Dell PowerSwitch S4128F-ON OS10 Enterprise Edition User Guide Release 10.4.3.0 - Page 788

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. A maximum of 32 alphanumeric characters; 1 character minimum. - password password - Enter a text string. A maximum of 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.

OS10 provides a set of three commands which allow you to enable, disable or view bootloader protection information. This feature is available only for the sysadmin and secadmin roles. WARNING: When you enable this feature ensure to keep a copy of a configured username and password, as you cannot recover the switch without the configured credentials. • To enable bootloader protection, use the boot protect enable username username password password command.
