Network Management Overview

Once you have installed the router into your network, you need to manage the router within your network. Router management can be divided into five tasks:

• Fault management—Monitor the router; detect and fix faults.
• Configuration management—Configure router attributes.
• Accounting management—Collect statistics for accounting purposes.
• Performance management—Monitor and adjust router performance.
• Security management—Control router access and authenticate users.

The JUNOS software network management features work in conjunction with an operations support system (OSS) to manage the router within the network. The JUNOS software can assist you in performing these management tasks, as described in Table 2.

Table 2: JUNOS Router Management Features

Task	JUNOS Software Feature
Fault management	Monitor and see faults using: Operational mode commands—For more information on operational mode commands, see the JUNOS Internet Software Network and Services Interfaces Command Reference and JUNOS Internet Software Protocols, Class of Service, Chassis, and Management Command Reference. SNMP MIBs—For more information about SNMP MIBs, see Juniper Networks Enterprise-Specific MIBs. Standard SNMP traps—For more information about standard SNMP traps, see Standard SNMP Traps. Enterprise-specific SNMP traps—For more information about enterprise-specific traps, see Juniper Networks Enterprise-Specific SNMP Traps. System log messages—For more information about how to configure system log messages, see the JUNOS Internet Software System Basics Configuration Guide. For more information about how to view system log messages, see the JUNOS Internet Software System Log Messages Reference.
Configuration management	Configure router attributes using the command-line interface (CLI) and the JUNOScript API. For more information on configuring the router using the CLI, see the JUNOS Internet Software System Basics Configuration Guide. For more information on configuring the router using the JUNOScript API, see the JUNOScript API Reference and the JUNOScript API Guide. Configuration Management MIB—For more information about the Configuration Management MIB, see Juniper Networks Enterprise-Specific MIBs.
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 on collecting statistics, see Configure Accounting Options. 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. 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 on classes, see Juniper Networks Enterprise-Specific MIBs,Configure Class Usage Profiles, the JUNOS Internet Software Network Interfaces and Class of Service Configuration Guide, and the JUNOS Internet Software Policy Framework Configuration Guide. Count packets as part of a firewall filter. For more information on firewall filter policies, see Juniper Networks Enterprise-Specific MIBs, and the JUNOS Internet Software Policy Framework Configuration Guide. Sample traffic, collect the samples, and send the collection to a host running the CAIDA cflowd utility. For more information on CAIDA and cflowd, see the JUNOS Internet Software Policy Framework Configuration Guide.
Performance management	Monitor performance in the following ways: Use operational mode commands. For more information on monitoring performance using operational mode commands, see the JUNOS Internet Software Protocols, Class of Service, Chassis, and Management Command Reference. As part of a firewall filter. For more information on performance monitoring using firewall filters, see the JUNOS Internet Software Configuration Policy Framework Guide. Sample traffic, collect the samples, and send the samples to a host running the CAIDA cflowd utility. For more information on CAIDA and cflowd, see the JUNOS Internet Software Policy Framework Configuration Guide. Use the enterprise-specific class-of-service MIB. For more information on this MIB, see Juniper Networks Enterprise-Specific MIBs.
Security management	Assure security in your network in the following ways: Control access to the router and authenticate users. For more information on access control and user authentication, see the JUNOS Internet Software System Basics Configuration Guide. Control access to the router using SNMPv3 and SNMP over IPv6. For more information, see Configure the Local Engine ID and Trace SNMP Activity.
