Parameter 
ip-address: Source IP address, an IP address of this device. This address can be 
neither an all zero address nor a Class-D address. 
Description 
Use the radius nas-ip command to set the source IP address used by the switch to 
send RADIUS packets. 
Use the undo radius nas-ip command to restore the default setting. 
By default, no source IP address is specified, and the IP address of the outbound 
interface is used as the source IP address of the packet. 
 
  Note: 
The nas-ip command in RADIUS scheme view has the same function as the radius 
nas-ip command in system view; and the priority of configuration in RADIUS scheme 
view is higher than in system view. 
 
Note that: 
z  You can specify the source IP address used to send RADIUS packet to prevent 
the unreachability of the packets returned from the server due to physical 
interface trouble. It is recommended to use the loopback interface address as the 
source IP address. 
z  You can specify only one source IP address by using this command. When you 
use this command again, the newly specified source IP address will overwrite the 
old one. 
Related command: nas-ip.
