role, and many users can have the same role. A user role authenticates and authorizes a user at login, and places you in EXEC mode (see CLI basics). OS10 supports four pre-defined roles: sysadmin, secadmin, netadmin, and netoperator. Each user role assigns permissions that determine the commands a user can enter, and the actions a user can perform. RBAC provides an easy and efficient way to administer user rights. If a user's role matches one of the allowed user roles for a command, command authorization is granted. The OS10 RBAC model provides separation of duty as well as greater security. It places some limitations on each role's permissions to allow you to partition tasks. For greater security, only some user roles can view events, audits, and security system logs. Assign user role To limit OS10 system access, assign a role when you configure each user. • Enter a user name, password, and role in CONFIGURATION mode. username username password password role role - username username - Enter a text string (up to 32 alphanumeric characters; 1 character minimum). - password password - Enter a text string (up to 32 alphanumeric characters; 9 characters minimum). - role role - Enter a user role: ◦ sysadmin - Full access to all commands in the system, exclusive access to commands that manipulate the file system, and access to the system shell. A system administrator can create user IDs and user roles. ◦ secadmin - Full access to configuration commands that set security policy and system access, such as password strength, AAA authorization, and cryptographic keys. A security administrator can display security information, such as cryptographic keys, login statistics, and log information. ◦ netadmin - Full access to configuration commands that manage traffic flowing through the switch, such as routes, interfaces, and ACLs. A network administrator cannot access configuration commands for security features or view security information. ◦ netoperator - Access to EXEC mode to view the current configuration. A network operator cannot modify any configuration setting on a switch.

You can enter the authentication key in plain text or encrypted format. You can change the 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 520 System management

role, and many users can have the same role. A user role authenticates and authorizes a user at login, and places you in EXEC mode (see
CLI basics
).
OS10 supports four
pre-defined
roles: sysadmin, secadmin, netadmin, and netoperator. Each user role assigns permissions that determine
the commands a user can enter, and the actions a user can perform. RBAC provides an easy and
efficient
way to administer user rights. If a
user’s role matches one of the allowed user roles for a command, command authorization is granted.
The OS10 RBAC model provides separation of duty as well as greater security. It places some limitations on each role’s permissions to allow
you to partition tasks. For greater security, only some user roles can view events, audits, and security system logs.
Assign user role
To limit OS10 system access, assign a role when you
configure
each user.
Enter a user name, password, and role in CONFIGURATION mode.

sysadmin
— Full access to all commands in the system, exclusive access to commands that manipulate the
file
system, and
access to the system shell. A system administrator can create user IDs and user roles.
secadmin
— Full access to
configuration
commands that set security policy and system access, such as password strength,
AAA authorization, and cryptographic keys. A security administrator can display security information, such as cryptographic
keys, login statistics, and log information.
netadmin
— Full access to
configuration
commands that manage
traffic
flowing
through the switch, such as routes,
interfaces, and ACLs. A network administrator cannot access
configuration
commands for security features or view security
information.
netoperator
— Access to EXEC mode to view the current
configuration.
A network operator cannot modify any
configuration
setting on a switch.

To
configure
a RADIUS server for authentication, enter the server's 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 UDP port number on
the server.
Configure
a RADIUS authentication server in CONFIGURATION mode. By default, a RADIUS server uses UDP port 1812.

more than one RADIUS server. If you

them. An OS10 switch connects with the
