Fabric Services
Fabric services security includes SNMP and In-band management. Simple
Network Management Protocol (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 basically 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 using the
SNMP Properties dialog. If SNMP is enabled (default) and the read and write
community strings have not been changed from their defaults, you risk unwanted
access to the switch. Refer to “Enabling SNMP Configuration” on page 3-2 for
more information. SNMP is enabled by default.
In-band management is the ability to manage switches across inter-switch links
using SANsurfer Switch Manager, SNMP, management server, or the application
programming interface. The switch comes from the factory with in-band
management enabled. If you disable in-band management on a particular switch,
you can no longer communicate with that switch by means other than a direct
Ethernet or serial connection. Refer to “Enabling In-band Management” on
page 3-2 for more information.
