Monitoring Interfaces
Purpose
View general information about all physical and logical interfaces for a device.
Action
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.
Alternatively, you can enter the following show commands in the CLI to view interface status and traffic statistics:
- show interfaces terse
On SRX Series devices, on configuring identical IPs on a single interface, you will not see a warning message; instead, you will see a syslog message.
- show interfaces detail
- show interfaces extensive
- show interfaces interface-name
