Accessing the Switch

To enable better switch management and user accountability, three levels or classes of user

access have been implemented on the

G8000. Levels of access to CLI, Web management func-

tions, and screens increase as needed to perform various switch management tasks. Conceptu-

ally, access classes are defined as follows:

 User interaction with the switch is completely passive—nothing can be changed on the

G8000. Users may display information that has no security or privacy implications, such as

switch statistics and current operational state information.

 Operators can make temporary changes on the

G8000. These changes are 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 configu-

ration—changes that are persistent across a reboot/reset of the switch. Administrators can

access switch functions to configure and troubleshoot problems on the

G8000. 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

“Setting Passwords” on page 20.
