Monitoring Interface Status and Traffic

Purpose

Use the monitoring functionality to view interface status or to monitor interface bandwidth utilization and traffic statistics on the QFX Series.

The J-Web interface monitors interface bandwidth utilization and plots real-time charts to display input and output rates in bytes per second. In addition, the Interface monitoring page displays input and output packet counters and error counters in the form of charts.

Alternatively, you can enter the show commands in the CLI to view interface status and traffic statistics.

Note: For logical interfaces on the QFX Series, the traffic statistics fields in show interfaces commands show only control traffic; the traffic statistics do not include data traffic.

Action
