1 Avaya Solution & Interoperability Test Lab A Sample Configuration using Cisco Catalyst 3750E-24PD to Provide Power over Ethernet to Avaya IP Telephones - Issue 1.0 Abstract These Application Notes describe the configuration of the Cisco Catalyst 3750E-24PD to provide Power over Ethernet (PoE) to Avaya 1600, 4600 and 9600 Series IP Telephones registered to Avaya Communication Manager. 1 of 15

2 1. Introduction Power over Ethernet (PoE) allows both power and data to be simultaneously carried over standard Ethernet cables. PoE-enabled Ethernet switches can supply power directly to Ethernet devices, thereby simplifying installation and removing the need for separate power supplies for those devices. The IEEE 802.3af defines a standard protocol to be used by Power Sourcing Equipment (PSE) and Powered Devices (PD). The Catalyst 3750E-24PD is IEEE 802.3af compliant and can provide inline power to the Avaya 1600, 4600 and 9600 Series IP Telephones which are IEEE 802.3af compliant powered devices. Figure 1 shows the configuration used for PoE. All ports on the switch are PoE enabled by default. Figure 1: Power over Ethernet Network Configuration 2 of 15

4 3. Configure Avaya G450 Media Gateway This section shows the necessary steps in configuring the Avaya G450 Media Gateway. Step Description 1 Configure the Avaya G450 Media Gateway Connect to the Console port of the V10 module with serial cable provided for gateway. Start Hyperterminal session interface and log in using appropriate credentials. 2 Create a vlan G (super)# set vlan 119 name voice 3 Assign an IP address to vlan G (super)# int vlan 119 G (super-if:Vlan 119)# ip address Configure Ethernet port The set port command is used to configure port 10/6. Classify the port as valuable so if link fails a notification is generated. G (super)# set port vlan enable10/6 G (super)# set port duplex 10/6 full G (super)# set port speed10/6 1GB G (super)# set port vlan /6 G (super)# set port classification 10/6 valuable 5 Configure port mode This command configures the port 10/6 to be bound to vlan VOICE which is the configured on the gateway G (super)# set port vlan-binding-mode 10/6 bind-to-configured 6. Create a trunk port This command sets the port 10/6 to be a trunk port. Use the set trunk command to configure the VLAN tagging mode of the port. The dot1q parameter specifies IEEE 802.1Q tagging on a Fast Ethernet or Gigabit Ethernet port. G (super)# set trunk 10/6 dot1q 4 of 15

5 4. Configure Endpoints in Avaya Communication Manager This section shows the necessary steps in configuring the endpoints in Avaya Communication Manager. Step Description 1. Start a SSH session and connect to the Avaya S8300 server IP address. Log in using appropriate credentials. 2. From the command line connect to SAT (System Access Terminal). Log in using appropriate credentials. 3. Add Stations Extension numbers need to be defined for all the phones listed in Table 1. The command add station is used to configure a phone extension. Use the SAT help command to acquire a list of the models available for the release of Avaya Communication Manager software. The Type parameter is selected for the model type or nearest representative model listed in the software database. A generic Security Code is allocated to all the phones under test. The Name for the particular phone to be used at this extension can be given as a specific name or the extension number of the phone tested. Refer to the example below. Type: 4621 Security Code: 1234 Name: 4621SW 5 of 15

6 Step Description 4. Configure DiffServ /TOS and 802.1p/Q parameters in Avaya Communications Manager Avaya IP Telephones receive Quality of Service (QoS) tagging information when it registers with Avaya Communication Manager. The QoS values are configured using the change ip-network-region 1 command to access and set the DiffServ/TOS and 802.1p/Q parameters using sat interface into Avaya S8300 media server. In the example below the IP telephones are registered in network region 1. The Diffserv/Tos parameters are set at 46 for both Audio and Video packets. These values will appear on the phone as L3 Audio and Signalling values. Similarly for the 802.1P/Q parameters both are set at 6. These values will appear on the phone as L2 Audio and Signalling values. Refer to the following section 6.4 for details on accessing this information on the phone. 5. Use the Save Translations command to save the settings. 6 of 15

10 8. Cisco 3750E-24PD Switch PoE Test Results All Power over Ethernet test cases completed successfully IEEE 802.3af PoE implementation on the Avaya Powered Devices and Cisco Catalyst 3750E-24PD In June 2003, the IEEE approved a standard for Power over Ethernet. The maximum power is 15.4W per PSE port and the maximum power delivered to a powered device, accounting for cable loss, is 12.95W. Optionally, powered devices may also be classified based on the maximum power the device will draw. Cisco Catalyst 3750E-24PD and Avaya Powered Devices support this optional classification. The Cisco Catalyst 3750E-24PD can detect the Avaya Powered Devices with the correct classification and deliver the appropriate power. The Cisco Catalyst 3750E-24PD is IEEE 802.3af compliant and Enhanced Power over Ethernet is Cisco's extension to the standard that delivers up to 20 Watts per port. The Cisco Catalyst 3750E-24PD provides inline power to the Avaya 1600, Avaya 4600 and Avaya 9600 Series IP Telephones which are IEEE 802.3af compliant. Table 2, Table 2.1 and Table 3 below list the IEEE 802.3af class allocated power and measured power of the selected Avaya IP telephones when connected to the Cisco Catalyst 3750E-24PD switch. Power to the phones is listed for when phones are in idle mode.

Class PSE Output Max Power (W) Treat as Class 0 Table 3: IEEE 802.3af Power Classifications Configuring Inline Power on the Cisco Catalyst 3750E-24PD The Cisco Catalyst 3750E-24PD supports 450Watts of inline power and should support Class 3 powered devices on all 24 ports. The testing associated with these Application Notes did not cover loading of all ports. The following describes how the Cisco Catalyst 3750E-24PD interacts with powered devices. 1. PoE-capable ports are configured to auto mode by default. This means that powered device discovery is enabled. If the budget inline power is exceeded, there is no guarantee which device will receive power. 2. Power over Ethernet ports may be configured to never provide inline power. The ports connected to the Avaya IP Telephones must use the default auto mode or static mode in order to be powered up by the Cisco Catalyst 3750E-24PD. 11 of 15
