We are currently getting traffic from all cluster members in other environments
using .staticmember opposed to multicast can I confirm why this is see below.
What do we need to set here for a clustered pair to make them unique and talk
to eachother only without seeing traffic from other members in Catalina.out
This is how they are currently configured as you can see only difference
between nodes is the receiver and member ips are reversed. Im concerned
uniqueID is the same, do we also need to specify domain?
uniqueID should be unique at least within the subnet, ideally globally.
Yes, you should use a separate domain for each cluster.
Looking at your config:
You are missing the local member definition
https://tomcat.apache.org/tomcat-10.0-doc/config/cluster-interceptor.html#Static_Membership
The deployer should be defined under the cluster, not under an interceptor.

WE have hostname A and B if you could check below:
