QFX5220 Troubleshooting Resources Overview
To troubleshoot a QFX5220 problem, you can use:
•
Junos OS CLI
The CLI is the primary tool for controlling and troubleshooting hardware, Junos OS, routing protocols,
and network connectivity. CLI commands display information from routing tables, information specific
to routing protocols, and information about network connectivity derived from the ping and traceroute
utilities. For information about using the CLI to troubleshoot Junos OS, see the appropriate Junos OS
configuration guide.
•
Alarms and LEDs on the network ports, management panel, and components
When the Routing Engine detects an alarm condition, it lights the red or yellow alarm LED on the
management panel as appropriate. In addition, you can also use component LEDs and network port LEDs
to troubleshoot the QFX5220. For more information, see
“QFX5220 Management Panel” on page 45
