=][,CVPERIOD=][,CVPHB=][,ALMPROF=][,PS-DDM-SD=];.

Result:

Output:

  • TUSegment AID. This output parameter is used to refer to the TUSegment entity in ED-TMPLS-TUSEG, RTRV-TMPLS-TUSEG and DLT-TMPLS-TUSEG commands.

  • Tunnel AID, identifies the TUNNEL automatically generated for Terminated TUSegment.

Example:

ENT-TMPLS-TUSEG:::TS001::MPLSIF-1-1-1-1,TERMINATION,BID [TS001] (1).

User Name

The user name for the TUSegment. The valid value is a character string containing up to 30 valid characters.

ent-tmpls-tuseg: username

In Label (inlabel)

The expected Label for incoming segment associated to Sink TUSegment. The label value must be unique in the system. Valid values: an integer in the range of 16 - 1023. Note that the In Labels 16 - 1023 are for services and 130048 - 131071 are for IEEE 1588 PTP traffic.

ent-tmpls-tuseg: inlabel

Out Label (outlabel)

The Transmitted Label for outgoing segment to Source TUSegment. The label value must be unique on the MPLS port basis; the Out Label shall not exist for the MPLSIF referenced by Port parameter. Valid values: an integer in the range of 16 - 1048575.

ent-tmpls-tuseg: outlabel

PHB Profile (phbprof-aid)

Per-Hop Behavior Profile. This is a drop-down list containing all PHB Profile in the system. The default value is PHBPROF-n, where n is the value selected in the PHB Range field of the Global Network configuration screen. The default is PHBPROF-2.

ent-tmpls-tuseg: phbprof-aid

L2 Encapsulation Profile (l2encapprof-aid)

L2 encapsulation profile AID to be used in case of mapping of MPLS over Ethernet when a switched network is present. The System will check if profile is present using this parameter as access-key.

Default: L2ENCAPPROF-1.

ent-tmpls-tuseg: l2encapprof-aid=

Diagnostic Monitoring SD Prot. Switch (PS-DDM-SD)

Enables/disables the Protection Switch feature for Signal Degrade detected on the basis of the optical power monitored by Digital Diagnostic Monitoring (DDM) capable SSF/ TSF.

ent-tmpls-tuseg: ps-ddm-sd

Alarm Profile (almprof)

The Alarm Severity Assignment Profile (ASAP) name to use with this facility.

1-40 alphanumeric characters (plus '-') assigned as the userlabel for the desired profile.

ent-tmpls-tuseg: almprof=

MEP (mep)

Enables/disables MEP function for termination TUSegment. For a MEP sink point, it enables the capability to process the received Connectivity Verification (CV) packets and generate the corresponding alarms.
