VP (Virtual Path) Switching and Tunnels

Introduction

This document provides a sample configuration for LAN emulation (LANE) and circuit emulation service (CES) with the use of permanent virtual circuits (PVCs) in unshaped virtual path (VP) tunnels.

Prerequisites

Requirements

These sample configurations are based on these prerequisites:

• You need to transport CES and LANE across the WAN. Therefore, Cisco recommends ASP-PFQ on the LS1010 to ensure good clocking operations. Cisco also recommends RP-NetClock-3 on the 8540-MSR for the same reason.

• This example uses unshaped VP tunnels.

• Because LANE uses unspecified bit rate (UBR) SVCs, CES uses constant bit rate (CBR) PVCs. Also, since this configuration uses regular VP tunnels, you must have two VP tunnels (one for each service category: CBR and UBR). You might use only one VP tunnel if you used the hierarchical type.

• Since unshaped tunnels can be of any service category, this example has a CBR VP tunnel that can only contain CBR VCs. It is used for CES CBR PVCs (labeled VPI1 in the network diagram).

  Note:  The VPI number is locally significant to the switch port. Therefore, you can have the same VPI number on the same switch, but two different switch ports.

• Because a CBR VP tunnel cannot transport non-CBR VCs, you must create another VP tunnel for LANE (which uses UBR service category VCs). Therefore, the second VP tunnel (labeled VPI2 in the network diagram) is a UBR VP tunnel with UBR LANE SVCs that pass through it.

• You need to purchase two VPs from the service provider. These are CBR and UBR.

• In this example, it is assumed that the CBR VP has a peak cell rate (PCR) of 10 Mbps and a cell delay variation tolerance (CDVT) of 500 cells.

• Device 5500-asp-f is for VP switching. The service provider typically performs this function.

• LANE services are defined on 8540-MSR. LAN Emulation Clients (LECs) are on 8540-MSR and 5500-asp-e.

  Note: 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. For details on how to configure circuit emulation, refer to the CES documentation.

Show Commands for VPs and VCs within the VP

Use the show commands in this section to view details about each VP and VC within the VP.

In this example, in order to ensure that the signalling VCs go through both VPs, signalling is disabled on the main interface. The command used to do this is no atm signalling enable. The same has been done on the 8540-MSR.

Well known VCs change their VPI number from zero to the VPI number of the VP tunnel. Well known VCs are also of the same service category as the VP tunnel. Therefore, for one VP tunnel the signalling VC is UBR, and the other is CBR. Use the show atm vp interface atmx/y/z n m and show atm vc interface atmx/y/z.n n m commands to view information about the service categories.
