Clicking on the Users tab of the IPMI View management session in the Viewing Window (as shown in

Figure 8-1 and 8-2) gives you detailed information on the Users management, and the paging severity

thresholds for IPMI 1.5.

We strongly suggest you change passwords immediately to prevent malicious users getting control

before you.

• USERS

There are several buttons that allow you to add/delete a user, set user privileges, change passwords and

enable/disable paging.

There are six privilege level groups, Callback, User, Operator, Administrator, OEM, and No Access.

Only the first four privilege levels are implemented. Privilege Levels determine which IPMI commands

a given user can execute over a given channel. Privilege Limits set the maximum privilege level that a

user can operate at. A user is configured with a given maximum privilege limit for each channel. Thus, a

user can operate at a privilege level that is no higher than his group privilege limit.

Group Privilege Levels

Callback This may be considered the lowest privilege level. Only commands necessary to

support initiating a Callback are allowed. (Only available for IPMI 1.5.)

User Only ‘benign’ commands are allowed. These are primarily commands that read data

structures and retrieve status. Commands that can be used to alter BMC configuration,

write data to the BMC or other management controllers or perform system actions

such as resets, power on/off, and watchdog activation are not allowed.

Operator All BMC commands are allowed, except for configuration commands that can change

the behavior of the out-of-band interfaces. For example, Operator privilege does not

allow the capability to disable individual channels or change user access privileges.

Administrator All BMC commands are allowed, including configuration commands. An

Administrator can even execute configuration commands that would disable the

channel that the Administrator is communicating over.

Clicking on Paging Setting allows you to set the parameters for an individual user (Figure 8-3). There

are two types of paging services: Numeric paging and alphanumeric paging. To use a paging service, a

modem must be connected to the RS232 connector on the BMC (Figure 7-2).
