User Capabilities and Security Levels
The functions of TermDSM commands are restricted by three different
security levels. Each security level is associated with the capabilities
necessary to use commands of that level. The security levels correspond
to the Online Diagnostic Subsystem.
Table 3-1 lists the security levels and the corresponding capabilities.
When a user issues a command, TermDSM checks the user's capability list
to verify that the user is authorized to use commands of that security
level. If the capabilities of the user are insufficient, the command is
not executed and an error message is displayed on the terminal.

A Word of Caution
Some TermDSM commands abort sessions and can cause a loss of data. If
used incorrectly, the commands can unnecessarily disrupt or abort user
sessions.
If more than one user is running TermDSM, it is not advisable for one
user of TermDSM to reset another user of TermDSM. (The user's port, ldev,
SIC, or DTC should not be reset.)
