Restrictions for Configuring RadSec
Following restrictions apply to the RadSec feature:
RADIUS client uses an ephemeral port as source port, and this source port should not be used for UDP, Datagram Transport Layer Security (DTLS), and Transport Layer Security (TLS) at the same time.
Although there is no configuration restriction, it is recommended to use the same type, either only TLS or only DTLS, for a server under a Authentication, Authorization, and Accounting (AAA) server group.
RadSec is supported on IPv4 connections only.
