I'm trying to create a static ip using nmcli in CentOS 6.9 but couldn't do so, as the man nmcli is not showing enough options like the online examples. To make you all to understand I'll paste the man page here; please tell me where I am going wrong or is it the distribution's fault, as I found many discrepancies after changing from Ubuntu.

NMCLI(1)                                                              NMCLI(1)



NAME

       nmcli - command-line tool for controlling NetworkManager



SYNOPSIS

       nmcli  [ OPTIONS ] OBJECT { COMMAND | help }



       OBJECT := { nm | con | dev }



       OPTIONS := {

       -t[erse]

       -p[retty]

       -m[mode] tabular | multiline

       -f[ields] <field1,field2,...> | all | common

       -e[scape] yes | no

       -v[ersion]

       -h[elp]

       }







DESCRIPTION

       nmcli is a command-line tool for controlling NetworkManager and getting its status.  It is not meant as a replacement of nm-applet or other similar clients.  Rather it’s a complementary utility to these pro-

       grams.  The main nmcli’s usage is on servers, headless machines or just for power users who prefer the command line.



       The use cases comprise:



       —   Initscripts: ifup/ifdown can utilize NetworkManager via nmcli instead of having to manage connections itself and possible interfere with NetworkManager.



       —   Servers, headless machines: No GUI is available; then nmcli is used to talk directly to NetworkManager and control only system-wide connections.



       —   User sessions: For this case, nmcli can talk to nm-applet to find user connections.  It can still talk directly to NetworkManager for manipulating these connections.  As nmcli doesn’t have direct access

           to user configuration data in GConf, nm-applet handles that itself.  That may, for example, cause the applet to pop up keyring dialogs when secrets are needed.



   OPTIONS

       -t, --terse

              Output is terse.  This mode is designed and suitable for computer (script) processing.



       -p, --pretty

              Output is pretty.  This causes nmcli to produce easy readable outputs for humans, i.e. values are aligned, headers are printed, etc.



       -m, --mode tabular | multiline

              Switch between tabular and multiline output.  If omitted, default is tabular for most commands.  For the commands producing more structured information, that cannot be displayed on a single line,

              default is multiline. Currenly, they are:

                ’nmcli con list id|uuid <name>’

                ’nmcli dev list’

              tabular   - Output is a table where each line describes a single entry.  Columns define particular properties of the entry.

              multiline - Each entry comprises more lines, each property on its own line.  The values are prefixed with the property name.



       -f, --fields <field1,field2,...> | all | common

              This option is used to specify what fields (column names) should be printed.  Valid field names differ for specific commands. List available fields by providing an invalid value to the --fields

              option.

              all is used to print all valid field values of the command.  common is used to print common field values of the command.  If omitted, default is common.  The option is mandatory when --terse is used.

              In this case, generic values all and common cannot be used.  (This is to maintain compatibility when new fields are added in the future).



       -e, --escape yes | no

              Whether to escape ’:’ and ’’ characters in terse tabular mode.  The escape character is ’’.  If omitted, default is yes.



       -v, --version

              Show nmcli version.



       -h, --help

              Print help information.





   OBJECT

       nm     NetworkManager

              Use this object to inquire and change state of NetworkManager.



          COMMAND := { status | sleep | wakeup | wifi | wwan }



              status

                     Show overall status of NetworkManager.  This is the default action, when no command is provided to nm object.

                     Reference to D-Bus:

                     No simple reference.



              sleep

                     Put NetworkManager to sleeping mode.  Thus all interfaces that NetworkManager manages are deactivated.

                     arguments: TRUE



              wakeup

                     Awake NetworkManager from sleep.  When NetworkManager is awaken, devices are available to be activated.

                     Reference to D-Bus:

                     interface: org.freedesktop.NetworkManager

                     arguments: FALSE



              wifi [on|off]

                     Inquire or set status of WiFi in NetworkManager.  Without any further argument, WiFi status is printed; on enables WiFi; off disables WiFi.

                     Reference to D-Bus:

                     No simple reference.



              wwan [on|off]

                     Inquire or set status of WWAN in NetworkManager.  Without any further argument, WWAN status is printed; on enables WWAN; off disables WWAN.

                     Reference to D-Bus:

                     No simple reference.



       con    Connections

              Get information about NetworkManager’s connections.



       con    Connections

              Get information about NetworkManager’s connections.



          COMMAND := { list | status | up | down }



              list [id <id> | uuid <id> | system | user]

                     List configured connections.  Without a parameter, configured connection from both system and user settings services are listed.  system argument filters only system-wide connections, user

                     prints user connections only.  In order to get connection details, id with connection’s name or uuid with connection’s UUID shall be specified.  When no command is given to con object, the

                     default action is ’nmcli con list’.

                     Reference to D-Bus:

                     No simple reference.



              status

                     Print status of active connections.

                     Reference to D-Bus:

                     No simple reference.



              up id <id> | uuid <id> [iface <iface>] [ap <hwaddr>] [--nowait] [--timeout <timeout>]

                     Activate a connection.  The connection is identified by its name using id or UUID using uuid.  For requiring particular device to activate the connection on, iface option with interface name

                     should be given.  ap option can further concretize what AP should be used in case of WiFi connection.  --nowait option causes nmcli to exit immediately and not to wait for command completion.

                     --timeout option provides a means to specify how long to wait for operation completion.

                     Reference to D-Bus:

                     interface: org.freedesktop.NetworkManager

                     method:    ActivateConnection

                     arguments: according to arguments



              down id <id> | uuid <id>

                     Deactivate a connection.  The connection is identified by its name using id or UUID using uuid.

                     Reference to D-Bus:

                     interface: org.freedesktop.NetworkManager

          COMMAND := { status | list | disconnect | wifi }



              status

                     Print status of devices.  This is the default action, when no command is specified to dev object.

                     Reference to D-Bus:

                     No simple reference.



              list [iface <iface>]

                     Get detailed information about devices.  Without an argument, all devices are examined.  To get information for a specific device, iface argument with the interface name should be provided.

                     Reference to D-Bus:

                     No simple reference.



              disconnect iface <iface> [--nowait] [--timeout <timeout>]

                     Disconnect a device and prevent the device from automatically activating further connections without user/manual intervention.  --nowait option causes nmcli to exit immediately and not to wait

                     for command completion.  --timeout option provides a means to specify how long to wait for operation completion.

                     Reference to D-Bus:

                     interface: org.freedesktop.NetworkManager.Device

(END) 

List available connections:

nmcli con show

or

nmcli connection show

To edit a connection

nmcli con edit "connection name"

or

nmcli connection edit "connection name"

to set a static IP:

nmcli> set ipv4.addresses 192.168.1.100/24

nmcli> save

nmcli> quit

then restart the networkmanager.

You can check the configured IP through:

nmcli> print

To delete the IP address ( you should use it before adding a static IP , to avoid adding a multiple IPs):

nmcli> remove ipv4.addresses
