3.1
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
System Services or SNMP Properties dialogs. 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 QuickTools, 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.
