The Avaya IP telephones and softphones will receive the QoS parameters from network region 1 upon their successful registration. DiffServ DSCP 48 and 802.1p priority 6 are used in the sample configuration. The C-LAN and Media Processor also use these QoS parameters because they are configured to this network region. Avaya IP softphones use DiffServ for QoS Q/p priority was not used because the NIC of the PC running the IP softphone does not support 802.1Q/p. The following shows the network region 1 configuration. Codec Set 1 is configured for the calls in network region 1. display ip-network-region 1 Page 1 of 19 IP NETWORK REGION Region: 1 Location: Home Domain: Name: Intra-region IP-IP Direct Audio: yes AUDIO PARAMETERS Inter-region IP-IP Direct Audio: yes Codec Set: 1 IP Audio Hairpinning? y UDP Port Min: 2048 UDP Port Max: 3028 RTCP Reporting Enabled? y RTCP MONITOR SERVER PARAMETERS DIFFSERV/TOS PARAMETERS Use Default Server Parameters? y Call Control PHB Value: 48 Audio PHB Value: P/Q PARAMETERS Call Control 802.1p Priority: 6 Audio 802.1p Priority: 6 AUDIO RESOURCE RESERVATION PARAMETERS H.323 IP ENDPOINTS RSVP Enabled? n H.323 Link Bounce Recovery? y Idle Traffic Interval (sec): 20 Keep-Alive Interval (sec): 5 Keep-Alive Count: 5 5 of 17

A similar configuration applies to the M12PWR switch MNO M24PWR Switch Layer Two Configuration Connect a COM port on a computer to the console port of the M24PWR switch and log in with the proper user name and password. Follow [B]asic Switch Configuration... System [I]P Configuration to configure the system IP address on the M24PWR. The following screen shows the configuration. Basic Switch Configuration -> System IP Configuration Menu MAC Address: 00:C0:8F:0E:A2:44 IP Address: Subnet Mask: Default Gateway: DHCP Mode: Disabled <COMMAND> Set [I]P Address Set Subnet [M]ask Set Default [G]ateway Set [D]HCP Status Set DHCP [R]enew [Q]uit to previous menu It is recommended to configure different VLANs for an Avaya IP telephone and the attached PC. In the sample configuration, VLAN 110 is configured as the Voice VLAN and VLAN 120 is configured as the data VLAN. VLAN 120 is configured as a native VLAN while VLAN 110 is configured as a tagged VLAN on all PoE ports. VLAN 110 and VLAN 120 must be configured 6 of 17

9 The M12PWR and M24PWR switches support four hardware queues. By default, CoS values 0-1 are mapped to queue 1, CoS values 2-3 to queue 2, CoS values 4-5 to queue 3 and CoS 6-7 values to queue 4. When QoS is enabled, the M12PWR and M24PWR switches support QoS based on CoS values. Note that the M12PWR and M24PWR decide CoS values based on 802.1p priorities. For example, 802.1p priorities 0 to 7 correspond to CoS values 0 to 7. To avoid any potential QoS issue for VoIP traffic, it is recommended to configure voice VLAN 110 to a high priority with CoS 6, and then re-mark the packets in VLAN 110 with DSCP 48 for consistency. Since the IP softphones do not use 802.1p for QoS, it is recommended to map DSCP 48 (used by the IP softphones) to CoS 6. Follow [A]dvanced Switch Configuration...

PoE Configuration On MNO M12PWR and M24PWR Switches IEEE 802.3af defines a standard protocol to be used by power sourcing equipment (PSE) and powered devices (PD). The M12PWR and M24PWR switches are IEEE 802.3af compliant PSEs and can provide inline power to the Avaya 4600 Series IP Telephones and Avaya Wireless Access Points, which are IEEE 802.3af compliant PDs. Table 2 shows the detected classes and typical (e.g., on-hook/idle) power consumption for the Avaya IP Telephones and Wireless Access Points measured from the M12PWR and M24PWR switches.

13 5. DHCP Server Configuration The DHCP Server is configured to support the PCs and the Avaya IP telephones in Figure 1. When an IP telephone initially sends an untagged DHCP request, the DHCP server associates this request with the scope and returns a reply with Option 176 string, instructing the IP telephone to use VLAN ID 110 (as indicated in the first row of Table 3). The IP telephone receiving this reply will release the supplied IP address and issue a new DHCP request with VLAN ID 110. The Cisco Catalyst will relay this request to the DHCP server. The DHCP server will reply with an IP address from the scope as well as several parameters in the Option 176 string (as indicated in the second row of Table 3 below). The IP telephone will use Option 176 parameters to register to the C-LAN in the Avaya G650 Media Gateway. Note that the PC will ignore the Option 176 values. Therefore, no new DHCP request is issued. Table 3 shows the DHCP summary configuration: DHCP Option 3 Option 176 String Notes Scope Router L2QVLAN=110 For PCs and Phones MCIPADD= ,TFTPSRVR= For IP telephones C-LAN IP: Table 3 DHCP Configuration Summary 6. Configuring Cisco Catalyst 6509 The Cisco Catalyst 6509 being used in this configuration supports Layer 3 routing on its Multi- Layer Switch Feature card. In the sample configuration, VLAN 10 is configured for the Avaya S8500 Media Server and the IPSI of the Avaya G650 Media Gateway. VLAN 110 is configured for the IP telephones, the C-LAN and Media Processor of the Avaya G650 Media Gateway. VLAN 120 is configured for the PCs. The following shows the related Layer 3 configuration including DHCP relay is the IP address of the DHCP server. interface Vlan10 ip address interface Vlan110 ip address ip helper-address interface Vlan120 ip address VLAN 10 configuration VLAN 110 configuration DHCP Relay to the DHCP server. VLAN 120 configuration Port 4/26 on the Cisco Catalyst 6509 is connected to the M24PWR switch. The following screen shows how to configure port 4/26. The same configuration should also apply to any other ports connected to the M12PWR and M24PWR switches. To reduce broadcast/multicast messages from the other VLANs, port 4/26 is configured to support VLAN 1, 110 and 120 only. 13 of 17

Verification Steps Verify that the Avaya S8500 Media server recognizes the Avaya G650 Media Gateway. Verify that all the IP telephones and softphones can register with the C-LAN of the Avaya G650 Media Gateway. Verify that an IP telephone and the attached PC are on different VLANs through the DHCP server. While generating data traffic to overload the link between the Cisco Catalyst 6509 and the MNO PoE switches, make a call and verify that voice quality is acceptable across the congested link. 8. Conclusion As illustrated by these Application Notes, MNO M12PWR and M24PWR switches work well with Avaya IP telephones and softphones. Avaya IP telephones can draw power from the MNO PoE switches. With the recommended QoS configuration, the MNO PoE switches can prioritize Avaya VoIP traffic over data traffic. 9.
