Overview

When building an AVB network with one or more Meyer Sound AVB products, use an AVB-compliant device, preferably one certified by the Avnu Alliance. Click the following link to see the Avnu-certified Extreme Networks Summit Family switches: http://www.extremenetworks.com/

Note

Meyer Sound cannot guarantee the performance of switches not certified by the Avnu Alliance.

To determine the exact number of switches required to meet your application requirements, contact Meyer Sound Technical Support.

The procedures in this guide use a web browser and require a second-generation Extreme Networks Summit Family switch. To make sure you have the latest firmware in your switch, click the link below and follow the instructions:

Extreme networks switch quick start

The network ports on the G2 Extreme Networks switches do not have an associated IPv4 address.

Note

  • This method may not work if a switch has already been configured. If that is the case, program the Management VLAN with the same IPv4 address and subnet as the default VLAN.

  • If you cannot access the switch via a web browser, you may need to reset your switch from a terminal window. To do so, follow the steps in Resetting the Switch from a Terminal Window.

Procedure. To set an IPv4 address by connecting to the Management port:

  1. Disable WiFi on your computer.

  2. Set your computer's wired network interface controller to DHCP.

  3. Connect a network cable to the USB Management port on the Extreme Networks switch.

  4. Locate the last four digits of your switch’s MAC address (printed on a label on the switch).

  5. Open a web browser and type the following URL into the address bar:

    http://0xa9fe followed by the last four digits of the MAC address (e.g., http://0xa9fedx17).

  6. When you are prompted to log in, type admin as the user name and leave the password field blank.

Resetting the AVB switch

You may want to reset the switch to factory default settings in some circumstances. The following procedure removes the user settings from the switch, including the IPv4 address, but does not remove the AVB license.

Procedure. To reset the AVB switch:

  1. If you are not already logged in, connect to a network port, and set the user IP to a compatible subnet of the switch.

  2. When prompted to log in, type admin for the user Login, leave the Password field blank and click Sign in (or press Enter).

  3. In Dashboard click Apps, and then select CLI Terminal.

  4. In the terminal window, type the command unconfigure switch all.

  5. Type y to confirm and then press Enter.

  6. When the switch reboot is complete, you must log in again to reconnect to the switch.

  7. You will be asked several questions about security settings. We recommend accepting the standard settings (indicated by the capital letter).

    For example, type N for no for these options [y/N/q].

    To accept all standard settings without seeing additional questions, type q. This can be done for the first or any subsequent question.

Resetting the switch from a terminal window

In some cases, you may need to reset the switch from a terminal window. To do so, you will need:

  • USB-to-serial adapter

  • Serial-to-RJ45 adapter (this should come with your Extreme switch)

  • serial cable

Procedure. To reset the switch from its console port:

  1. Connect the USB-to-serial adapter to your computer.

  2. Insert the serial-to-RJ45 adapter into the console port of the switch.

    console-port.jpg

  3. Use the serial cable to connect both adapters.

  4. Login into the switch via a terminal window.

    Note

    The default username is admin and the default password is empty.

  5. Press Enter twice.

  6. When connected, type the command unconfigure switch all , and then press Enter.

These steps will reset the switch and restore it to factory defaults, after which you should be able to configure the switch via the steps outlined in Extreme networks switch quick start.

For additional information, see the following resources available from the Extreme Portal:

AVB is the common name for a set of technical standards that provide improved synchronization, low latency, and reliability for switched Ethernet networks. AVB is now often referred to as AVB/TSN or just TSN (Time Sensitive Networking).

Avnu Alliance

gPTP precisely synchronizes distributed systems in time-critical applications. This is done through the high-precision, fast synchronization of the timers of all network participants in a distributed system as defined by IEE 801.1AS-2020.

MSRP provides a mechanism for endpoints to reserve network resources that will guarantee the sending and receiving of data streams across a network with the requested QoS. MSRP is one of the core protocols required on an AVB device (talker, listener, and switches).
