3.6.2

Fabric Services

Fabric services include security-related functions such as inband management

and SNMP. Inband management is the ability to manage switches across

inter-switch links using SANbox Manager, SNMP, management server, or the

application programming interface. The switch comes from the factory with inband

management enabled. If you disable inband management on a particular switch,

you can no longer communicate with that switch by means other than a direct

Ethernet or serial connection.

You can also enable or disable the Simple Network Management Protocol

(SNMP). SNMP is the protocol governing network management and monitoring of

network devices. SNMP security consists of a read community string and a write

community string, that are the passwords that control read and write access to the

switch. The read community string ("public") and write community string ("private")

are set at the factory to these well-known defaults and should be changed if

SNMP is enabled. If SNMP is enabled (default) and the the read and write

community strings have not been changed from their defaults, you risk unwanted

access to the switch. SNMP is enabled by default. Consider how you want to

manage the fabric and what switches you do not want managed or monitored

through other switches.

Fabric Management

The SANbox Manager application and CLI execute on a management workstation

that provides for the configuration, control, and maintenance of the fabric.

Supported platforms include Windows, Solaris, and Linux. The SANbox Manager

application can manage multiple fabrics. Consider how many fabrics will be

managed, how many management workstations are needed, and whether the

fabrics will be managed with the CLI or SANbox Manager.

A switch supports a combined maximum of 19 logins reserved as follows:

 4 logins or sessions for internal applications such as management server

and SNMP

 9 high priority Telnet sessions

 6 logins or sessions for SANbox Manager inband and out-of-band logins,

Application Programming Interface (API) inband and out-of-band logins, and

Telnet logins. Additional logins will be refused.
