A four-step wizard makes it easy to add (or edit) a session. The procedures provided in this section apply to all types of sessions. Tables provide detailed information about how to complete the fields in each of the steps. For more information that can help you set up sessions, see: - "Guidelines for Setting Up Performance Sessions" - "Performance Session Types" - "Managing Reflectors" - Explains how to add reflectors in advance in the (**Devices ▶ Reflectors** page). It is also possible to set up sessions in bulk (rather than one session at a time in the **Sessions** page). You can create sessions in bulk in two ways: - From the Legacy Orchestrator command line (Appliance Monitor). For more information, see *Administrative Operations*. - Using the Legacy Orchestrator REST API. For more information, see "Programming Interfaces". **To add a new session** 1. Access the **Sessions** page. The **Sessions** page is displayed with a list of all currently defined sessions. 2. Click ![PLUS BUTTON.png](https://cdn.document360.io/01d1de5e-a375-4fbc-aa82-666ac04c2113/Images/Documentation/PLUS%20BUTTON%287%29.png?sv=2026-02-06&spr=https&st=2026-11-13T16%3A00%3A15Z&se=2026-11-13T17%3A00%3A15Z&sr=c&sp=r&sig=5E5jQIvv2nih09v48K2NbeNS7OGLTpFb7efw30rXlHk%3D) above the list to add a new session.

Legacy Orchestrator allows users to associate labels with various entities (sessions, devices and so on). Labels can be used to group entities. You can filter various lists in Legacy Orchestrator by including a label in the query. Points to note about user-defined labels: - You can enter multiple labels (up to 12). - Labels can contain spaces. - Press Enter after each label. It will be displayed beside the Label field and you will be able to add another label. | | Description | Enter a description that indicates the purpose of the session and will help you and others identify the session. | | Session type | Click on one of the available session types: - Echo-ICMP (Layer 3) - Echo-UDP (Layer 3) - Ethernet OAM (Layer 2) - TWAMP (Layer 3) - 2xOneWay (Layer 3). You will be prompted for more information required for the session in a later step. | ## Step 2 – Termination points In Step 2, you select the sender and reflector termination points for the session. --- ***Note:** Sessions can be created without a Sender port. Sender port auto-assignment has a range from 14000 to 65535.* --- a. The image below highlights what you must do in Step 2. b. For more information about the fields in Step 2, see the table after this procedure. c. If the device you select as the **Reflector** is not already in the system list of reflectors (in the **Devices ▶ Reflectors** page), the **Create reflector** dialog is displayed. - See the image below that highlights what you must do in the Create reflector dialog. - For more information, see the table that describes the fields in the Create reflector dialog. d. If you need to return to Step 1, click on the green ball beside Enter session info. ![24.09_Adding, Editing and Duplicating Performance Sessions_2.png](https://cdn.document360.io/01d1de5e-a375-4fbc-aa82-666ac04c2113/Images/Documentation/24.09_Adding,%20Editing%20and%20Duplicating%20Performance%20Sessions_2.png?sv=2026-02-06&spr=https&st=2026-11-13T16%3A00%3A15Z&se=2026-11-13T17%3A00%3A15Z&sr=c&sp=r&sig=5E5jQIvv2nih09v48K2NbeNS7OGLTpFb7efw30rXlHk%3D) **Step 2 - Termination points – Field descriptions** **Sender** and **Reflector** sections include the following parameters | Column | Descriptioin | | --- | --- | | Name | Click in this field to open the **Choose a sender** dialog (or the **Choose a reflector** dialog).

The device name can be changed on the device itself. Any changes will be seen on Legacy Orchestrator after it synchronizes with the device. | | MAC address | ***Note:** The **MAC address** field is only displayed if you selected Ethernet-OAM in Step 1 (since Ethernet-OAM sessions take place on Layer 2)*. After you have selected a device in the **Choose a sender** or **Choose a reflector** dialog, the **Mac address** field is filled in with the MAC address of the interface (read from the device). | | Interface | ***Note:** The **Interface** field is displayed if you selected one of the Layer 3 session types in Step 1 (Echo-ICMP, Echo-UDP, TWAMP, 2xOneWay).* After you have selected an interface (of a device) in the **Choose a sender** or **Choose a reflector** dialog, the **Interface** field is filled in with the interface you selected. A logical interface configured on the device. Read from the device. | | Port | ***Note:** The **Port** field is only enabled if you selected one of the Layer 3 session types in Step 1 (Echo-UDP, TWAMP, 2xOneWay).* The number of the network port. Typically, the port number depends on the encapsulation used for the session. To find the port numbers and protocols typically used for each session type, see "Ports and Protocols per Session Type". | ![24.09_Adding, Editing and Duplicating Performance Sessions_3.png](https://cdn.document360.io/01d1de5e-a375-4fbc-aa82-666ac04c2113/Images/Documentation/24.09_Adding,%20Editing%20and%20Duplicating%20Performance%20Sessions_3%281%29.png?sv=2026-02-06&spr=https&st=2026-11-13T16%3A00%3A15Z&se=2026-11-13T17%3A00%3A15Z&sr=c&sp=r&sig=5E5jQIvv2nih09v48K2NbeNS7OGLTpFb7efw30rXlHk%3D) If the device you selected is not in the Devices Reflectors list, you must create a reflector.

Read from the interface. | | Capabilities | Indicates the types of session for which the interface can act as a reflector. Check all the reflection capabilities that apply to the device. TWAMP Sessions: Only check one of the TWAMP options. If you check both options, you will not be able to create the reflector. - twamp-rf (stateful TWAMP) - twamp-sl-rf (stateless TWAMP) Echo Sessions: - echo-udp-rf - echo-icmp-rf Ethernet OAM Sessions: - ethlb-rf - ethdm-rf - ethvs-rf To determine the reflection capabilities of Accedian devices, see "Sender and Reflector Capabilities of Accedian Devices".

TWAMP-Control can be used with stateful and stateless reflectors. For more information about TWAMP sessions and the TWAMP- Control protocol, see "TWAMP Sessions". | | IP address | The IP address of the TWAMP-Control Server. Typically, the TWAMP- Control Server resides on the reflector. If this field is left blank, TWAMP-Control messages will be sent to the management IP address of the reflector. If you specify a different IP address for the TWAMP-Control server, the TWAMP-Control messages will be sent to the specified address. | | Port | The number of the UDP port to be used on the TWAMP-Control Server for control messages. The default port is 862. | | DSCP | Sets the traffic classification method to use when transmitting TWAMP-Control messages. | | VLAN priority | Sets the VLAN priority to use when transmitting TWAMP-Control messages. The default VLAN priority is 0. | | Legacy Mode | Check this box if the reflector does not accept current Time-of-Day as the STARTTIME parameter in the TWAMP-Control protocol setup. | ## Step 3 – Session profile In Step 3, you configure session parameters. a. The image below highlights what you must do in this step. b. For more information about the fields in Step 3, see the table. c. If you need to return to a previous step, click on the green ball beside the step. ![24.09_Adding, Editing and Duplicating Performance Sessions_4.png](https://cdn.document360.io/01d1de5e-a375-4fbc-aa82-666ac04c2113/Images/Documentation/24.09_Adding,%20Editing%20and%20Duplicating%20Performance%20Sessions_4.png?sv=2026-02-06&spr=https&st=2026-11-13T16%3A00%3A15Z&se=2026-11-13T17%3A00%3A15Z&sr=c&sp=r&sig=5E5jQIvv2nih09v48K2NbeNS7OGLTpFb7efw30rXlHk%3D) **Step 3 - Session profile – Field descriptions** **Sender** and **Reflector** sections include these parameters | Column | Description | | --- | --- | | Payload size (bytes) | Size of the packet in the session stream.
