The FWSM uses port 1521 for SQL*Net. This is the default port used by Oracle for SQL*Net. This
value, however, does not agree with IANA port assignments.
The FWSM listens for RADIUS on ports 1645 and 1646. If your RADIUS server uses the standard
ports 1812 and 1813, you can configure the FWSM to listen to those ports using the aaa-server,
radius-authport, and aaa-server radius-acctport commands.
To assign a port for DNS access, use domain, not dns. The dns keyword translates into the port
value for dnsix.
