Troubleshooting the JRR200
Troubleshooting Resources for JRR200 Route Reflector
To troubleshoot JRR200 route reflector, use the command-line interface (CLI) and LEDs on the chassis:
LEDs—When the JRR200 route reflector detects an alarm condition, the status LED on the front panel glows red.
CLI—The CLI is the primary tool for controlling and troubleshooting hardware and network connectivity. Use the CLI to display more information about alarms. CLI commands display information about network connectivity derived from the ping and traceroute utilities.
JTAC—If you need assistance during troubleshooting, you can contact the Juniper Networks Technical Assistance Center (JTAC) by using the Web or by telephone. If you encounter software problems, or problems with hardware components not discussed here, contact JTAC.
