1. Introduction

These Application Notes describe the configuration of a Voice over IP (VoIP) solution using ProCurve 5400, 3500 and 2600 Series Switches by HP connected to an Avaya Communication Manager, Avaya SIP Enablement Services, Avaya Modular Messaging and Avaya IA770 INTUITY AUDIX. Compliance testing emphasis was placed on verifying the prioritization of VoIP traffic and voice quality in a converged VoIP and data network scenario. Quality of Service (QoS) based on Layer 2 Priority (802.1p) and Layer 3 Differentiated Services (Diffserv) was implemented across the network to prioritize voice traffic over the LAN. The Avaya IP Telephones get QoS priority settings from Avaya Communication Manager and are enforced in the network by the ProCurve Switches. To verify VoIP traffic was given priority over data traffic tests were performed by over subscribing the LAN interfaces with low priority data traffic and verifying that acceptable voice quality was achieved when calls were routed over all of the LAN interfaces. Compliance testing included QoS, throughput, link aggregation, rapid spanning tree, load balancing, Open Shortest Path First (OSPF), Direct IP Media connectivity and the G.711 and G.729 codecs.

1.1. ProCurve Switch 5400zl/3500yl Series Switch

The ProCurve Switch 5400zl series includes a 6-slot and a 12-slot chassis and the ProCurve Switch 3500yl series includes 24-port and 48-port stackables. The foundation for all these switches is a purpose-built, programmable ProVision ASIC that allows networking features, such as QoS and security, to be implemented in a scalable yet granular fashion. The ProCurve Switch 5400zl/3500yl series have options for a variety of Gigabit Ethernet (GigE) interfaces, integrated Power over Ethernet (PoE) on all 10/100/1000Base-T ports, and 10-GigE capability. The ProCurve Switch 5400zl/3500yl series are IEEE 802.3af compliant for PoE and provide up to 15.4 Watts per port. A redundant external power supply is also available as an accessory.

1.2. ProCurve Switch 2600 Series Switch

The ProCurve Switch 2600 series is a collection of stackable, multi-layer, managed switches with 48, 24, or 8 auto-sensing 10/100 ports and dual-personality ports for 10/100/1000 or mini gigabit interface converter (GBIC) connectivity. The ProCurve Switch 2600 Series is IEEE 802.3af compliant for PoE and provide up to 15.4 Watts per port. A redundant external power supply is also available as an accessory.

2. Hardware Configuration

The configuration in Figure 1 shows a single site converged VoIP and data network with multiple closets and labs configured with link aggregation, rapid spanning tree, load balancing and OSPF.

For compliance testing, a centralized corporate DHCP server was used. To better manage the different traffic types, the voice and data traffic were separated onto different VLANs.
