Once we have identified that switch, please note its assigned static IP address as we will be using this IP address to manually configure every switch on the network. The simplest solution is to select the network switch that will result in the least “hops” between multicast equipment communicating.īasically, we want to select the network switch that is the MOST central to all other switches and the multicast equipment being utilized on them. Which network switch is going to host the mDNS entries? With the steps provided below we will log into each switch on the network and manually configure the switches to communicate properly.Ĭonfiguring “Logical Querier” and “Query Interval” for each switchīefore beginning, there is an important decision that must be made… If you have a network with more than one (1) switch these settings aren’t enough. You’ve setup EVERYTHING Ubiquiti allows for configuration via the WebUI for multicast traffic and mDNS discovery. Once logged in you, should see a “Dashboard” displayed with current network statistics and graphs similar to what is shown below. Login to the web interface of your Ubiquiti network using the “Unifi Web Login” or by directly logging in to the IP of your controller / cloud key.

(1) UAP-AC-PRO-US “802.11ac Dual Radio Pro Access Point”.(1) UC-CK “Unifi Cloud Key” or “Controller”.Ubiquiti Equipment used for this documentation Also of note is that not all wireless access points are capable of handling multicast traffic please refer to manufacturer documentation. Multicast traffic via your WiFi network is a decision that should not be taken lightly as it is very easy to overload a wireless access point with multicast traffic. The next step is enabling IGMP and possibly, depending on your exact requirements, enabling or disabling multicast traffic via wireless access points. If the tables are not being held properly in one location the discovery will be intermittent at best. These tables are what your network will reference when it tries to route traffic to your device. When the IGMP snooping querier is enabled, it periodically sends queries that trigger IGMP response messages from hosts that are requesting to receive IP multicast traffic. When you have more than one (1) network switch being utilized in a situation with equipment and applications that utilize mDNS for discovery, the switches need to be told which switch will be the “holder” of mDNS discovery tables. When connecting to a multicast source, your network slows to an unusable speed.When connecting to a multicast source, your network crashes.When connecting to a multicast source and have a successful connection, but receive no content.When connecting to a multicast source, your video appears to “smear” or “bleed”.When you utilize a discovery or configuration tool, it randomly finds devices which also disappear randomly.When you utilize a discovery or configuration tool, it is unable to locate your device connected to the same network.
We take no responsibility for any issues or losses that may arise from following the instructions presented in this document and implementation of the instructions is at your own risk. Once all changes have been made to make your network fully operational for multicast and mDNS, you must be aware that the mDNS routing is not a “persistent” change and thus will be overwritten with any power cycle or “provisioning” of the network switches, meaning these steps will need to be taken again. Thus, it is highly recommended to use the same managed networking equipment from “top to bottom” to prevent frustrations caused by incompatibilities. If any part of the network is NOT managed, or manually configured to work in unison with the rest of the network, failure will result because of incompatibilities in communication between the networking equipment. We will assume that you are using an entirely managed network, and specifically for this document a Ubiquiti network (Router, Switches and possibly Wireless Access Points) that is already operational with static IPs assigned for all Ubiquiti hardware.

We will cover enabling IGMP and mDNS, then how to setup routing to allow mDNS and multicast traffic to flow properly. While the instructions provided below are specific to Ubiquiti products at this current date, the general concepts should apply to most managed networks. In this document, we will cover the easiest way to properly configure your Ubiquiti network for use with mDNS and multicast devices and have a basic understanding of the changes that have been made.
