Gateway Devices

The mDNS Gateway Devices Screen displays all configured mDNS Gateway Switches and is used to create, edit, and delete, mDNS Gateway Switches. An mDNS Gateway Switch replaces the Wireless Controller used in Legacy mDNS, and can be used if there are Stellar Access Points (APs) in the network. A Gateway mDNS Switch floods mDNS messages over designated VLANs. Wireless clients connected to APs request the mDNS service offered. The mDNS message from the Bonjour capable wired service device is tagged with a VLAN and relayed to the Gateway Switch. The Gateway Switch then relays the mDNS messages received to the APs over the designated Gateway VLANs.

The mDNS Gateway Model is a simpler configuration that the Responder Model. When you use the Gateway Model, you configure a switch as an mDNS Gateway and specify a list of VLANs that will be flooded with mDNS messages. The Responder Model uses Responder Switches to relay mDNS messages and enables the discovery of services across VLANs; and also enable you to configure and apply rules and policies to the data traffic.

Note: mDNS Gateway is supported on OS6450 Switches running AOS 6.7.2.R02 or higher; and OS6860E, OS6865, and OS6900 Switches running 8.4.1.R02 or higher. A switch can be configured as either a Gateway Device or a Responder Device. It cannot be configured for both.

Creating an mDNS Gateway

Click the Add icon to go to the Add Gateway Device Configuration Screen and complete the fields as described below. When you are done, click on the Create button.

• Device Friendly Name - Click on the ADD button and use the switch picker or Topology application to select the switch you want to configure as a gateway.
• mDNS Admin Status - The mDNS administrative status (Enabled/Disabled). mDNS relay enables the OmniSwitch to allow Apple devices to discover services with minimal configuration by the administrator.
• SSDP Admin Status - The SSDP administrative status (Enabled/Disabled). SSDP relay enables the OmniSwitch to allow non-Apple devices to discover services with minimal configuration by the administrator.
• VLANs List - Select VLAN(s) from the drop-down list. This is the list of VLANs on the Gateway Switch where the mDNS server/client traffic from the edge devices is expected to arrive. mDNS packets are forwarded to all VLANs specified in this list. Specify the mDNS VLAN(s) that are used in the network. However, if the specified VLAN(s) do not exist on the Gateway Switch, you must create them in the VLAN application later for the configuration to work in the network.

Editing an mDNS Gateway

Select the switch in the Gateway Devices Table and click on the Edit icon to bring up the Add Gateway Device Configuration Screen. Edit the allowable fields as described above and click on the Apply button.

Deleting an mDNS Gateway

Select the switch in the Gateway Devices Table, click on the Delete icon, then click OK at the confirmation prompt.

Gateway Devices Table

The Gateway Devices Table displays The fields are defined below.

• Device Friendly Name - The switch IP address.
• mDNS Admin Status - The mDNS administrative status (Enabled/Disabled).
• mDNS Operational Status - The mDNS operational status. (Up/Down).
• SSDP Admin Status - The SSDP administrative status (Enabled/Disabled).
• SSDP Operational Status - The SSDP operational status (Up/Down).
• VLANs List - The list of device VLANs configured for mDNS. mDNS packets are flooded on all specified VLANs.
