Ports
During the EM12c installation, you are prompted to supply a list of ports for entities to communicate on. A default list
is provided on the Port Configuration Details page, shown in Figure 1-8 . The page displays a Recommended Port Range
column. The first port number listed in this column is the default port. If for any reason the default port is already
used when you are doing an installation, the next port number in the Recommended Port Range will be used. Post
installation, you can also find the port numbers that were used in the staticports.ini file, located on the OMS host.

Firewalls
In many cases, a business will require firewalls to be used to control both outgoing and incoming network
traffic. This typically involves restricting either the availability of ports or the type of traffic that can pass through
a particular port. Because this restriction can be difficult to set up, it is usually recommended that firewall
configuration and enablement are left until after you have deployed your Enterprise Manager configuration.
However, if the firewalls are already in place, you should open the communication ports you are planning to use
until the installation is complete.
