38 Chapter 1: Switch Administration BMD00220, October 2010
Switch Login Levels
To enable better switch management and user accountability, three levels or classes of user access
have been implemented on the G8124. Levels of access to CLI, Web management functions, and
screens increase as needed to perform various switch management tasks. Conceptually, access
classes are defined as follows:
User interaction with the switch is completely passive—nothing can be changed on the G8124.
Users may display information that has no security or privacy implications, such as switch
statistics and current operational state information.
Operators can only effect temporary changes on the G8124. 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.
Administrators are the only ones that may 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 G8124. 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 surnames and passwords. Once
you are connected to the switch via local Telnet, remote Telnet, or SSH, you are prompted to enter
a password. The default user names/password for each access level are 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 “Changing
the Switch Passwords” on page 61.
Note – With the exception of the “admin” user, access to each user level can be disabled by setting
the password to an empty value.
