Network Switch = No Music

[TheOldPresbyope]

The switch is blocking multicast DNS (mDNS) packets.

mDNS is the discovery protocol used to resolve .local domain. You will experience a lot of breakage without mDNS.

Thank Tim.

I'll do some research to find out if the switch can be configured to handle that.

This would suggest you have an active, e.g., managed, switch. Pretty fancy. 

What model of each of your networking gear do you have? Virgin Hubs, Netgear WiFi routers, and Cisco switches come in various flavors.

Hi Kent,

Virgin Hub 3.0
Netgear Nighthawk X6

Glad you are impressed. As the kids tell me about my golfing and fishing. All the gear and no idea.

Damn those pesky kids.

Wow. That switch exceeds anything I ever had in my hands at work. This is not what Harry Homeowner finds at the local Best Buy.

The Cisco documentation is impenetrable so I went to Mama Google and she turned up this: Multicast Does Not Work in the Same VLAN in Catalyst Switches. The introduction says

This document discusses a common problem that occurs when you deploy the multicast application for the first time on a Cisco Catalyst switch network and the multicast fails to work. In addition, some servers/applications that use multicast packets for the cluster/high-availability operation can fail to work if you do not configure the switches appropriately. The document covers this issue as well.

Hope it helps. Despite what the techie posts here might make you think, we all just want to enjoy the music!

Regards,
Kent

PS - My personal experience is that my grandkids are more impressed by how much I know than my kids are
