•
When the quiet timer of a server expires or you manually set the server to the active state, the
status of the server changes back to active. The device does not check the server again during
the authentication or accounting process.
•
When you remove a server in use, communication with the server times out. The device looks
for a server in active state by first checking the primary server, and then checking secondary
servers in the order they are configured.
•
When the primary server and secondary servers are all in blocked state, the device tries to
communicate with the primary server.
•
When one or more servers are in active state, the device tries to communicate with these active
servers only, even if the servers are unavailable.
•
When a RADIUS server's status changes automatically, the device changes this server's status
accordingly in all RADIUS schemes in which this server is specified.
•
When a RADIUS server is manually set to blocked, server detection is disabled for the server,
regardless of whether a test profile has been specified for the server. When the RADIUS server
is set to active state, server detection is enabled for the server on which an existing test profile
is specified.
By default, the device sets the status of all RADIUS servers to active. However, in some situations,
you must change the status of a server. For example, if a server fails, you can change the status of
the server to blocked to avoid communication attempts to the server.
When RADIUS server load sharing is enabled, the device distributes the workload over all servers
without considering the primary and secondary server roles. The device checks the weight value and
number of currently served users for each active server, and then determines the most appropriate
server in performance to receive an AAA request.
In RADIUS server load sharing, once the device sends a start-accounting request to a server for a
user, it forwards all subsequent accounting requests of the user to the same server. If the accounting
server is unreachable, the device returns an accounting failure message rather than searching for
another active accounting server.
To set the status of RADIUS servers:
Step
1. Enter system view.
2. Enter RADIUS scheme
view.
3. Set the RADIUS server
status.
Command
system-view
radius scheme radius-scheme-name
•
Set the status of the primary
RADIUS authentication server:
state primary authentication
{ active | block }
•
Set the status of the primary
RADIUS accounting server:
state primary accounting { active
| block }
•
Set the status of a secondary
RADIUS authentication server:
state secondary authentication
[ { host-name | ipv4-address | ipv6
ipv6-address } [ port-number |
vpn-instance vpn-instance-name ]
* ] { active | block }
•
Set the status of a secondary
RADIUS accounting server:
state secondary accounting
[ { host-name | ipv4-address | ipv6
ipv6-address } [ port-number |
vpn-instance vpn-instance-name ]

By default, every server
specified in a RADIUS
scheme is in active state.
The configured server status
cannot be saved to any
configuration file, and can
only be viewed by using the
display radius scheme
command. After the device
restarts, all servers are
restored to the active state.
