Switchport requirements for supporting Rubrik boxes

[KMNRuser]

Community,

I have one of my IT peers whom is in the process of implementing Rubrik boxes for Cloud backup at both our Headquarters and at our DR site.

Each box will live in the Servers vlan in each respective site.

We route between those two sites via an MPLS network across our WAN, or we also have a P2P Gig link between those two sites.  

One of the requirements that Rubrik has published to us was to "Confirm multicast DNS & IPv6 are NOT blocked at the switchport level".  Each Rubrik box will plug into a Cisco 9300X on either side.

How can i confirm that either of those are not being block on the switch ports?

Thank you,

  - The 9300 will not block anything because it is only    a switch ; for port settings guidelines have a look at
     https://docs.rubrik.com/en-us/8.1/hw/hw/switch_configuration_examples.html 
                      The cisco nexus part is fairly the same as for ios-xe on the 9300 ,
