Configure the timeout period used to wait for an authentication response from a RADIUS server in CONFIGURATION mode,
from 0 to 1000 seconds; the default is 5.
radius-server timeout seconds
(Optional) Specify an interface whose IP address is used as the source IP address for user authentication with RADIUS
servers in CONFIGURATION mode. By default, no source interface is configured. OS10 selects the source IP address of any
interface from which a packet is sent to a RADIUS server.
An interface may have two IPv4 addresses and multiple IPv6 addresses. The selected OS10 source interface matches the
version of the RADIUS server IP address: IPv4 or IPv6.
For an IPv4 RADIUS server, the primary IPv4 address is used.
For an IPv6 server, any of the global IPv6 addresses that are configured on the interface are used.
If no address of the same IP version as the RADIUS server is configured, RADIUS authentication is performed with no
source interface, using the IP address of the management interface. The management IP address serves as the RADIUS
network access server (NAS) IP address on the switch.
ip radius source-interface interface
On the RADIUS server, you must update the configured IP routes using the Linux command line so that the source interface
routes match the NAS IP route.
If OS10 uses a RADIUS server VRF instance, a RADIUS server source interface is not supported and cannot be configured.
(Optional) When you use management VRF for RADIUS authentication, configure the IP address of the network access
server (NAS) using the radius-server nas-ip-address command.
radius-server nas-ip-address ipv4-address
(Optional) By default, the switch uses the default VRF instance to communicate with RADIUS servers. You can optionally
configure a nondefault or the management VRF instance for RADIUS authentication in CONFIGURATION mode.
