2.
Enter RADIUS scheme
view.
radius scheme
radius-scheme-name
—
3.
Specify the primary
RADIUS accounting server.
primary accounting
{
ip-address
|
ipv6
ipv6-
address
} [
port-number
|
key
string
|
vpn-
instance
vpn-instance-name
] *
Required.
Configure at least one
command.
No accounting server is
specified by default.
4.
Specify the secondary
RADIUS accounting server.
secondary
accounting
{
ip-address
|
ipv6
ipv6-address
} [
port-number
|
key
string
|
vpn-instance
vpn-instance-name
] *
5.
Set the maximum number
of real-time accounting
attempts.
retry realtime-accounting
retry-times
Optional.
5 by default.
6.
Enable buffering of stop-
accounting requests to
which no responses are
received.
stop-accounting-buffer enable
Optional.
Enabled by default.
7.
Set the maximum number
of stop-accounting
attempts.
retry stop-accounting
retry-times
Optional.
500 by default.
NOTE:
•
The IP addresses of the primary and secondary accounting servers must be different from each other.
Otherwise, the configuration fails.
•
All servers for authentication/authorization and accountings, primary or secondary, must use IP
addresses of the same IP version.
•
If you delete an accounting server that is serving users, the router can no longer send real-time
accounting requests and stop-accounting requests for the users to that server or buffer the stop-
accounting requests.
•
Specify a RADIUS accounting server as the primary accounting server for one scheme and as the
secondary accounting server for another scheme at the same time.
•
RADIUS does not support accounting for FTP users.
Specifying the shared keys for authenticating RADIUS packets
The RADIUS client and RADIUS server use the MD5 algorithm to encrypt packets exchanged between
them and use shared keys to authenticate the packets. They must use the same shared key for the same
type of packets.
A shared key configured in this task is for all servers of the same type (accounting or authentication) in
the scheme. It has a lower priority than a shared key configured individually for a RADIUS server.
