Managing system services
The System Services dialog box (
) provides a central location for you to enable or disable any of
the external user services such as Simple Network Management Protocol (SNMP), embedded web applet,
command line interface, Network Time Protocol (NTP), Common Information Model (CIM), and Call
Home. To display the System Services dialog box, select Switch > Services.

IMPORTANT:
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.
The following system services are available:
•
Embedded GUI (Graphical User Interface)—Enables users to point a browser at the switch and use the
Enterprise Fabric Management Suite application.
•
GUI Mgmt—Enables out-of-band management of the switch from the switch management application
(GUI). If this service is disabled, the switch cannot be specified as the entry switch for a fabric in the
GUI, but can still be managed through an in-band connection.
•
SSL (Secure Sockets Layer)—Enables secure encrypted communications between the switch
management application (GUI) and the switch. SSL must be enabled to configure device security and
RADIUS servers. SSL certificates are generated on the switch with the switch date/time and validated
with the workstation’s date/time. If the switch and workstation date/time are not synchronized, invalid
certificates are generated and prevent an SSL connection from being established between the switch
and switch management application (GUI). After enabling the SSL service, you must then log off the
fabric and log on again to establish a secure connection. To disable SSL when using a user
authentication RADIUS server, the RADIUS authentication order must first be set to Local.
•
Telnet (Command line interface)—Enables users to manage the switch through a Telnet command line
interface session. Disabling Telnet access to the switch is not recommended.
•
SSH (Secure SHell)—Enables secure encrypted Telnet command line interface sessions with the switch.
To manage a switch over a secure Telnet connection, the SSH service must be enabled, and an SSH
client must be running on your workstation.
•
SNMP (Simple Network Management Protocol)—Enables management of the switch through
third-party applications that use SNMP.
