Device and Network Management Features

Alarms and LEDs on the switch—Display status of hardware components and indicate warning or error conditions.

Fault management

Firewall filters—Control the packets that are sent to and from the network, balance network traffic, and optimize performance.

Performance management

In-band management—Enables connection to the switch using the same interfaces through which customer traffic flows. Communication between the switch and a remote console is enabled using SSH and Telnet services. SSH provides secure encrypted communications, whereas Telnet provides unencrypted, and therefore less secure, access to the switch.

Remote access management

Juniper Networks Junos OS automation scripts—Configuration and operation automation tools provided by Junos OS include commit scripts, operation scripts, event scripts, and event policies. Commit scripts enforce custom configuration rules, whereas operation scripts, event policies, and event scripts automate network troubleshooting and management.

Junos OS command-line interface (CLI)— CLI configuration statements enable you to configure the switch based on your networking requirements, such as security, service, and performance.

Junos Space software—Multipurpose GUI-based network management system includes a base platform, the Network Application Platform, and other optional applications such as Ethernet Design, Service Now, Service Insight, and Virtual Control.

Junos XML API—XML representation of Junos OS configuration statements and operational mode commands. The Junos XML API also includes tag elements that are the counterpart to Junos CLI configuration statements.

NETCONF XML management protocol—XML-based management protocol that client applications use to request and change configuration information on routing, switching, and security platforms running Junos OS. The NETCONF XML management protocol defines basic operations that are equivalent to Junos OS CLI configuration mode commands. Client applications use the protocol operations to display, edit, and commit configuration statements (among other operations), as administrators use CLI configuration mode commands such as show, set, and commit to perform those operations.

Operational mode commands:

• Monitor switch performance. For example, the show chassis routing-engine command shows the CPU utilization of the Routing Engine. High CPU utilization of the Routing Engine can affect performance of the switch.

• View current activity and status of the device or network. For example, you can use the ping command to monitor and diagnose connectivity problems, and the traceroute command to locate points of failure on the network.

Out-of-band management—Enables connection to the switch through a management interface. Out-of-band management is supported on two dedicated management Ethernet interfaces as well as on the console and auxiliary ports. The management Ethernet interfaces connect directly to the Routing Engine. Transit traffic is not allowed through the interfaces, which ensures the congestion or failures in the transit network do not affect the management of the switch.

Remote access management

SNMP Configuration Management MIB—Provides notification for configuration changes in the form of SNMP traps. Each trap contains the time at which the configuration change was committed, the name of the user who made the change, and the method by which the change was made. History of the last 32 configuration changes is placed in jnxCmChgEventTable.

Configuration management

SNMP MIBs and traps—Enable the monitoring of network devices from a central location. Use SNMP requests such as get and walk to monitor and view system activity.

The QFX3500 switch supports SNMP Version 1 (v1), v2, and v3, and both standard and Juniper Networks enterprise-specific MIBs and traps.

Fault management

System log messages—Log details of system and user events, including errors. You can specify the severity and type of system log messages you wish to view or save, and configure the output to be sent to local or remote hosts.
