RHEL \/ CentOS 7 Network Teaming<\/p>\n
Below is an example on how to configure network teaming on RHEL\/CentOS 7. It is assumed that you have at least two interface cards.<\/p>\n
Show Current Network Interfaces
\n[root@rhce-server ~]$ ip link
\n1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT
\nlink\/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
\n2: eno16777736: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT qlen 1000
\nlink\/ether 00:0c:29:69:bf:87 brd ff:ff:ff:ff:ff:ff
\n3: eno33554984: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT qlen 1000
\nlink\/ether 00:0c:29:69:bf:91 brd ff:ff:ff:ff:ff:ff<\/p>\n
The two devices I will be teaming are eno33554984 and eno16777736.<\/p>\n
Create the Team Interface
\n[root@rhce-server ~]$ nmcli connection add type team con-name team0 ifname team0 config ‘{“runner”: {“name”: “activebackup”}}’<\/p>\n
This will configure the interface for activebackup. Other runners include broadcast, roundrobin, loadbalance, and lacp.<\/p>\n
Configure team0\u2019s IP Address
\n[root@rhce-server ~]# nmcli connection modify team0 ipv4.addresses 192.168.1.22\/24
\n[root@rhce-server ~]# nmcli connection modify team0 ipv4.method manual<\/p>\n
You can also configure IPv6 address by setting the ipv6.addresses field.<\/p>\n
Configure the Team Slaves
\n[root@rhce-server ~]# nmcli connection add type team-slave con-name team0-slave1 ifname eno33554984 master team0
\nConnection ‘team0-slave1’ (4167ea50-7d3a-4024-98e1-3058a4dcf0fa) successfully added.
\n[root@rhce-server ~]# nmcli connection add type team-slave con-name team0-slave2 ifname eno16777736 master team0
\nConnection ‘team0-slave2’ (d5ed65d1-16a7-4bc7-8c4d-78e17a1ed8b3) successfully added.<\/p>\n
Check the Connection
\n[root@rhce-server ~]# teamdctl team0 state
\nsetup:
\nrunner: activebackup
\nports:
\neno16777736
\nlink watches:
\nlink summary: up
\ninstance[link_watch_0]:
\nname: ethtool
\nlink: up
\neno33554984
\nlink watches:
\nlink summary: up
\ninstance[link_watch_0]:
\nname: ethtool
\nlink: up
\nrunner:
\nactive port: eno16777736<\/p>\n
[root@rhce-server ~]# ping -I team0 192.168.1.1
\nPING 192.168.1.1 (192.168.1.1) from 192.168.1.24 team0: 56(84) bytes of data.
\n64 bytes from 192.168.1.1: icmp_seq=1 ttl=64 time=1.38 ms
\n…<\/p>\n
Test Failover
\n[root@rhce-server ~]# nmcli device disconnect eno16777736
\n[root@rhce-server ~]# teamdctl team0 state
\nsetup:
\nrunner: activebackup
\nports:
