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.
Switch Management: Provides for out-of-band management of the switch
with SANsurfer Switch Manager, the SANsurfer Switch Manager Application
Application Programming Interface, SNMP, and CIM. 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 SANsurfer Switch Manager, SNMP, management
server, or the application programming interface. If you disable inband
management, you can no longer communicate with that switch by means
other than a direct Ethernet or serial connection.The default is enabled.
Secure Socket Layer (SSL): Provides for secure SSL connections for
SANsurfer Switch Manager, the SANsurfer Switch Manager web applet,
SANsurfer Switch Manager Application Programming Interface, and CIM.
This service must be enabled to authenticate users through a RADIUS
server when using SANsurfer Switch Manager. To enable secure SSL
connections, you must first synchronize the date and time on the switch and
workstation. Enabling SSL automatically creates a security certificate on the
switch. The default is enabled.
SANsurfer Switch Manager web applet: Provides for access to the
SANsurfer Switch Manager web applet. The web applet enables you to
point at a switch with an internet browser and run SANsurfer Switch
Manager 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 default is
enabled.
