Error Message UDP 3343

Hello,
we are in the process of creating a Hyper-V S2D cluster. For this we have two Cisco Catalyst 2960x switches in use.
When checking the configuration before creating the cluster, we get the following error message under "Network":

The network interface "Server 1" and "Server 2" are located in the same cluster network.
However, the address 192.xxx.xxx.1 is not accessible from 192.xxx.xxx.2 using UDP port 3343

on both switches the acl was adjusted with:

permit udp any any
permit udp any host 192.xxx.xxx.1
permit udp any host 192.xxx.xxx.2

all UDP deny rules were removed.

so far all unsuccessful, the message remains the same.

we have also tested it with switches from other providers, the problem does not occur.
However, other switches than CISCO are not an alternative for the customer.


Does anyone else have an idea what the problem could be?

Hi marce1000

how about removing ACL and is that works ?

since its private IP address no need to hide the IP information post complete ACL ? and how you applied on the Interface ?
