Link aggregation, teaming
Pre-requisite
- Add at least three network interfaces to your system like enp0s,8, 9, and 10
1. Check device status
# nmcli device status
2. Create Team master interface using Network Manager with type team.
# nmcli con add con-name team0 type team ifname team0 config '{"runner": {"name": "loadbalance"}}'
3. Create Team slave interfaces and attach to your Team master.
# nmcli con add con-name team0-p01 type team-slave ifname enp0s8 master team0
# nmcli con add con-name team0-p02 type team-slave ifname enp0s3 master team0
4. Modify team0 interface and assign an ipv4 address
# nmcli con mod team0 ipv4.addresses 192.168.1.153/24
# nmcli con mod team0 ipv4.method manual
# nmcli con mod team0 team.config '{"runner": "name": "activebackup"}}'
6. Check the team configuration with teamdctl.
# teamdctl team0 state
Note: Since bridging does not work using Network Manager, you have to shutdown the team0 interface, stop and disable Network Manager.
# nmcli con down team0
# nmcli stop NetworkManager
# nmcli disable NetworkManager
Edit the team0 interface configuration file and add the BRIDGE=brteam0 name pair.
# vi /etc/sysconfig/network-scripts/ifcfg-team0
BRIDGE=brteam0
