To create a networking team using ifcfg files, create a file in the /etc/sysconfig/network-scripts/ directory as follows:

DEVICE=team0
DEVICETYPE=Team
ONBOOT=yes
BOOTPROTO=none
IPADDR=192.168.11.1
NETMASK=255.255.255.0
TEAM_CONFIG='{"runner": {"name": "activebackup"}, "link_watch": {"name": "ethtool"}}'

This creates the interface to the team, in other words, this is the master.

To create a port to be a member of team0, create one or more files in the /etc/sysconfig/network-scripts/ directory as follows:

DEVICE=eth1
HWADDR=D4:85:64:01:46:9E
DEVICETYPE=TeamPort
ONBOOT=yes
TEAM_MASTER=team0
TEAM_PORT_CONFIG='{"prio": 100}'

Add additional port interfaces similar to the above as required, changing the DEVICE and HWADDR field to match the ports (the network devices) being added. If port priority is not specified by prio it defaults to 0; it accepts negative and positive values in the range -32,767 to +32,767.

Specifying the hardware or MAC address using the HWADDR directive will influence the device naming procedure. This is explained in Chapter 8, Consistent Network Device Naming.

To bring up the network team, issue the following command as root:

~]# ifup team0

To view the network team, issue the following command:

~]$ ip link show
