Monitoring Interface Status and Traffic
Purpose
This topic applies only to the J-Web Application package.
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.
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.
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.
To set up interface monitoring for Virtual Chassis and EX8200 switches, select a member from the Port for Member list. Details such as the admin status and link status are displayed in the table. For an EX8200 Virtual Chassis setup, select the member, FPC, and the required interface.
By default, the details of the first member in the FPC list is displayed. In an EX8200 Virtual Chassis setup, details of the first member and the first FPC is displayed.
You have the following options:
Start/Stop—Starts or stops monitoring the selected interface.
Show Graph—Displays input and output packet counters and error counters in the form of charts. Click the pop-up icon to view the graph in a separate window.
Details—Displays interface information such as general details, traffic statistics, I/O errors, CoS counters, and Ethernet statistics.
Refresh Interval (sec)—Displays the time interval you have set for page refresh.
Clear Statistics—Clears the statistics for the interface selected from the table.
Using the CLI:
To view interface status for all the interfaces, enter show interfaces xe.
To view status and statistics for a specific interface, enter show interfaces xe-interface-name.
To view status and traffic statistics for all interfaces, enter either show interfaces xe detail or show interfaces xe extensive.
Meaning
In the J-Web interface the charts displayed are:
Bar charts—Display the input and output error counters.
Pie charts—Display the number of broadcast, unicast, and multicast packet counters.
For details about output from the CLI commands, see show interfaces ge- (Gigabit Ethernet) or show interfaces xe- (10-Gigabit Ethernet).
