Parameter Description: Parameters for Configuring ATM/IMA Services (in End-to-End Mode)

This section describes the parameters that are used for configuring ATM/IMA services in end-to-end mode.

Table 3-395  Parameters for configuring PWE3 services

Field

Valid Value

Description

Service Template

NOTE:

This parameter is optional and helps users quickly configure various services. If this parameter value is not specified, the subsequent service configuration is not affected.

DEFAULT_PWE3_CES_PTN, DEFAULT_PWE3_ETH_PTN, DEFAULT_PWE3_ATM_PTN

NOTE:
  • Only DEFAULT_PWE3_ATM_PTN is valid for ATM services.
  • The OptiX OSN equipment does not support the following service templates:
    • DEFAULT_PWE3_ATM_ROUTER
    • DEFAULT_PWE3_CES_ROUTER
    • DEFAULT_PWE3_ETH_ROUTER
    • DEFAULT_PWE3_IWF_ROUTER
    • DEFAULT_PWE3_IP_ROUTER

Displays and specifies the PWE3 service template. Service Type depends on Service Template.

Configuring services using a service templates improves the configuration efficiency.

NOTE:

After you select a service template, a dialog box is displayed, saying "After the template is changed, the parameters not contained in the new template may be lost. Are you sure to continue?" You can also select Apply the template data to the configured Objects.

Service Type

ETH, CES, ATM

NOTE:

Specifies the required service type based on the service configuration. To configure PWE3 ETH services, set this parameter to ETH; to configure PWE3 CES services, set it to CES; to configure PWE3 ATM services, set it to ATM. In this task of configuring ATM services, set it to ATM.

Displays and specifies the PWE3 service type.

Service ID

Auto-Assign, or manually enter it.

Default: Auto-Assign

Specifies the PWE3 service ID, which is unique on the entire network.

Service Name

For example: E-Line-1

NOTE:

The value of this parameter contains 1 to 64 bytes.

Displays and specifies the PWE3 service name.

Protection Type

Protection-Free, PW APS

Default: Protection-Free

Specifies the protection scheme of the PW.

This parameter is valid only when Mode is UNI-NNI.

If this parameter is set to PW APS, working and protection PWs need to be configured.

Displays and specifies the sink NE of a PW.

PW ID

Auto-Assign, or manually enter it.

For example, 35

Displays and specifies the identifier of a PW.

Signaling Type

Static

Displays and specifies the signaling type of a PW.

If you set Signaling Type to Static, you need to set the PW ingress label and PW egress label. If you set Signaling Type to Dynamic, the system automatically allocates the PW ingress label and PW egress label.

Forward Label

For example, 20

Displays and specifies the label that the service carries when entering a PW.

  • If you set Signaling Type to Dynamic, Forward Label is automatically allocated and cannot be specified manually.
  • If you set Signaling Type to Static, Forward Label can be automatically allocated or specified manually.

Reverse Label

For example, 20

Displays and specifies the label that the service carries when leaving a PW.

  • If you set Signaling Type to Dynamic, Reverse Label is automatically allocated and cannot be specified manually.
  • If you set Signaling Type to Static, Reverse Label can be automatically allocated or specified manually.

Forward Type

Static Binding

Displays and specifies the binding type of a forward tunnel.

Forward Tunnel

For example, NE1-NE2#1

Displays or specifies the name of a forward tunnel.

NOTE:

The OptiX OSN equipment supports only Static Binding.

Reverse Type

Static Binding

Displays and specifies the binding type of a reverse tunnel.

Reverse Tunnel

For example, NE2-NE1#1

Displays or specifies the name of a reverse tunnel.

NOTE:

The OptiX OSN equipment supports only Static Binding.

Encapsulation Type

MPLS

Displays and specifies the encapsulation type of a PW.

NOTE:

The OptiX OSN equipment supports only one tunnel type, namely, MPLS tunnel.

Table 3-397  Advanced PW parameters

Field

Value Range

Description

PW Trail

-

Displays the trail of a PW.

Direction

Bidirectional

Displays the direction of a PW.

PW Type

  • Ethernet
  • Ethernet Tagged Mode

Default: Ethernet

  • Ethernet: C-VLAN/S-VLAN tags of packets are encapsulated into PWs without changes, and transparently transmitted to downstream sites.
  • Ethernet Tagged Mode: A VLAN tag specified by Request VLAN is added to packets.

PWs of different types process their carried services differently. To tag the services carried by a PW, set PW Type to Ethernet Tagged Mode for the PW; otherwise, set PW Type to Ethernet.

Control Word
  • PWE3 ETH services: Not in use and Use preferred
  • CES services: Use required
  • ATM services: Not in use and Use required
Default:
  • PWE3 ETH services: Not in use
  • CES services: Use required
  • ATM services: Use required
NOTE:

In ATM ONE-to-ONE mode, Control Word must be set to Use required.

The Control Word parameter specifies the PW control word usage policy.

The control word is the 4-byte encapsulation packet header. The control word is used to identify the packet sequence or function as stuffing bits.

Value description:
  • Not in use: Indicates that the control word is not used.
  • Use preferred: Indicates that the control word is recommended.
  • Use required: Indicates that the control word must be used.
Association with other parameters:
  • If Control Word of the PW is Not in use, do not set Control Channel Type of the VCCV to CW; if Control Channel Type of the VCCV is CW, do not modify Control Word of the PW to Not in use.
  • Before changing the parameter value of a PW, you need to ensure that the PW is not bound with the service. After the change, you need to bind the PW with the service, and then check whether the parameter value is changed.
NOTE:

The PW control word must be consistently configured at the two ends of the PW.

Control Channel Type

None, CW, Alert Label

Default: CW

NOTE:
  • For PWE3 ETH services, Control Channel Type for PCXLG/PCXGA/PCXGB boards with PCBs of Ver.B can be set to CW; the default value for Control Channel Type is Alert Label.
  • For PWE3 ETH services, Control Channel Type for PCXLG/PCXGA/PCXGB boards with PCBs of Ver.A cannot be set to CW; the default value for Control Channel Type is Alert Label.
  • For PWE3 ETH services, Control Channel Type for PCXLX/PCXX boards can be set to CW; the default value for Control Channel Type is Alert Label.

The Control Channel Type parameter specifies the type of channels for transmitting VCCV packets.

VCCV packets are exchanged between PEs to verify connectivity of PWs.

Value description:
  • None: Indicates that the control word is not used to indicate the VCCV control channel information.
  • CW: Indicates that the control word is used to indicate the VCCV control channel information.
  • Alert Label: Indicates VCCV packets in Alert Label encapsulation mode.
Association with other parameters:
  • If Control Word of the PW is Not in use, do not set Control Channel Type of the VCCV to CW; if Control Channel Type of the VCCV is CW, do not modify Control Word of the PW to Not in use.
  • Before changing the parameter value of a PW, you need to ensure that the PW is not bound with the service. After the change, you need to bind the PW with the service, and then check whether the parameter value is changed.
VCCV Verification Mode

None, Ping

Default: Ping

VCCV Verification Mode specifies the verification mode for virtual circuit connectivity verification (VCCV) packets.

Value description:
  • None: Indicates that the VCCV function is disabled.
  • Ping: Indicates that VCCV is performed in ping mode.
Association with other parameters:

Before changing a parameter of a PW, ensure that the PW is not bound with any service. After the change, bind the PW with services, and then check whether the parameter value is changed.

Request VLAN

1-4094, Non-specified

Default: Non-specified

The Request VLAN parameter specifies the ETH request VLAN.

In the case of static PW, the local equipment adds the VLAN tag to the packets when before PW encapsulation. In the case of the dynamic PW, the opposite equipment adds the VLAN tag to the packets before PW encapsulation if the local equipment cannot add the VLAN tag.

Recommendations:

When the Request VLAN parameter is set to Non-specified, the packets are added with 0 VLAN tags.

Association with other parameters:

You need to set the PW Type parameter to Ethernet Tagged Mode.

Before changing the parameter value of a PW, you need to ensure that the PW is not bound with the service. After the change, you need to bind the PW with the service, and then check whether the parameter value is changed.
