CentOS 7 through nmcli team to achieve multiple network card binding
nmcli con add type team con-name team0 ifname team0 config ‘{“runner”:{“name”:”roundrobin”}}’
Run ip link command to view the interface available in the system
1, create a bond card
nmcli con add type team con-name team0 ifname team0 config ‘{ “runner”: { “name”: “roundrobin”}}’
various modes:
the METHOD is One of the following: broadcast, activebackup, roundrobin, loadbalance, or lacp.
The first mode: mod = 0, namely: (balance-rr) Round-robin policy Switch configuration Eth-Trunk
The second mode: mod = 1, namely: policy The
third mode: mod = 2, namely: (balance-xor) XOR policy The
fourth mode: mod = 3, namely: broadcast The
fifth mode: mod = 4, namely: (802.3ad) IEEE 802.3ad Dynamic link aggregation
Sixth mode: mod = 5, namely: balance-tlb Adaptive transmit load balancing:
The seventh mode: mod = 6, namely: (balance-alb) Adaptive load balancing (adapter adaptable load balancing)
2, view the creation of the network card
nmcli con show
3, add the load of the network card
nmcli con add type team-slave con-name team0-port1 ifname em1 master team0
nmcli con add type team-slave con-name team0-prot2 ifname em4 master team0
4. Configure IP address and gateway
nmcli con mod team0 ipv4.addresses “171.16 .41.x / 24 ”
nmcli con mod team0 ipv4.gateway” 171.15.41.x ”
nmcli con mod team0 ipv4.method manual
nmcli con up team0
5, restart the network service
systemctl restart network
6, check the network card binding status
teamdctl team0 state
7, check NIC binding
nmcli dev dis em1 / / closed binding state
nmcli dev con em1 / / restore the binding state
