Configuring Cisco SG350 Switch for Shure devices and Dante


The following guide is designed to help you configure your Cisco SG350-series network switch for Dante and AES67 networks.

Before You Begin

  1. Ensure that you have a Cisco SG350-series switch. This article only applies to Cisco SG350-series switches.
  2. Decide how IP Addresses will be managed. It is fine to use DHCP (e.g., from a Crestron server), Static, or Self-Assigned addresses. If you are using Static IP Addresses, create a spreadsheet to keep track of each device's address. We have included a sample spreadsheet at the end of this document. We suggest tracking the device make, model, MAC Address(es), IP Address(es), firmware version, date purchased, and date installed. Include your switch in the list.

Configuring a Cisco SG350-series Switch for Shure Dante Devices

  1. Under the Administration menu, select Management Interface > IPv4 Interface. Click the Add button, and set an IP address within your Network Audio subnet, set the correct Subnet Mask (Network Mask). Click Apply. The warning will ask if you want to replace the existing IP Address, click OK. Apply changes and reconnect to the switch if needed.
  2. Under the Port Management menu, select Green Ethernet > Properties. Ensure Energy Detect Mode and 3 Energy Efficient Ethernet is disabled. Verify that all ports show 802.3 as Disabled under the Operational column. Click Apply.
  3. Select Advanced Configuration Mode in the upper right corner of the screen.
  4. Under the Multicast menu, select Properties. Enable Bridge Multicast Filtering. For each VLAN, select IP Group Address" as the Forwarding Method. Click Apply.
  5. Under the Multicast menu, select IPv4 Multicast Configuration > IGMP Snooping menu and enable Snooping. Click Apply.
  6. Edit each VLAN in the IGMP Snooping Menu as follows:
    1. Enable Snooping Status & Querier Status.
    2. Set Query Interval to 30 seconds.
    3. Select IGMPv2 as the Querier version.
    4. Select Auto for Querier Source IP Address. Click Apply.
  7. Under the Multicast menu, select IPv4 Multicast Configuration > IGMP VLAN Settings and configure each VLAN as follows. Click Apply for each VLAN.
  8. Under the Multicast menu, select Multicast Router Port and set all ports to None. This will cause the switch to Auto-Detect a Multicast Router Port if needed. Click Apply if needed.
  9. Under the Multicast menu, select Forward and set all ports to None.  This will prevent multicast from Flooding all ports. Click Apply if needed.
  10. Under the Multicast menu, select Unregistered Multicast and set all ports connected to Shure equipment and your Dante Controller PC to Forward. Failure to do this may cause Dante Controller and Shure's tools to not discover any devices. Click Apply if needed.
  11. Under the Quality of Service, menu, select QoS Properties. Set mode to Basic. Click Apply if needed.
  12. Under the Quality of Service, menu, select QoS Basic Mode > Global Settings. Set Trust Mode to DSCP. Click Apply if needed.
  13. Under the Quality of Service, menu, select DSCP to Queue. Set Trust Mode to DSCP. Configure the table to look like the screenshot below with DSCP 56 set to Queue 4, DSCP46 set to Queue 3, DSCP34 set to Queue 2, and all other DSCP values set to Queue 1. PRO TIP: Tab between each field and use the number keys to set the values, it is much quicker than using the mouse. Click Apply.
  14. The switch is now configured. Save the settings and create a backup.

Verifying Your Work

  1. Connect all of your Shure devices to the network switch, and if necessary, assign them a Static IP address.
  2. Open Dante Controller and ensure all devices appear under the Device Info tab.
  3. Verify that only one device is the Master on the Clock Status tab. All other devices should say Slave. If you are using AES67, we generally recommend that the same device serve as both the Dante and AES67 master.
  4. Open Shure Update Utility, and configure it to use your Ethernet adaptor. Verify that all devices appear in the list, and are on the latest firmware.
    1. If devices do not appear, please troubleshoot according to these directions: Update Utility Stuck in "Discovering" or device not showing up
  5. Route your audio as desired, and ensure it is working correctly.
