Monitoring Interfaces
To view general information about all device physical and logical interfaces, select Monitor > Interfaces in the J-Web user interface.
 | After you make changes to the configuration in this window, you must commit the changes immediately for them to take effect. To commit all changes to the active configuration, select Commit Options > Commit. See Using the Commit Options to Commit Configuration Changes (J-Web Procedure) for details about all commit options. |
Alternatively, you can enter the following show commands in the CLI editor to view interface status and traffic statistics:
- show interfaces terse
- show interfaces detail
- show interfaces extensive
- show interfaces interface-name
The J-Web Monitor Interfaces page displays the following details about each device interface:
- Port—Indicates the interface name. (For information about interface naming conventions, see the Junos Software Interfaces and Routing Configuration Guide.)
- Admin Status—Indicates whether the interface is enabled (Up) or disabled (Down).
- Link Status—Indicates whether the interface is linked (Up) or not linked (Down).
- Input Rate graph—Displays interface bandwidth utilization. Input rates are shown in bytes per second.
- Output Rate graph—Displays interface bandwidth utilization. Output rates are shown in bytes per second.
- Error Counters chart—Displays input and output error counters in the form of a bar chart.
- Packet Counters chart—Displays the number of broadcast, unicast, and multicast packet counters in the form of a pie chart. (Packet counter charts are supported only for interfaces that support MAC statistics.)
To change the interface display, use the following options:
- Port for FPC—Controls the member for which information is displayed.
- Start/Stop button—Starts or stops monitoring the selected interfaces.
- Show Graph—Displays input and output packet counters and error counters in the form of charts.
- Pop-up button—Displays the interface graphs in a separate pop-up window.
- Details—Displays extensive statistics about the selected interface, including its general status, traffic information, IP address, I/O errors, class-of-service data, and statistics.
- Refresh Interval—Indicates the duration of time after which you want the data on the page to be refreshed.
- Clear Statistics—Clears the statistics for the selected interface.
