To create a VLL service

Purpose

VLL Apipe services are configurable only on the 7450 ESS in mixed mode, 7750 SR, 7950 XRS, and 7705 SAR.

VLL Hpipe services are configurable only on the 7705 SAR and 7705 SAR-M.

In order to configure a VLL Hpipe service on a supporting NE, the daughter card MDA Mode must be set to cem-fr-hdlc-ppp. For more information, see To configure an MDA . Only ports that are configured with an Encap Type of HDLC can be mapped to an Hpipe SAP. For more information, see To configure Ethernet ports .

VLL Cpipe services are configurable only on the 7750 SR, 7705 SAR, 7210 SAS-M, and 7450 ESS NEs. Consider the following when creating a VLL Cpipe:

  • The Time Slots parameter of the DS0 channel must be configured with at least one time slot.

  • Time slots are automatically configured for unstructured E1 and T1 endpoints

  • The Clock Source parameter of the DS1 channel must be set to Node-Timed.

Steps
 

Choose Create→Service→VLL→Epipe (Ethernet to Ethernet/ATM/FR/CEM) | Apipe (ATM to ATM/FR) | Ipipe | Fpipe (FR to FR) | Hpipe (HDLC to HDLC) | Cpipe (CEM to CEM) from the NFM-P main menu. The VLL Service (Create) form opens.


Select a customer in the Customer panel.


Configure the required general parameters.

The Service ID and SVC Mgr Service ID parameters are configurable when the Auto-Assign ID parameter is disabled.

The Default VC ID parameter is configurable when the Inherit Service ID Value parameter is disabled.


This operation cannot be reversed.

If you will be using an MLPPP link for Epipe bandwidth management, perform the following steps to convert bandwidth units to Kbps:

  1. Choose Administration→System preferences from the NFM-P main menu. The System Preferences form opens.

  2. Choose the Services tab.

  3. Disable Service Bandwidth Management.

  4. Click Execute in the Convert to Kbps parameter.

  5. Click Yes in the warning dialog box to proceed.

  6. Enable Service Bandwidth Management.


If you enabled the Automatic SDP Binding/PBB Tunnel Creation parameter in Step 3 , select a tunnel selection profile in the Auto Tunnel Selection panel.


Save the changes and close the forms.

You can use the topology maps to view the service. See Chapter 4, Topology map management for more information about service topology maps.
