Security Commands 1040
Example
The following example configures the source IP address used for
communication with RADIUS servers to 10.1.1.1.
console(config)#radius server source-ip 10.1.1.1
radius server source-interface
Use the radius server source-interface command to select the interface from
which to use the IP address in the source IP address field of transmitted
RADIUS packets. Use the no form of the command to revert to the default IP
address.
Syntax
radius server source-interface {loopback loopback-id | vlan vlan-id}
no radius server source-interface
• loopback-id — A loopback interface identifier.
• vlan-id—A VLAN identifier.
Default Configuration
By default, the switch uses the assigned switch IP address as the source IP
address for RADIUS packets. This is either the IP address assigned to the
VLAN from which the RADIUS packet originates or the out-of-band interface
IP address.
Command Mode
Global Configuration
User Guidelines
The source IP address of RADIUS packets sent to a server should match the
NAS IP address configured on the RADIUS server. A mismatch may lead to a
RADIUS packet timeout.
Loopback interfaces are not supported on the Dell EMC N1100-ON Series
switches.
