mDNS between wired and wireless

    Hi all, I have a 7030 wireless controller and Aruba 3810 and 2903 switch infrastructure. I have enabled Airgroup and ticked drop broadcast and unknown multicast. I have configured 3 SSIDs, 1 dot1x, the others PSK, one of the PSK's (VLAN 20)  has AppleTV and Chromecast devices. As it is dot1x devices can connect and play/cast to the devices on the PSK SSID as required. Problem is wired devices on the same VLAN (10) as the authenticated dot1x devices cannot. Also need a server on another VLAN (VLAN 40) which is trunked to the 7030 and uses bonjour (Filemaker Pro) is not seen even if I add it manually, via the MAC address. If we run AirParrot on a wired device on VLAN (10) the 7030 does not see any mDNS from it and it can't see any devices. Do I need to configure some sort of mDNS gateway configured on the 3810 which is the core switch? I thought if there is a trunk to the wireless controller with all the VLANs that require mDNS the controller would control it all? What have I missed?

    Hey Wiggs,

    Were you able to resolve this issue? We are seeing similar behavior. Thanks!

    Any updates on this? We just updated to OS 8.7 and wireless users can't see wired MDNS servers even on the same VLAN.

    Thanks Wiggs. We will look into that as well.

    Same problem here, need to have eXxothermic Listen Everywhere to works between wireless vlan also. Have enabled msns and register its service on airgroup and mdn profile but not working.

    Hi Brad, we had a job logged with Aruba Support who worked through the config and couldn't resolve completely. So we can see devices between wired and wireless but not between wireless vlans. The advice I received from a Aruba tech in country said we need to make the physical port untrusted. " I have my wired ports as untrusted and default role as authenticated to get visibility from the wired side."

    I haven't been able to get back to try that but it is on my list. When I do I will give an update either way.
