Avaya Solution & Interoperability Test Lab Application Notes for Extreme Networks Aspen 8810 with Avaya C364T-PWR Converged Stackable Switch, Avaya S8500 Media Server and Avaya G650 Media Gateway - Issue 1.0 Abstract These Application Notes present a sample quality of service configuration for the Avaya S8500 Media Server with an Avaya G650 Media Gateway using Extreme Networks Aspen 8810 and Avaya C364T-PWR Converged Stackable Switch.
1. Introduction The network diagram in Figure 1 shows two offices. The office labeled “Main Office” uses an Avaya S8500 Media Server with an Avaya G650 Media Gateway. The office labeled “Branch Office” uses Avaya IP telephones. The Extreme Networks Aspen 8810 is used in the main office, and the Avaya C364T-PWR Converged Stackable Switch is used in the branch office. The Aspen and the Avaya C364TPWR are connected through a 1000 Base-X (Fiber) or 100 Base-T link.

with VLAN 0 as clear traffic. Therefore, it is recommended to enable DiffServ examination on these ports. The Avaya C364T-PWR Converged Stackable Switch supports 802.1p/Q priority for Layer 2 traffic, and can be configured to trust 802.1p/Q priority (CoS) or DSCP or both for Layer 3 traffic. 3.2.2. Overview of Extreme Networks QoS Features QoS profiles define how the Extreme Networks switch will respond to various categories of traffic.
7. Since Extreme Networks switches treat VLAN 0 as clear traffic (untagged VLAN), it does not matter if 802.1Q is enabled on the Avaya S8500 Media Server and the IPSI of the Avaya G650 Media Gateway. The Avaya C364T-PWR Converged Stackable Switch trusts 802.1p/Q priority for Layer 2 traffic, and is configured to trust CoS-DSCP for Layer 3 traffic. By configuring to trust CoSDSCP, the Avaya C364T-PWR will use a higher CoS value mapped from 802.p/Q priority and DSCP. The Avaya C364T-PWR will preserve 802.
Switch are configured with both untagged (or native) VLAN 89 and tagged (or static) VLAN 88 for the port connected to the IP telephone. Since the DHCP server is on the untagged VLAN, the untagged DHCP request will reach the DHCP server directly. The DHCP server associates this request with the 192.168.89.0 scope and returns a reply with Option 176 string, instructing the IP telephone to enable 802.1Q tagging with VLAN ID 88.

The following two screens display the configurations of the C-LAN (01A02) and the MEDPRO (01A03).
Use the command change ip-network-region to configure the QoS and other parameters for a network region. It is recommended to enable IP direct for intra-region and inter-region connections. RSVP is not used and is disabled by default. The Avaya components including CLAN, MEDPRO, IP telephones, and Softphones will receive QoS (802.1p priority 7 and DiffServ 56) and other parameters from network region 1 in the sample configuration.
Use the command change ipserver-interface to configure the communication to the IPSI. The following screen shows that DiffServ 56 is configured for the communication from the Avaya S8500 Media Server to the IPSI of the Avaya G650 Media Gateway. change ipserver-interface 1 Page 1 of IP SERVER INTERFACE (IPSI) ADMINISTRATION - PORT NETWORK 1 IP Control? y Ignore Connectivity in Server Arbitration? n Primary IPSI -----------Location: 1A01 Host: 192.168.87.
5. Configuring Extreme Networks Aspen 5.1.1. Configuring VLAN and Port The following commands configure a VLAN “VLAN 87” corresponding to the 192.168.87.0 network, which is used for the Avaya S8500 Media Server, and IPSI of the Avaya 650 Media Gateway. Note that the ports connecting to these Avaya components are all untagged.
The following commands configure VLAN87, VLAN88, and VLAN89 with their IP addresses. Since the Extreme Networks Aspen disables IP forwarding for all the configured VLANs by default, IP forwarding must be enabled on the VLANs that require IP forwarding. Since VLAN87 is only used for the communication between the S8500 Media Server and the IPSI, IP forwarding does not have to be enabled on this VLAN.
The uplink 1000 Base-X port 1/51 is configured with dot1q with vlan-binding-mode to the configured VLANs. The native VLAN is configured to VLAN 1. The same configuration applies to a 100 Base-T uplink if a 100 Base-T link is used. C360-1(super)# set port vlan 1 1/51 C360-1(super)# set trunk 1/51 dot1q C360-1(super)# set port vlan-binding-mode 1/51 bind-to-configured 6.1.2. Configuring QoS The Avaya C364T-PWR Converged Stackable Switch supports four hardware queues. The 802.
7. Interoperability Compliance Testing This Interoperability Compliance Test included QoS testing between the Extreme Networks Aspen 8810, the Avaya S8500 Media Server, the Avaya G650 Media Gateway, and the Avaya 4600 Series IP telephones. Basic feature functionality was performed as part of the compliance testing. 7.1. General Test Approach Connectivity and QoS test cases were performed manually. During QoS testing, an Ixia data generator was used to generate low priority traffic.
10. Conclusion Extreme Networks Aspen 8810 Switch was compliance-tested with the Avaya S8500 Media Server, Avaya G650 Media Gateway, Avaya C364T-PWR Converged Stackable Switch and Avaya IP telephones. All feature functionality and QoS test cases completed successfully. 11.
