Monitoring Interface Status and Traffic


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.


To view general interface information in the J-Web interface such as available interfaces, select Monitor > Interfaces. Click any interface to view details about its status.

To set up interface monitoring for the QFX Series, select a member from the Port for FPC list. Details such as the admin status and link status are displayed in the table.

Note: By default, the details of the first member in the Port for FPC drop-down list are displayed.

You have the following options:
