Switch Services - HP StorageWorks SN6000 Installation And Reference Manual

Switch services

You can configure your switch to suit the demands of your environment by enabling or disabling a variety
of switch services. Familiarize yourself with the following switch services and determine which ones you
need.
• Telnet: Provides for the management of the switch over a Telnet connection. Disabling this service is not
recommended. The default is enabled.
• Secure Shell (SSH): Provides for secure remote connections to the switch using SSH. Your workstation
must also use an SSH client. The default is disabled.
• GUI Management: Provides for out-of-band management of the switch with Simple SAN Connection
Manager, QuickTools, Enterprise Fabric Management Suite, SNMP, and SMI-S. If this service is
disabled, the switch can only be managed inband or through the serial port. The default is enabled.
• Inband Management: Provides for the management of the switch over an inter-switch link using Simple
SAN Connection Manager, QuickTools, Enterprise Fabric Management Suite, SNMP, or management
server. If you disable inband management, you can no longer communicate with that switch by means
other than an Ethernet or serial connection. The default is enabled.
• Secure Socket Layer (SSL): Provides for secure SSL connections for the QuickTools web applet,
Enterprise Fabric Management Suite, and SMI-S. This service must be enabled to authenticate users
through a Remote Authentication Dial-in Service (RADIUS) server. To enable secure SSL connections,
you must first synchronize the date and time on the switch and the workstation. Enabling SSL
automatically creates a security certificate on the switch. The default is disabled.
• QuickTools web applet (Embedded GUI): Provides for access to the QuickTools web applet. QuickTools
enables you to point at a switch with an internet browser and manage the switch through the browser.
The default is enabled.
• Simple Network Management Protocol (SNMP): Provides for the management of the switch through
third-party applications that use the Simple Network Management Protocol (SNMP). Security consists
of a read community string and a write community string that serve as passwords that control read and
write access to the switch. These strings are set at the factory to these well-known defaults and should
be changed if SNMP is to be enabled. Otherwise, you risk unwanted access to the switch. The switch
supports SNMP versions 1, 2, and 3. The default configuration enables SNMP and disables SNMP
version 3 security.
• Common Information Model (CIM): Provides for the management of the switch through third-party
applications that use the Storage Management Initiative–Specification (SMI-S). The default is enabled.
• File Transfer Protocol (FTP): Provides for transferring files rapidly between the workstation and the switch
using FTP. The default is enabled.
• Management Server (MS): Enables or disables the management of the switch through third-party
applications that use FC-GS-3 Management Server. The default is disabled.
• Call Home: If enabled and configured, switches can send alerts regarding events and faults to Email
addresses. Users can configure the type of events and where the alerts are sent.
IMPORTANT:
service has no relationship with the HP Call Home feature, which notifies only HP services.
Provides for automated e-mail notification of switch status and operating conditions based on specified
event severity levels. The default is enabled. The Call Home service requires an Ethernet connection to
at least one Simple Mail Transfer Protocol (SMTP) server. You must configure the Call Home service to
do the following:
• Enable primary and secondary SMTP servers and specify their IP addresses
• Specify contact information
Configure one or more Call Home profiles to specify e-mail recipients, message format, and the event
severity level that will initiate a message. In addition, you can configure periodic event data collection
and processing through the Tech_Support_Center profile for automated status and trend analysis.
