Understanding Device Management Functions in JUNOS Software

Fault management

Monitor and see faults using:

• Operational mode commands—For more information about operational mode commands, see the Junos System Basics and Services Command Reference, Junos Interfaces Command Reference, and Junos Routing Protocols and Policies Command Reference.
• SNMP MIBs—For more information about SNMP MIBs supported by JUNOS Software, see “Standard SNMP MIBs Supported by JUNOS Software” and “Juniper Networks Enterprise-Specific MIBs” in the JUNOS Software SNMP MIBs and Traps Reference.
• Standard SNMP traps—For more information about standard SNMP traps, see the “Standard SNMP Traps Supported on Devices Running JUNOS Software” in the JUNOS Software SNMP MIBs and Traps Reference.
• Enterprise-specific SNMP traps—For more information about enterprise-specific traps, see “Juniper Networks Enterprise-Specific SNMP Traps” in the JUNOS Software SNMP MIBs and Traps Reference.
• System log messages—For more information about how to configure system log messages, see the Junos System Basics Configuration Guide. For more information about how to view system log messages, see the Junos System Log Messages Reference.

Configuration management

• Configure router attributes using the command-line interface (CLI), the JUNOScript API, and the NETCONF API. For more information about configuring the router using the CLI, see the Junos System Basics Configuration Guide. For more information about configuring the router using the APIs, see the JUNOScript API Guide and NETCONF API Guide.
• Configuration Management MIB—For more information about the Configuration Management MIB, see the “Configuration Management MIB” in the JUNOS Software SNMP MIBs and Traps Reference.

Accounting management

Perform the following accounting-related tasks:

• Collect statistics for interfaces, firewall filters, destination classes, source classes, and the Routing Engine. For more information about collecting statistics, see Accounting Options Configuration.
• Use interface-specific traffic statistics and other counters, available in the Standard Interfaces MIB, Juniper Networks enterprise-specific extensions to the Interfaces MIB, and media-specific MIBs, such as the enterprise-specific ATM MIB.
• Use per-ATM virtual circuit (VC) counters, available in the enterprise-specific ATM MIB. For more information about the ATM MIB, see the JUNOS Software SNMP MIBs and Traps Reference.
• Group source and destination prefixes into source classes and destination classes and count packets for those classes. Collect destination class and source class usage statistics. For more information about classes, see “Destination Class Usage MIB” and “Source Class Usage MIB” in the JUNOS Software SNMP MIBs and Traps Reference, Configuring Class Usage Profiles, the Junos Network Interfaces Configuration Guide, and the Junos Policy Framework Configuration Guide.
• Count packets as part of a firewall filter. For more information about firewall filter policies, see “Juniper Networks Enterprise-Specific MIBs” in the JUNOS Software SNMP MIBs and Traps Reference and the Junos Policy Framework Configuration Guide.
• Sample traffic, collect the samples, and send the collection to a host running the CAIDA cflowd utility. For more information about CAIDA and cflowd, see the Junos Policy Framework Configuration Guide.

Performance management

Monitor performance in the following ways:

• Use operational mode commands. For more information about monitoring performance using operational mode commands, see the Junos System Basics and Services Command Reference.
• Use firewall filter. For more information about performance monitoring using firewall filters, see the Junos Policy Framework Configuration Guide.
• Sample traffic, collect the samples, and send the samples to a host running the CAIDA cflowd utility. For more information about CAIDA and cflowd, see the Junos Policy Framework Configuration Guide.
• Use the enterprise-specific Class-of-Service MIB. For more information about this MIB, see the “Class-of-Service MIB” in the JUNOS Software SNMP MIBs and Traps Reference.

Security management

Assure security in your network in the following ways:

• Control access to the router and authenticate users. For more information about access control and user authentication, see the Junos System Basics Configuration Guide.
• Control access to the router using SNMPv3 and SNMP over IPv6. For more information, see Configuring the Local Engine ID and Tracing SNMP Activity on a Device Running JUNOS Software.
