Configuring RADIUS security

commands)
• 5 – Records commands available at the Read Only level (read-only commands)
Configuring RADIUS accounting for system events
You can configure RADIUS accounting to record when system events occur on the Brocade Virtual
ADX. System events include rebooting and when changes to the active configuration are made.
The following command causes an Accounting Start packet to be sent to the RADIUS accounting
server when a system event occurs, and a Accounting Stop packet to be sent when the system
event is completed.
Virtual ADX(config)#aaa accounting system default start-stop radius
Syntax: aaa accounting system default start-stop radius | tacacs+ | none
Configuring an interface as the source for all RADIUS packets
You can designate the lowest-numbered IP address configured an Ethernet port, loopback
interface, or virtual interface as the source IP address for all RADIUS packets from the Layer 3
Switch. Identifying a single source IP address for RADIUS packets provides the following benefits:
• If your RADIUS server is configured to accept packets only from specific links or IP addresses,
you can use this feature to simplify configuration of the RADIUS server by configuring the
Brocade Virtual ADX to always send the RADIUS packets from the same link or source address.
• If you specify a loopback interface as the single source for RADIUS packets, RADIUS servers
can receive the packets regardless of the states of individual links. Thus, if a link to the RADIUS
server becomes unavailable but the client or server can be reached through another link, the
client or server still receives the packets, and the packets still have the source IP address of
the loopback interface.
The software contains separate CLI commands for specifying the source interface for Telnet,
TACACS or TACACS+, and RADIUS packets. You can configure a source interface for one or more of
these types of packets.
To specify an Ethernet port or a loopback or virtual interface as the source for all RADIUS packets
from the device, use the following CLI method. The software uses the lowest-numbered IP address
configured on the port or interface as the source IP address for RADIUS packets originated by the
device.
To specify the lowest-numbered IP address configured on a virtual interface as the device’s source
for all RADIUS packets, enter commands such as the following.
Virtual ADX(config)#interface ve 1
Virtual ADX(config-vif-1)#ip address 10.0.0.3/24
Virtual ADX(config-vif-1)#exit
Virtual ADX(config)#ip radius source-interface ve 1
The commands in this example configure virtual interface 1, assign IP address 10.0.0.3/24 to the
interface, then designate the interface as the source for all RADIUS packets from the Layer 3
Switch.
Syntax: ip radius source-interface ethernet portnum | loopback num | ve num
