Avaya 2600, 5400ZL, 3500YL manual Interoperability Compliance Testing, General Test Approach

9. Interoperability Compliance Testing

Interoperability compliance testing covered feature functionality, serviceability, and performance testing.

Feature functionality testing focused on the QoS and VLAN implementation in the Avaya/ProCurve configuration. Specifically, compliance testing verified that when the ProCurve Switch interfaces are over subscribed with low priority data traffic, the higher priority VoIP media and signaling traffic still got through and achieved good voice quality. Prioritization of voice traffic was achieved by implementing Layer 3 DiffServ-based QoS and Layer 2 priority (801.p). Voice and data traffic were segmented in the enterprise network using VLANs.

QoS and performance testing was verified by making voice calls while a traffic generator generated low priority data traffic to simulate a converged network. At the end of the performance test, it was verified that the network devices continued to operate successfully.

Serviceability testing was conducted to verify the ability of the Avaya/ProCurve VoIP solution to recover from adverse conditions, such as power cycling network devices and disconnecting cables between the LAN interfaces. In all cases, the ability to recover after the network normalized was verified.

9.1. General Test Approach

All feature functionality test cases were performed manually. The general test approach entailed verifying the following:

ƒLAN connectivity between the Avaya and ProCurve products.

ƒRegistration of Avaya H.323 IP Telephones with Avaya Communication Manager.

ƒRegistration of Avaya SIP IP Telephones with Avaya SIP Enablement Services.

ƒVerification of the DHCP relay configuration.

ƒVoIP calls over Layer 2 and Layer 3 connections.

ƒInter-office calls using G.711 mu-law & G.729 codecs, conferencing, and sending low priority data traffic over the LAN.

ƒVerifying that QoS directed the voice signaling and voice media to the higher priority egress queue based on the packets’ DSCP value.

ƒVerifying that Avaya Modular Messaging & Avaya IA770 INTUITY AUDIX voicemail and MWI works properly.

The performance tests were performed by over subscribing the lines with low priority data and verifying that VoIP traffic was prioritized and that good voice quality was achieved when calls were routed over all of the LAN interfaces.
