Thanks, Chuck!
This works for defining the port but does not work for the host.
<Member className="org.apache.catalina.tribes.membership.StaticMember"
port="4000" host="${tomcat.member:-localhost}"/>
<Member className="org.apache.catalina.tribes.membership.StaticMember"
port="4000" host="${tomcat.member:-127.0.0.1}"/>
Using either of the above throws the following error,

What is the value of the system property "tomcat.member"?

Yes, I agree. Can you run under a debugger and observe the value being
set? Or recompile it with a log statement? I don't see much logging in
that class, and I'm not familiar enough with the clustering code to know
where best to enable logging to see the effective configuration.
