Specifying the RADIUS authentication servers
A RADIUS authentication server completes authentication and authorization together, because
authorization information is piggybacked in authentication responses sent to RADIUS clients.
You can specify one primary authentication server and up to 16 secondary authentication servers for a
RADIUS scheme. When the primary server is not available, the device tries to communicate with the
secondary servers in the order they are configured, and communicates with the first secondary server in
active
state. If redundancy is not needed, specify only the primary server. A RADIUS authentication
server can function as the primary authentication server for one scheme and a secondary authentication
server for another scheme at the same time.
To specify RADIUS authentication servers for a RADIUS scheme:

Specify the primary RADIUS
authentication server:
primary authentication
{
ipv4-address
|
ipv6
ipv6-address
}
[
port-number
|
key
{
cipher
|
simple
}
string
|
vpn-instance
vpn-instance-name
] *
•
Specify a secondary RADIUS
authentication server:
secondary
authentication
{
ipv4-address
|
ipv6
ipv6-address
}
[
port-number
|
key
{
cipher
|
simple
}
string
|
vpn-instance
vpn-instance-name
] *
Configure at least one command.
By default, no authentication server
is specified.
Two authentication servers in a
scheme, primary or secondary,
cannot have the same combination
of IP address, port number, and
VPN.
Specifying the RADIUS accounting servers and the relevant parameters
You can specify one primary accounting server and up to 16 secondary accounting servers for a RADIUS
scheme. When the primary server is not available, the device tries to communicate with the secondary
servers in the order they are configured, and communicates with the first secondary server in
active
state.
When redundancy is not required, specify only the primary server. A RADIUS accounting server can
function as the primary accounting server for one scheme and a secondary accounting server for
another scheme at the same time.
When the device receives a connection teardown request from a host or a connection teardown
command from an administrator, it sends a stop-accounting request to the accounting server. When the
maximum number of real-time accounting attempts is reached, the device disconnects users who have no
accounting responses.
RADIUS does not support accounting for FTP users.
