for each command are listed in Table 4.4 on page 36. Table 3.3 describes the access rights a user
may be given.
Access levels
When you specify a user’s permissions, you may either indicate the individual rights as listed in
Table 3.3 or you may indicate a predefined access level. The APPLIANCEADMIN and ADMIN
levels are equivalent to the following individual specifications:
The APPLIANCEADMIN level is equivalent to PALL, USER, SCON, SMON, PCON
and BREAK
The ADMIN level is equivalent to PALL, USER, SMON, PCON and BREAK
The third level (not APPLIANCEADMIN or ADMIN) is user. For preemption purposes, the
following hierarchy is used: APPLIANCEADMIN > ADMIN > user.
A user’s access level may be used for preemption. For example, assume User A is connected to a
port. User B tries to connect to the same port. If User B has an access level equal to or greater than
User A’s access level, then User B will be given the option of preempting User A. For more
information, see Preemption on page 20.
To manage a user’s access rights/levels:
1. To configure a user’s access rights/level, issue a User Add command, using the Access param-
eter to specify the rights or a level.
