Procedure

1. Install the teamd and NetworkManager-team packages:

   # yum install teamd NetworkManager-team

Procedure

1. Create the team interface. For example, to create a team interface that uses the activebackup runner and both the interface and connection named team0, enter:

   # nmcli connection add type team con-name team0 ifname team0 team.runner activebackup

2. Optionally, set a link watcher. For example, to set the ethtool link watcher, modify the team0 connection:

   # nmcli connection modify team0 team.link-watchers "name=ethtool"

   Link watchers support different parameters. To set parameters for a link watcher, specify them space-separated in the name property. Note that the name property must be surrounded by quotes. For example, to use the ethtool link watcher and set its delay-up parameter to 2500 milliseconds (2.5 seconds):

   # nmcli connection modify team0 team.link-watchers "name=ethtool delay-up=2500"

   To set multiple link watchers and each of them with specific parameters, the link watchers must be separated by a comma. The following example sets the ethtool link watcher with the delay-up parameter and the arp_ping link watcher with the source-host and target-host parameter:

   # nmcli connection modify team0 team.link-watchers "name=ethtool delay-up=2, name=arp_ping source-host=192.0.2.1 target-host=192.0.2.2"

3. Configure the IPv4 settings. For example, to set a static IPv4 address, network mask, default gateway, DNS server, and DNS search domain the team0 connection, enter:

   # nmcli connection modify team0 ipv4.addresses '192.0.2.1/24'
   # nmcli connection modify team0 ipv4.gateway '192.0.2.254'
   # nmcli connection modify team0 ipv4.dns '192.0.2.253'
   # nmcli connection modify team0 ipv4.dns-search 'example.com'
   # nmcli connection modify team0 ipv4.method manual

4. Configure the IPv6 settings. For example, to set a static IPv6 address, network mask, default gateway, DNS server, and DNS search domain of the team0 connection, enter:

   # nmcli connection modify team0 ipv6.addresses '2001:db8::1/32'
   # nmcli connection modify team0 ipv6.gateway '2001:db8::fffe'
   # nmcli connection modify team0 ipv6.dns '2001:db8::fffd'
   # nmcli connection modify team0 ipv6.dns-search 'example.com'
   # nmcli connection modify team0 ipv6.method manual

5. Optionally, display the network interfaces, and note the names of the interfaces you want to add to the team in the next step:

   # nmcli device
   DEVICE  TYPE      STATE         CONNECTION
   enp1s0  ethernet  connected     enp1s0
   enp7s0  ethernet  disconnected  --
   enp8s0  ethernet  disconnected  --
   lo      loopback  unmanaged     --

   Important

   You can only use network interfaces in a team that are not assigned to any connection. In the above example, you can only use the enp7s0 and enp8s0 interfaces.

6. Assign the port interfaces to the team’s connection. For example, to add the interfaces named enp7s0 and enp8s0 to the team0 connection:

   # nmcli connection add type ethernet slave-type team con-name team0-port1 ifname enp7s0 master team0
   # nmcli connection add type ethernet slave-type team con-name team0-port2 ifname enp8s0 master team0

7. Activate the connection. For example, to activate the team0 connection:

   # nmcli connection up team0

8. Optionally, display the status of the team:

   # teamdctl team0 state
   setup:
     runner: activebackup
   ports:
     enp7s0
       link watches:
         link summary: up
         instance[link_watch_0]:
           name: ethtool
           link: up
           down count: 0
     enp8s0
       link watches:
         link summary: up
         instance[link_watch_0]:
           name: ethtool
           link: up
           down count: 0
   runner:
     active port: enp7s0

   In the example, both ports are up.

Procedure

1. Open a terminal, and enter nm-connection-editor:

   $ nm-connection-editor

2. Click the + button to add a new connection.
3. Select the Team connection type, and click Create.

4. On the Team tab:

   1. Optionally, set the name of the team interface in the Interface name field.

   2. Click the Add button to add a network interface as a slave to the team.

      1. Select the connection type of the interface. For example, select Ethernet for a wired connection.
      2. Optionally, set a connection name for the slave device.

      3. In the Device field on the Ethernet tab, select the network interface you want to add as a slave to the team.

         Important

         You can only use network interfaces in a team that are not configured.

      4. Click Save.

   3. Repeat the previous step for each interface you want to add to the team.

      

   4. Click the Advanced button to set advanced options to the team connection.

      1. On the Runner tab, select the runner.
      2. On the Link Watcher tab, set the link link watcher and its optional settings.
      3. Click OK.
5. On the IPv4 Settings tab, configure the IPv4 settings. For example, set a static IPv4 address, network mask, default gateway, DNS server, and DNS search domain:
6. On the IPv6 Settings tab, configure the IPv6 settings. For example, set a static IPv6 address, network mask, default gateway, DNS server, and DNS search domain:
7. Click Save to save the team connection.
8. Close nm-connection-editor.

9. Optionally, display the status of the team:

   # teamdctl team0 state
   setup:
     runner: activebackup
   ports:
     enp7s0
       link watches:
         link summary: up
         instance[link_watch_0]:
           name: ethtool
           link: up
           down count: 0
     enp8s0
       link watches:
         link summary: up
         instance[link_watch_0]:
           name: ethtool
           link: up
           down count: 0
   runner:
     active port: enp7s0
