To enable or unlock the linuxadmin user, enter CONFIGURATION mode and execute the command no system-user

RADIUS authentication
To configure a RADIUS server for authentication, enter the server IP address or host name, and the key used to authenticate
the OS10 switch on a RADIUS host. You can enter the authentication key in plain text or encrypted format. You can change the
User Datagram Protocol (UDP) port number on the server.
● Configure a RADIUS authentication server in CONFIGURATION mode. By default, a RADIUS server uses UDP port 1812.
radius-server host {hostname | ip-address} key {0 authentication-key | 9
authentication-key | authentication-key} [auth-port port-number]
Re-enter the radius-server host command multiple times to configure more than one RADIUS server. If you configure
multiple RADIUS servers, OS10 attempts to connect in the order you configured them. An OS10 switch connects with the
configured RADIUS servers one at a time, until a RADIUS server responds with an accept or reject response. The switch tries to
connect with a server for the configured number of retransmit retries and timeout period.
Configure global settings for the timeout and retransmit attempts allowed on RADIUS servers. By default, OS10 supports three
RADIUS authentication attempts and times out after five seconds. no source interface is configured. The default VRF instance is
used to contact RADIUS servers.
NOTE:
You cannot configure both a non-default VRF instance and a source interface at the same time for RADIUS
authentication.
● Configure the number of times OS10 retransmits a RADIUS authentication request in CONFIGURATION mode, from 0 to 100
retries; the default is 3.

● 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.

● (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.
NOTE: If you configure a source interface which has no IP address, the IP address of the management interface is used.

● (Optional) By default, the switch uses the default VRF instance to communicate with RADIUS servers. You can optionally
configure a non-default or the management VRF instance for RADIUS authentication in CONFIGURATION mode.
