Hi all -- I'm hoping I can lean on your collective wisdom with these switches to get MDNS traffic working correctly between wired and wireless clients on these switches. I was one of the early buyers in this thread and have lived without my chromecasts properly working for the last 1.5-2 years but it's finally annoyed me enough to try and fix it.
Summary of the problem:
All within a single VLAN, Chromecasts (actually NVidia ShieldTVs with chromecast built in) connected to wireless can be found and streamed to reliably. Chromecasts that are connected via ethernet into the Aruba switch cannot be seen on the network. I've done a wireshark packet capture on another computer on the network, and it will show me the MDNS traffic coming from the wireless clients, but traffic from the wired clients doesn't seem to pass back out of the switch to other devices on the network. I'm also having problems with other things relying on broadcast traffic between wired / wireless, but I suspect if I solve it for Chromecast, I'll solve it or everything.
I've reset my Aruba switch to factory config, and have only set up 2 VLANs to support my kids network vs. default network. All of the chromecasts are on the default VLAN, so there should be no complexity communicating between VLANs yet. Below is a screenshot of my basic config on the switch. Thank you for taking a look!
Edit to add a bit more info:
I have several Unifi access points that I use to create my wifi networks. Most are connected to the Aruba switch, one is connected to a Unifi managed switch. I also have one Chromecast connected to a wired Unifi managed switch before uplinking to the Aruba switch. This chromecast always works fine,
which points me back to thinking that it must be the config of the Aruba switch that is not passing on the broadcast traffic consistently.
: devices connected via wifi to Unifi APs (which uplink to Aruba) and devices connected via ethernet to Unifi managed switches (uplinked to Aruba) work. Devices hard-wired to Aruba switch are usually not visible to stream to.
I realize this may be confusing, if I can provide more info that makes this easier to troubleshoot, I'd be happy to.
