Re: Wireless mDNS Bridging CLI command

Was there ever a real response / solution to the original question ?

Because I think I might have the same problem.
9800 -> Configuration -> Services -> Multicast - Wireless mDNS Bridging (enable or disable)
What is the equivalent CLI command ?
Our scenario is that it seems that Catalyst Center disables this single feature, on provision, and we would "just" create a CLI template that enables it. But we simply cannot find the added command in the configuration. Also in a "diff" of startup / running.
Documentation does not seem to cover this, only that you can see it enabled through show commands, but not "the" command to enable it.
Cheers - Thomas

To Enable:
wireless multicast link-local


To Disable:
no wireless multicast link-local

Beginning with Cisco IOS-XE 17.6.1 and later, when you enable global wireless multicast (wireless multicast), link-local multicast bridging (which handles mDNS) is enabled by default.

 

To override what Catalyst Center is pushing and force-enable the feature, you can add the following block to your CLI template:

wireless multicast
wireless multicast link-local

I am not a Cisco employee. My suggestions are based on documentation of Meraki best practices and day-to-day experience.

Please, if this post was useful, leave your kudos and mark it as solved.
