Resolution:
Yes, you can do that.  For example, assume the machine has two interface card with the IP address of ip1 and ip2 and you want to run EMS using the same port number n.

We can create two tibemsd.conf file and define listen parameter in one as tcp://&ltip1>:n and in another as tcp://&ltip2>:n
Using the above configuration, you can start two EMS servers.

In the same way, the single instace of EMS server can also listen on two different interface card using the same
port number n. In that case, you need to define the listen parameter twice with different IP address and the same
port number.
