TCP and UDP Ports
The adaptive security appliance listens for RADIUS on ports 1645 and 1646. If your RADIUS server
•
uses the standard ports 1812 and 1813, you can configure the adaptive security appliance to listen
to those ports using the authentication-port and accounting-port commands.
To assign a port for DNS access, use the domain literal value, not dns. If you use dns, the adaptive
•
security appliance assumes you meant to use the dnsix literal value.
Port numbers can be viewed online at the IANA website:
