OK with your advice I tried what I thought would work from example
and doesn't at all. The old example below works but this doesn’t even
detect members.
Below is example to which Im using on both nodes which are remote to
eachother.
<Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster"
channelSendOptions="8" channelStartOptions = "3">
<Manager className="org.apache.catalina.ha.session.DeltaManager"
expireSessionsOnShutdown="false"
notifyListenersOnReplication="true"/>
<Channel
className="org.apache.catalina.tribes.group.GroupChannel">
<Membership
className="org.apache.catalina.tribes.membership.StaticMembershipService">
<Member
className="org.apache.catalina.tribes.membership.StaticMember"
port="4110"
host="local-tomcat"
domain="tomcat-pc2"
uniqueId="{1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,0}" />
<Member
className="org.apache.catalina.tribes.membership.StaticMember"
port="4110"
host="remote-tomcat"
domain="tomcat-pc2"
uniqueId="{0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15}" />
</Membership>
<Receiver
className="org.apache.catalina.tribes.transport.nio.NioReceiver"

port="4110"

maxThreads="6"/>
<Sender

<Transport

</Sender>

</Channel>

We are currently getting traffic from all cluster members in other

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:
