Disabling or locking the linuxadmin user:
To disable or lock the linuxadmin user, enter CONFIGURATION mode and execute the command system-user linuxadmin
disable.
OS10(config)# system-user linuxadmin disable
OS10(config)#
Enabling or unlocking the linuxadmin user:
To enable or unlock the linuxadmin user, enter CONFIGURATION mode and execute the command no system-user linuxadmin

OS10(config)# no system-user linuxadmin disable
OS10(config)#
RADIUS authentication
To congure 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.
• Congure 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 congure more than one RADIUS server. If you congure multiple
RADIUS servers, OS10 attempts to connect in the order you congured them. An OS10 switch connects with the congured 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
congured number of retransmit retries and timeout period.
Congure global settings for the timeout and retransmit attempts allowed on RADIUS servers. By default, OS10 supports three RADIUS
authentication attempts and times out after ve seconds. no source interface is congured. The default VRF instance is used to contact
RADIUS servers.
NOTE
: You cannot congure both a non-default VRF instance and a source interface at the same time for RADIUS
authentication.
• Congure the number of times OS10 retransmits a RADIUS authentication request in CONFIGURATION mode, from 0 to 100 retries;
the default is 3.

• Congure 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 congured. OS10 selects the source IP address of any interface from which
a packet is sent to a RADIUS server.
NOTE
: If you congure a source interface which has no IP address, the IP address of the management interface is
used.
ip radius source-interface interface
• (Optional) By default, the switch uses the default VRF instance to communicate with RADIUS servers. You can optionally congure a
non-default or the management VRF instance for RADIUS authentication in CONFIGURATION mode.
