监控接口和交换功能
本节介绍如何监控接口和交换功能。
显示实时接口信息
输入命令以 monitor interface 显示有关物理或逻辑接口的实时流量、错误、告警和过滤器统计信息：
user@host> monitor interface (interface-name | traffic)
替换为 interface-name 物理或逻辑接口的名称。如果指定该 traffic 选项，将显示所有活动接口的统计信息。
实时统计信息每秒更新一次。和Current deltaDelta列显示自monitor interface输入命令或清除增量计数器以来统计信息计数器发生更改的数量。 表 1 并使用表 2和traffic选项列出用于控制显示interface-name的键。（键不区分大小写。

Monitor 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 terseNote：On SRX Series Firewalls, when configuring identical IPs on a single interface, you will not see a warning message; instead, you will see a syslog message.
show interfaces extensiveshow interfacesinterface-name
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.
