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:
ƒ LAN connectivity between the Avaya and ProCurve products.
ƒ Registration of Avaya H.323 IP Telephones with Avaya Communication Manager.
ƒ Registration of Avaya SIP IP Telephones with Avaya SIP Enablement Services.
ƒ Verification of the DHCP relay configuration.
ƒ VoIP calls over Layer 2 and Layer 3 connections.
ƒ Inter-office calls using G.711 mu-law & G.729 codecs, conferencing, and
sending low priority data traffic over the LAN.
ƒ Verifying that QoS directed the voice signaling and voice media to the higher priority
egress queue based on the packets’ DSCP value.
ƒ Verifying 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.
