Description
This article describes how to check interface information (for example, link status) via CLI.
There are times when it is required to check the interface link status via the command line interface (CLI) only.
Scope
FortiGate interface management.
Solution
Use the command indicated in the related document to list the FortiGate's physical network interface's information, such as IP address, physical link status, speed, and duplex mode:
system interface physical
The original command, get system interface shows more details on the interface's information. Furthermore, the output shows all logical interfaces such as SSL VPN, VPN, VLAN, and software switch interfaces.
FGT #get system interface
Example output:
== [ wan1 ]
name: wan1 mode: dhcp ip: 192.168.1.3 255.255.255.0 status: up netbios-forward: disable type: physical netflow-sampler: disable sflow-sampler: disable src-check: enable explicit-web-proxy: disable explicit-ftp-proxy: disable proxy-captive-portal: disable mtu-override: disable wccp: disable drop-overlapped-fragment: disable drop-fragment: disable
== [ wan2 ]

== [ modem ]

== [ lan ]

== [ p1-VPN ]
name: p1-VPN ip: 0.0.0.0 0.0.0.0 status: up netbios-forward: disable type: tunnel netflow-sampler: disable sflow-sampler: disable src-check: enable explicit-web-proxy: disable explicit-ftp-proxy: disable proxy-captive-portal: disable wccp: disable
== [ VLAN]
name: VLAN mode: static ip: 0.0.0.0 0.0.0.0 status: up netbios-forward: disable type: vlan netflow-sampler: disable sflow-sampler: disable src-check: enable explicit-web-proxy: disable explicit-ftp-proxy: disable proxy-captive-portal: disable switch-controller-feature: none mtu-override: disable wccp: disable drop-overlapped-fragment: disable drop-fragment: disable
The command below provides the physical interface link state information:
FGT # diagnose hardware device nic <interface name>
Example output:
diagnose hard deviceinfo nic wan1
========== Link Status ==========
Admin :up
netdev status :up
autonego_setting:1
link_setting :1
speed_setting :10
duplex_setting :0
Speed :1000
Duplex :Full
link_status :Up
