Interfaces

 

Monitoring Interfaces

Purpose

View general information about all physical and logical interfaces for a device.

Action

Enter the following show commands in the CLI to view interface status and traffic statistics.

  • show interfaces terse

    Note

    On SRX Series devices, when configuring identical IPs on a single interface, you will not see a warning message; instead, you will see a syslog message.

  • show interfaces extensive

  • show interfacesinterface-name

Note

If you are using the J-Web user interfaces, select Monitor>Interfaces in the J-Web user interface. The J-Web Interfaces page displays the following details about each device interface:

  • Port—Indicates the interface name.

  • 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).

  • Address—Indicates the IP address of the interface.

  • Zone—Indicates whether the zone is an untrust zone or a trust zone.

  • Services—Indicates services that are enabled on the device, such as HTTP and SSH.

  • Protocols—Indicates protocols that are enabled on the device, such as BGP and IGMP.

  • 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.
