Accessing The Switch - HP 445860-B21 - 10Gb Ethernet BL-c Switch Command Reference Manual

Accessing the switch

To enable better switch management and user accountability, the switch provides different levels or
classes of user access. Levels of access to the CLI and Web management functions and screens increase
as needed to perform various switch management tasks. The three levels of access are:
User—User interaction with the switch is completely passive; nothing can be changed on the switch.
Users may display information that has no security or privacy implications, such as switch statistics
and current operational state information.
Operator—Operators can only effect temporary changes on the switch. These changes will be lost
when the switch is rebooted/reset. Operators have access to the switch management features used
for daily switch operations. Because any changes an operator makes are undone by a reset of the
switch, operators cannot severely impact switch operation, but do have access to the Maintenance
menu.
Administrator—Only administrators can make permanent changes to the switch configuration,
changes that are persistent across a reboot/reset of the switch. Administrators can access switch
functions to configure and troubleshoot problems on the switch. Because administrators can also
make temporary (operator-level) changes as well, they must be aware of the interactions between
temporary and permanent changes.
Access to switch functions is controlled through the use of unique usernames and passwords. Once you
are connected to the switch via the local console, Telnet, or SSH, you are prompted to enter a password.
The password entered determines the access level. The default user names/password for each access
level is listed in the following table.
NOTE:
It is recommended that you change default switch passwords after initial configuration and
as regularly as required under your network security policies. For more information, see the "Setting
passwords" section in the "First-time configuration" chapter.

NOTE: With the exception of the admin user, setting the password to an empty value can disable
access to each user level.
Once you enter the administrator password and it is verified, you are given complete access to the switch.
The user has no direct responsibility for switch management. He or she can view all switch status
information and statistics, but cannot make any configuration changes to the switch. The user
account is enabled by default, and the default password is user.
The operator manages all functions of the switch. The operator can reset ports or the entire
switch. By default, the operator account is disabled and has no password.
The super user administrator has complete access to all menus, information, and configuration
commands on the switch, including the ability to change both the user and administrator
passwords. The admin account is enabled by default, and the default password is admin.
