Note This tool can be effective to find out the number of LUNs exported by a storage subsystem, but it may
be ineffective when LUN Zoning/LUN Security tools are used.
SNMP and RMON Support
The Cisco MDS 9000 Family of switches provides extensive SNMPv1, v2, and v3support, including
Management Information Bases (MIBs) and notifications (traps and informs).
The applications provided by Cisco that use SNMP include Fabric Manager and CiscoWorks RME. Also,
the SNMP standard allows any third-party applications that support the different MIBs to manage and
monitor Cisco MDS 9000 Family switches.
SNMP v3 provides extended security. Each switch can be selectively enabled or disabled for SNMP
service. In addition, each switch can be configured with a method of handling SNMPv1 and v2 requests.
Note During initial configuration of your switch, the system prompts you to define SNMP v1 or V2
community strings and to create a SNMP v3 username and password.
Cisco MDS 9000 Family switches support over 50 different MIBs, which can be divided into the
following six categories:
• IETF Standards-based Entity MIBs (for example, RFC273 ENTITY-MIB) These MIBs are used to
report information on the physical devices themselves in terms of physical attributes etc.
• Cisco-Proprietary Entity MIBs (for example, CISCO-ENTITY-FRU-CONTROL-MIB) These
MIBs are used to report additional physical device information about Cisco-only devices such as
their configuration.
