n
is the number of AAA servers to which accounting data will be sent, and must be an integer from 2 through
128.
first-server
Specifies that the context must send accounting data to the RADIUS accounting server with the highest
configured priority. In the event that this server becomes unreachable, accounting data is sent to the server
with the next-highest configured priority. This is the default algorithm.
configured priority. In the event that this server becomes unreachable, accounting data is sent to the server
with the next-highest configured priority. This is the default algorithm.
round-robin
Specifies that the context must load balance sending accounting data among all of the defined RADIUS
accounting servers. Accounting data is sent in a circular queue fashion on a per Session Manager task basis,
where data is sent to the next available server and restarts at the beginning of the list of configured servers.
The order of the list is based upon the configured relative priority of the servers.
In releases to prior to 17, for subscribers with IMSI containing hexadecimal characters the round robin
algorithm fails causing the messages to be forwarded to a single RADIUS server all the time. This algorithm
works only for decimal based IMSI addresses.
