HP 6125G Configuration Manual page 36

If one server is in active state and all the others are in blocked state, the switch only tries to
•
communicate with the server in active state, even if the server is unavailable.
After receiving an authentication/accounting response from a server, the switch changes the status
•
of the server identified by the source IP address of the response to active if the current status of the
server is blocked.
The device does not change the status of an unreachable authentication or accounting server if the server
quiet timer is set to 0. Instead, the device keeps the server status as active and sends authentication or
accounting packets to another server in active state, so subsequent authentication or accounting packets
can still be sent to that server. For more information about the server quiet timer, see
controlling communication with HWTACACS
By default, the switch sets the status of all RADIUS servers to active. In cases such as a server failure, you
can change the status of the server to blocked to avoid communication with the server.
To set the status of RADIUS servers in a RADIUS scheme:
Step
1. Enter system view.
2. Enter RADIUS scheme
view.
3. Set the RADIUS server
status.
NOTE:
• The server status set by the state command cannot be saved to the configuration file. After the switch
restarts, the status of each server is restored to active.
To display the states of the servers, use the display radius scheme command.

Specifying the source IP address for outgoing RADIUS packets
The source IP address of RADIUS packets that a NAS sends must match the IP address of the NAS
configured on the RADIUS server. A RADIUS server identifies a NAS by its IP address. Upon receiving a
RADIUS packet, a RADIUS server checks whether the source IP address of the packet is the IP address of
any managed NAS. If yes, the server processes the packet. If not, the server drops the packet.
Usually, the source address of outgoing RADIUS packets can be the IP address of the NAS's any
interface that can communicate with the RADIUS server. In some special scenarios, however, you must
change the source IP address. For example, if a Network Address Translation (NAT) device is present
