Network teaming allows combining multiple network interface cards (NICs) together for performance, redundancy, and higher throughput. The nmcli command can be used to configure network teaming by adding a team device, specifying the slave interfaces, and modifying properties like the IP address and autostart settings. The teamdctl command can check the state of the teaming configuration and interface and verify that traffic is flowing over the remaining NIC when one is disabled.

4. nmcli - command consept :
nmcli connection add con-name v_port type team ifname v_nic config
‘{“runner”: {“name”: “activebackup”}}’
nmcli connection add con-name port_1 type team-slave ifname ens7 master v_nic
nmcli connection add con-name port_2 type team-slave ifname ens8 master v_nic
+
=
con-name v_port
ifname v_nic
con-name port_1
ifname ens7
con-name port_2
ifname ens8

5. Full - nmcli command
 nmcli connection add con-name v_port type team ifname v_nic config
‘{“runner”: {“name”: “activebackup”}}’ - it’s jeson scripting
 nmcli connection modify v_port ipv4.addresses 10.0.0.2/24 - server ip
 nmcli connection modify v_port ipv4.method manual
 nmcli connection modify v_port connection.auotconnect yes
nmcli connection add con-name port_1 type team-slave ifname ens7 master v_nic
nmcli connection add con-name port_2 type team-slave ifname ens8 master v_nic
 S
ping 10.0.0.3 -I v_nic - remote ip

6. Checking Teaming configuration :
team d ctl = teaming demon control
teamdctl v_port state
ifdown ens7
ifdown ens8
teamdctl v_port state
ifup ens8
teamdctl v_port state
