Protocols and Applications
lists the protocol literal values and port numbers; either can be entered in ASA commands.
Protocol numbers can be viewed online at the IANA website:
TCP and UDP Ports
lists the literal values and port numbers; either can be entered in ASA commands. See the
following caveats:
•
The ASA 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 ASA listens for RADIUS on ports 1645 and 1646. If your RADIUS server uses the standard
ports 1812 and 1813, you can configure the ASA to listen to those ports using the
authentication-port and accounting-port commands.
