RADIUS Accounting
The RADIUS accounting application will try to send all the concerned packets of a subscriber
host to the same server. If that server is down, then the packet is sent to the next server and,
from that moment on, the RADIUS application uses that server to send its packets for that
subscriber host.
RADIUS PE-Discovery
If the first server in the list cannot find a user, the next server in the RADIUS server list is not
queried and access is denied. If multiple RADIUS servers are used, it is assumed they all have
the same user database.
The RADIUS PE-discovery application makes use of a 10 second time period instead of the
generic 30 seconds and uses a fixed consecutive timeout value of 2 (see
Detection on page
As long as the Session-Timeout (attribute in the RADIUS user file) is specified, it is used for
the polling interval. Otherwise, the configured polling interval will be used (60 seconds by
default).
