Disable the network discovery port

Applies to: Pearl-2, Pearl Mini, Pearl Nexus, Pearl Nano

You can disable the network discovery port on the device using the Admin panel so that services can no longer discover the device using multicast DNS (mDNS). The network discovery port is port 5557 and is enabled by default.

Important considerations

• You cannot connect to the Admin panel using a DNS-based service discovery if you disable the network discovery port.

• On Pearl-2, Pearl Mini, and Pearl Nexus, the network discovery port must be enabled to use the NDI (NDI|HX) feature.

Disable the network discovery port using the Admin panel

• Log in to the Admin panel as admin.

• From the Configuration menu, select Network and then the Interfaces tab. The Network Interfaces page opens.

• Uncheck Make this device discoverable on the network as <uniqueID.local>, then click Apply.

Device differences

• Pearl Nano: Has no NDI/NDI|HX feature, so the "must be enabled to use NDI" consideration does not apply. Navigation is simpler: From the Configuration menu, select Network. The Network configuration page opens (no separate Interfaces tab).
