Create control plane network connections

Procedure 9-13.5: Create control plane network connections

Overview

Use this procedure to create an end-to-end soft permanent connection (SPC) between the speciﬁed TNA end points.

A soft permanent connection is a user-to-user connection in which the user-to-network portion of the end-to-end connection is established by the network management system as a permanent connection, and the network portion of the end-to-end connection is established as a switched connection using the control plane. See Figure 9-21, Soft permanent connection (SPC) in a control plane network.

An end-to-end connection connecting edge ports consists of E-NNI connection segment(s) and I-NNI connection segment(s). E-NNI signaling is responsible for establishing the E-NNI portion of the end-to-end connection, as well as providing additional information that conveys the end-to-end request to the border nodes in the core for establishing the I-NNI portion of the end-to-end connection. In the control plane, the end-to-end points of an SPC are identiﬁed by Source and Destination TNAs, Source and Destination Logical Port IDs, and Source and Destination Subnetwork Point (SNP) IDs (called Source Labels [timeslot tributaries]). See Table 9-5, ENT-CONN parameters.

Steps

Complete the following steps to create a control plane network connection. Refer to Table 1.


1	From the System View menu, select Configuration → Create Control Plane Network Connections.
2	Enter the Service Attributes for the control plane connection. Reference: Table 9-5, ENT-CONN parameters
3	Select the Source TNA Address Type from the Source End Point attributes, then click Select. Result: The Tributary selection screen displays.
4	Expand the TNA address being used for the connection, select (highlight) the logical port. Click on the tributary, then click Select at the bottom of the screen. Result: The Source End Point attributes (Source TNA Address, Source Logical Port, and Source Label) are filled in.
5	Enter the parameters for the Destination End Point attributes, then click Apply. Read the warning message, then click Yes to execute the command. Result: Within a few seconds, a completion message is received.
6	Read the completion message, click OK, then click Cancel to exit.
7	From the System View menu, select View → Control Plane Network Connections to verify the connection. End of steps

Control plane network connection parameters

Table 9-5, ENT-CONN parameters lists the provisionable parameters for a control plane network connection:

Table 9-5: ENT-CONN parameters

Parameter	Description
Service Parameters
callid	Call ID. Call Identifier is an operator-specific ﬁxed-length 12-byte (24-character) hexadecimal string. One suggested format is where the first 4 bytes (8 characters) represent the source network element address (the hexadecimal encoding of the nodeid [ent-node]) and the remaining 8 bytes (16 characters) represent the local identifier.
protype	Protection Type. Protection type specifies the protection type for the E-NNI segments of the SPC. Value: 0x1 — unprotected 1+1 — protected
servlevel	Service Level is an integer in the range 0–255 that speciﬁes the service level for the I-NNI segments of the SPC.
dir	Direction. Direction specifies whether the connection is unidirectional or bidirectional. Value: 1WAY — unidirectional 2WAY — bidirectional
bandwidth	Signal Rate speciﬁes the signal rate of the connection. Values: STS1 STS3c STS12c STS48c STS192c
Source End Point Parameters
srctnatype	Source TNA Address Type. Source Transport Network Assigned Address (TNA) Type. Values: IPv4 — An IPv4 formatted Source TNA address consisting of four dot-separated integers ranging from 0 to 255, for example, 220.10.10.10. IPv6 — An IPv6 formatted Source TNA address consisting of 8 dash-separated 4-digit hexadecimal numbers. For example, fedc-0000-0000-76b4-417a-1080-3210-1111. NSAP — An NSAP formatted Source TNA address consisting of a 40-digit hexadecimal string. For example, 39840f8000000000000000000008006a067197aa.
srctnaaddress	Source TNA Address. Identifies an address assigned to one endpoint of the connection by the transport service provider. Srctnaaddress, in conjunction with srclogportid and srclabel, identifies the source of the connection. See srctnatype for the allowable srctnaaddress values as a function of the srctnatype value.
srclogportid	Source Logical Port ID. An integer that identifies the source EDGE port (within the TNA). In conjunction with srctnaaddress and srclabel, it identifies the source of the connection. Value is an integer in the range from 1 to 4294967295.
srclabel	Source Label. Source Label specifies a timeslot (tributary) on the source EDGE port identified by srclogportid. In conjunction with srctnaaddress and srclogportid, it identifies the source of the connection. Source Label has a format of S-U-K-L-M, where: S speciﬁes a particular STS-3 group within an STS-N, U speciﬁes a particular STS-1 within an STS-3 group. K, L, and M are each 0. Values: S 0 (port/line with a rate of STS1 or less) 1 (1st STS-3c within an STS-N) 2 (2st STS-3c within an STS-N) ... N/3 (N/3th STS-3c within an OC-N port) U 0 (on port/line with a rate of STS1 or less, and when Signal Rate (bandwidth)=STS3c or greater) 1 (1st STS-1 within an STS-3) 2 (2nd STS-1 within an STS-3) 3 (3rd STS-1 within an STS-3) K=0 L=0 M=0 For example, for connecting the fourth STS-1 in an OC-48 EDGE port, srclabel=2-1-0-0-0. For a connection to a VCG EDGE port, divide the VCG tributaries into groups of 3 (1–3, 4–6, 7–9,...) and apply the rules for OC-n ports.
Destination End Point Parameters
desttnatype	Destination TNA Address Type.. Destination Transport Network Assigned Address (TNA) Type. See srctnatype for the format description.
desttnaaddress	Destination TNA Address. Destination Transport Network Assigned Address (TNA) identifies an address assigned to one endpoint of the connection by the transport service provider. desttnaaddress, in conjunction with destlogportid and destlabel, identifies the destination of the connection. See desttnatype for the allowable values as a function of the desttnatype value.
destlogportid	Destination Logical Port ID. Destination Logical Port ID is an integer that identifies the destination EDGE port (within the TNA). In conjunction with desttnaaddress and destlabel, it identifies the source of the connection. Value is an integer in the range from 1 to 4294967295.
destlabel	Destination Label. Destination Label specifies a timeslot (tributary) on the destination EDGE port identified by destlogportid. In conjunction with desttnaaddress and destlogportid, it identifies the destination of the connection. See srclabel for the format description.
