This job is intended for Provider Connectivity Assurance Sensors (GT, LX, LT and so on).

This job can be used to set a variety of CFM (Connectivity Fault Management) settings:

  • Use the CFM General tab to set the DMM Test ID TLV State parameter.
  • Use the Interfaces tab to assign an interface for CFM.
  • Use the Defaults tab to set default parameters for MIP Half-Function (MHF).
  • Use the VSP tab to reflect VSP frames to the sender.

To set up a CFM Interface, Default & VSP configuration job

  1. Access the page Commission â–¶ Jobs.

  2. Set all common configuration job settings, as described in "Creating Configuration Jobs in GUI Mode" and "Creating Configuration Jobs Using Data Sets".

  3. Select CFM Interface, Default & VSP in the left pane. The CFM Interface, Default & VSP tab is displayed in the right pane.

  4. Complete all fields in the CFM interface, default & VSP tab as required. For more information on specific parameters, see the table below.

  5. Use the Add Button_New_Generic.png button or Duplicate Button_Duplicate.png button to add more interfaces, default values and VSPs as required.

    Note: When duplicating a row, always select the row to duplicate before clicking the Duplicate Button_Duplicate.png button.

  6. Click Apply, then click Close.

  7. Click the Refresh Button_Refresh_Generic.png button to refresh the user interface.

CFM interface, default & VSP tab (Commission â–¶ Jobs)

CFM General

Parameter Description
DMM Test ID TLV State A global NID parameter that applies to all DMM sessions.

Possible values:

  • False: The parameter is not applied.
  • True: A TestID TLV will be included in the DMM packet on transmission.

Interfaces

Parameter Description
Interface Name The name of the interface.
Assign Select this box to assign the interface to CFM.

Defaults

Parameter Description
Update defaults Select to enable updating of the Defaults settings on the target device. If not selected, the other parameters in the Defaults tab will not be applied.
LEVEL The default active MD level used by the MHF creation algorithm when no other lower active MD level applies.
MHF creation An MHF is a MIP Half-Function (MHF). The default parameters control MHF creation for VIDs that are not attached to a Maintenance Association within a VLAN component.

The MHF creation parameter indicates if the management entity can create MHFs for VIDs on which no Up MEP is configured.

Possible values are:

  • None: No MHFs can be created.
  • Default: Create MHFs if there is no lower active MD level or if there is a MEP at the next lower active MD level on the component port.
  • Explicit: Create MHFs only if there is a MEP at the next lower active MD level on the component port.
Sender Id permission Indicates what, if anything, is to be included in the Sender ID TLV transmitted in CCMs, LBMs, LTMs and LTRs.

Possible values are:

  • None: The Sender ID TLV is not to be sent.
  • Chassis: The Chassis ID Length, Chassis ID subtype, and Chassis ID fields of the Sender ID TLV are to be sent.
  • Manage: The Management Address Length and Management Address of the Sender ID TLV are to be sent.
  • Chassis and Manage: The Chassis ID Length, Chassis ID subtype, Chassis ID, Management Address Length, and Management Address fields are all to be sent.
VCE Name Name of the VCE that will be used for the MHF.

VCEs are optional. They are only required if you wish to define an "up" MEP.
Component ID Identifier for the bridge component of the VCE. This field should be left blank. A value will be assigned by the Provider Connectivity Assurance Sensors on which the job is executed.

VSP

Parameter Description
Edit VSP Select to enable editing of the VSP settings.

Note: If not selected, the other parameters of the VSP section will not be applied.
Level The MEG level of the reflector:
  • Frames with the MEG level equal to this setting are reflected.
  • Frames with the MEG level higher than this setting are forwarded.

Range: All, 0-7

Note: When All is selected, all frames are reflected.
Enable The state of the instance (disabled by default).
