NE2552E Application Guide for ENOS 8.4
Switch Login Levels
To enable better switch management and user accountability, three levels or classes
of user access have been implemented on the NE2552E. 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 NE2552E. 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 NE2552E. 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 NE2552E. 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 user names and
passwords. Once you are connected to the switch via console, 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 88 .
