Using the Simple Network Management Protocol
ExtremeWare XOS 11.0 Concepts Guide 55
• System name—The system name enables you to enter a name that you have assigned to this switch.
The default name is the model name of the switch (for example, BD-1.2).
• System location (optional)—Using the system location field, you can enter the location of the switch.
Displaying SNMP Settings
To display the SNMP settings configured on the switch, use the following command:
show management
This command displays the following information:
• Enable/disable state for Telnet and SNMP access
• Login statistics
— Enable/disable state for idle timeouts
— Maximum number of CLI sessions
• SNMP community strings
• SNMP trap receiver list
• SNMP trap receiver source IP address
• SNMP statistics counter
SNMPv3
SNMPv3 is an enhanced standard for SNMP that improves the security and privacy of SNMP access to
managed devices and provides sophisticated control of access to the device MIB. The prior standard
versions of SNMP, SNMPv1 and SNMPv2c, provided no privacy and little security.
The following six RFCs provide the foundation for the Extreme Networks implementation of SNMPv3:
• RFC 2570, Introduction to version 3 of the Internet-standard Network Management Framework, provides an
overview of SNMPv3.
• RFC 2571, An Architecture for Describing SNMP Management Frameworks, talks about SNMP
architecture, especially the architecture for security and administration.
• RFC 2572, Message Processing and Dispatching for the Simple Network Management Protocol (SNMP),
talks about the message processing models and dispatching that can be a part of an SNMP engine.
• RFC 2573, SNMPv3 Applications, talks about the different types of applications that can be associated
with an SNMPv3 engine.
• RFC 2574, The User-Based Security Model for Version 3 of the Simple Network Management Protocol
(SNMPv3), describes the User-Based Security Model (USM).
• RFC 2575, View-based Access Control Model (VACM) for the Simple Network Management Protocol
(SNMP), talks about VACM as a way to access the MIB.
The SNMPv3 standards for network management were primarily driven by the need for greater security
and access control. The new standards use a modular design and model management information by
cleanly defining a message processing (MP) subsystem, a security subsystem, and an access control
subsystem.
The MP subsystem helps identify the MP model to be used when processing a received Protocol Data
Unit (PDU), which are the packets used by SNMP for communication. The MP layer helps in
