Hi Andy,
The alias port can be used if you want to LTM to monitor a port that is different than the one the pool member is defined on.
One example is if the pool members are defined on port 0 (any) and you want to check if the pool member answers on port 443.
Another example is if you want to check both port 80 and port 443 and require both services to be up in order to consider the server up in both an HTTP and HTTPS pool. You can also apply monitors to nodes to accomplish this this. As a node by definition is just an IP address, you need to specify which port LTM should check the node on.
For standard pool member monitors, you can leave the alias address and port set to * and the monitoring daemon, bigd, will use the pool member's IP and port for the monitor requests.
