Available Runners and configuring teaming interface

Last Blog Review →

In the last blog we understood, what is NIC teaming

What are Runners →

This are distinct unit of implement NIC teaming in different mode.

Available Runners in NIC →

1. broadcast → data is transmitted all over ports

2. active-backup → one port or link is used while others are kept as a backup

3. round-robin → data is transmitted over all ports in turn

4. loadbalance → Traffic is distributed across all NIC’s

Advantage of NIC Teaming →

1. Load balancing →

   In case of NIC Teaming, the network traffic is balanced across all active NIC’s equally.

2. Fault Tolerance →

   Another benefit offered by NIC Teaming is higher Fault Tolerance. If one of the underlying physical NICs is broken down or if the cable of the corresponding NIC is unplugged, the host/server detects the fault condition and moves the traffic to another NIC automatically. This reduces the possibility of a breakdown of the entire network, thus improving the fault tolerance of the system.

cmd’s for teaming interface.

1. configure network teaming domain

    yum install teamd
   

2. create the teaming interface

    nmcli con add type team con-name Teama ifname Teama config
    '{"runner": {"name": "activebackup"}}'
   

3. Add an IPv4 configuration

    nmcli con modify Team1 ipv4.add 192.168.1.10/24 gw4 192.168.1.1 
    ipv4.dns 192.168.1.1 connection.autoconnect yes ipv4.method manual
   

4. Add the eth0 & eth1 interface to the teaming interface

    nmcli con add type team-slave con-name Teama-slavea ifname enp0s1 master Teama
   
    nmcli con add type team-slave con-name Teama-slave2 ifname enp0s2 master Teama
   

5. Activating the teaming interface

    nmcli con up Teama
    nmcli con up Teama-slave1
    nmcli con up Teama-slave2
   

   For checking

    ping 192.168.1.10
    teamdctl Teama stat
   

Conclusion

In the this blog we understood, what are runners, types of runners and advantages of runners. Commands of network interface teaming.
