Introduction

Note: Hierarchical virtual path (VP) tunnels are supported since version 12.0 in ATM Switch Processor (ASP) (Cisco Lightstream 1010) or 8540 Multiservice Switch Router (MSR) software. Please note that on the Cisco Lightstream LS1010, the Per-Flow Queuing Feature Card (FC-PFQ) is needed.

In this configuration, you need to transport circuit emulation service (CES) and LAN emulation (LANE) across the WAN. This example uses shaped hierarchical VP tunnels to ensure compliance with a traffic contract. When you use shaped VP tunnels with traffic parameters identical to what the service provider polices, no cells should be dropped in the service provider ATM network. The VP tunnel must be of the constant bit rate (CBR) service category in order to be shaped. It is the only shaped tunnel that the Lightstream 1010 and 8540 MSR currently support. Because this configuration uses hierarchical VP tunnels, virtual circuits (VCs) of multiple service categories can pass through the same hierarchical tunnel at the same time. Unlike shaped tunnels, hierarchical VP tunnels allow both LANE unspecified bit rate (UBR) switched virtual circuits (SVCs) and CES constant bit rate (CBR) permanent virtual circuits (PVCs) to pass through the same tunnel. Therefore, only one CBR VP needs to be purchased from the service provider.

In this example, it is assumed that the purchased CBR VP has a peak cell rate (PCR) of 10 Mbps and a cell delay variation tolerance (CDVT) of 500 cells. Before hierarchical VP tunnels are configured, hierarchical scheduling needs to be enabled with the atm hierarchical-tunnel command. After it is enabled, you must reload the switch for hierarchical scheduling to take effect. Hierarchical VP tunnels cannot coexist on the same physical interface with other types of connections (such as PVCs, SVCs, or unshaped or shaped tunnels). Refer to the documentation for more details. You must remove the configuration of the hierarchical VP tunnel before online removal of the card on whose port hierarchical tunnel is configured.

Please refer to the hardware documentation for limitations on the port numbers that can be used.

Network Diagram

This document uses this network setup:

LANE_VP_tunnels.gif

  • Device 5500-asp-f is VP switching. This function is typically performed by the service provider.

  • LANE services are defined on 8540 MSR. LAN Emulation Clients (LECs) are on 8540 MSR and 5500-asp-e. Note that LANE services are placed on the ATM switch in this example for simplicity. However, that is not the optimal location for LANE services.

  • The two private branch exchanges (PBXs) in the diagram use a CES CBR circuit. Refer to the PBX documentation for more information.
