Bonjour Gateway on 7.4

Mopad1010 — Sun, 04 Jul 2021 07:01:33 GMT

I work in a k-12 school district and we have around 100 ipads, 10 apple tvs, a half dozen air print capable printers, and about 300 mac computers.

I'm running vwlc 7.4 with fifty 3602i ap's.

I'm unable to get the mdns / bonjour gatway to work. I have it enabled it, added the different services I want, and enabled the profiles on the wlans.

I have followed the guide @ http://www.cisco.com/en/US/docs/wireless/technology/bonjour/Bonjour_DG_Guide.pdf which seems pretty simple.

Is there anything I need to do to my switches? Do I need to enable multicast or pim?

I have the ipads and the apple tvs on the same subnet/vlan. It seems to flap. Sometimes when I try to airplay from a ipad, the apple tvs will show up right away. The next time they won't (this is most of the time).

I also have a imac that has apple remote desktop installed. If the imac is on the wired network, it can pull up all the other computers that are on the wired network with it, but no wireless clients. When I put the imac onto the wireless network along with the other wirless mac's, apple remote desktop does not pull up any clients from either the wired or wireless.

Non of the ipads can see any of the air print pinters on my wired network.

Is there something more I need to do on my switching, or shouldn't the bounjour gateway take care of this?

You do need to enable multicast on the switches in order for mDNS to work properly. Take a look at this support doc as it will explain in more detail.

Bonjour Gateway on 7.4

#Display the Multicast config, try with Multicast mode Unicast.

#mDNS does two things

a) Eliminate Multicast Routing being enabled on Wired side when WLC and AP on different subnet to avoid Multicast capwap routing.

b) Voluntarily display the Bonjour services on other wired/wireless vlan based on the configuration.

#Multicast mode Multicast is for wireless Multicast traffic efficiency on capwap only(btw WLC to AP) and it doesn't affect the actual Multicast traffic and with mDNS, M-M mode is optional and can also say it is of not much use because only Bonjour Discovery is Multicast and real data connection is P2P tcp unicast.
