Configuration Commands

RADIUS protocol is configured scheme by scheme. Every RADIUS scheme must at
least specify IP address and UDP port number of RADIUS
authentication/authorization/accounting server and the parameters necessary for the
RADIUS client (a router) to interact with the servers. You must first create a RADIUS
scheme and enter its view before you can perform RADIUS protocol configurations.
A RADIUS scheme can be referenced by several ISP domains at the same time.
The undo radius scheme command can be used to delete any RADIUS scheme
except for the default one. Note that a RADIUS scheme currently being used by any
online users cannot be removed.

1.2.15 radius nas-ip
Syntax
radius nas-ip ip-address
undo radius nas-ip
View
System view
Parameter
ip-address: Specifies a source IP address.
Description
Use the radius nas-ip command to specify the source address of the RADIUS packet
sent from NAS.
Use the undo radius nas-ip command to restore the default setting..
By specifying the source address of the RADIUS packet, you can avoid unreachable
packets as returned from the server upon interface failure. The source address is
normally recommended to be a loopback interface address..
By default, the source address is not specified, that is, the address of the interface
sending the packet serves as the source address.
