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 EX Series switches.
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 EX Series switches, the traffic statistics fields
in show interfaces commands show only control traffic; the traffic statistics
do not include data traffic.
NOTE: EX Series switches do not support the collection and reporting of IPv6
transit statistics. Therefore, the IPv6 transit statistics field in the show
interfaces commands displays all values as 0.
Action 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.
