Exploring Network Status

Exploring Network Status
This section shows how to use the nmcli command-line tool to examine the status of NetworkManager’s connections and devices.

Show the status of devices known to NetworkManager:

$ nmcli d

Show more information for this option:

$ nmcli d --help

Show the current status of each of NetworkManager’s connections:

$ nmcli c

Command “c” is for connections but is a abbreviated form of the real command “connections”. As for the devices command, “–help” shows more information for this option. Finally, we can see the state of radio interfaces, including WiFi and WWAN (cellular) with:

$ nmcli r

enabled enabled enabled enabled
It is important to make sure that WiFi/WWAN radios are enabled so the respective connection types can establish a connection (we will specify how to this in following sections). As with the other commands, “–help” shows usage information.

Observe NetworkManage activity (changes in connectivity state, devices or connection properties):

$ nmcli monitor

See nmcli connection monitor and nmcli device monitor to watch for changes in certain connections or devices.
