default Health check port ranges & how exclude using some port

The default TCP monitor will check the TCP port configured on the pool member. For example, if you have pool member 1.1.1.1:80, TCP monitor will check port 80 on that IP address (1.1.1.1).

If you want to check some other port for the same pool member: 1.1.1.1:80, you would have to change the "Alias Service Port" option within the TCP monitor from "*" to 8080, if you want to monitor port 8080 for the pool member 1.1.1.1:80 instead of default 80.
