Caution – Use caution when disabling the Embedded GUI, GUI Mgmt, and Telnet,
as it is possible to disable all access to the switch except through a serial connection.
■ Embedded GUI (Graphical User Interface) — allows users to point a browser at
the switch and use the QuickTools web applet.
■ GUI Mgmt — allows out-of-band management of the switch from the switch
management application (GUI). If disabled, the switch can not be specified as the
entry switch for a fabric in the GUI, but can still be managed through an in-band
connection.
■ Telnet (Command line interface) — allows users to manage the switch through a
Telnet command line interface session. Disabling Telnet access to the switch is not
recommended.
■ SNMP (Simple Network Management Protocol) — allows management of the
switch through third-party applications that use SNMP.
■ NTP (Network Time Protocol) — allows the switch to obtain its time and date
settings from an NTP server. Configuring all of your switches and your
workstations to utilize NTP will keep their date/time settings in sync and will
prevent difficulties with SSL certificates and event logs.
