Network teaming

Creating Script to add team using man:

man nmcli-examples |grep “Example 7″ -A 4|tail -n3|cut -d “$” -f 2 > a.sh
vi a.sh
nmcli con add type team con-name Team1 ifname Team1 config team1-master-json.conf
nmcli con add type team-slave con-name Team1-slave1 ifname em1 master Team1
nmcli con add type team-slave con-name Team1-slave2 ifname em2 master Team1
Replace em1 and em2 with your_interface1 and your_interface1 in above example. And, replace team1-master-json.conf, with ‘{“runner”:{“name”,”activebackup”}}’ in above below. If you don’t want activebackup, you can replace activebackup with other types of team.

If you just want to see man help for team use following line:

man nmcli-examples |grep “Example 7″ -A 4


Steps involved: (ens9 and ens10 are interfaces in my case)

1. Create team:
nmcli connection add type team con-name team0 ifname team0 config ‘{“runner”:”name”:”activebackup”}}’

2. Assign IPv4 address and gateway. Note: in exam you may not need to assign gatway for team inerface.
nmcli  con mod team0 ipv4.method manual ipv4.addresses “10.0.0.100/24 10.0.0.1″
3. Assign ens9 interface to team0 as slave
nmcli connection add type team-slave con-name team0-ens9 ifname ens9 master team0

4. Assign ens10 interface to team0 as slave
nmcli connection add type team-slave con-name team0ens10 ifname ens10 master team0

5. Getting up team0 connection
nmcli connection up team0

7 Verifying team status
teamdctl team0 state
teamnl team0 ports

8. Verifying team stating by shutting down ens9 and ens10 one by one.
nmcli con dis ens9
teamdctl team0 state
