ip radius source-interface

Configures an interface as the source IP address from which the RADIUS client sends RADIUS requests or receives responses.
Syntax
ip radius source-interface { ethernet stack-id/slot/port | loopback number | management number | ve number }
no ip radius source-interface { ethernet stack-id/slot/port | loopback number | management number | ve number }
Command Default

When a management VRF is configured, the RADIUS client sends RADIUS requests and receives responses only through ports belonging to the management VRF and through the out-of-band management port.

Parameters
ethernet stack-id/slot/port

Specifies the Ethernet interface address used for setting the source IP address.

loopback number
Specifies the loopback interface address used for setting the source IP address.
management number
Specifies the management interface address used for setting the source IP address.
ve number
Specifies the Virtual Ethernet interface address used for setting the source IP address.
Modes

Global configuration mode

Usage Guidelines

When a source interface is configured, management applications use the lowest configured IP address of the specified interface as the source IP address in all the outgoing packets. If the configured interface is not part of the management VRF, the response packet does not reach the destination.

The RADIUS source interface configuration command ip radius source-interface should be compatible with the management VRF configuration.

Note: Any change in the management VRF configuration takes effect immediately for the RADIUS client.

The no form of the command removes the configured interface as the source IP address for the RADIUS client.

Examples

The following example configures an Ethernet interface as the source IP address for the RADIUS client.

device(config)# ip radius source-interface ethernet 1/1/1

The following example configures a loopback interface as the source IP address for the RADIUS client.

device(config)# ip radius source-interface loopback 1
