RHCE Study Notes (30)-Converged network

This section focuses on how to configure the converged network (NIC Teaming) and Bridging Network (bridge)

The configuration and Ipv4,ipv6 of NIC Teaming and bridged networks are not much different and still can be modified by similar GUI, command line and configuration files.

NIC teaming, simply said, is that multiple physical ports are bundled together as a logical port for increased bandwidth, load balancing, or high-availability functionality. RHEL7 inside is through runner (can be regarded as a piece of code) to achieve different purposes.

See below How to configure NIC Teaming

Redhat official documentation gives 5 ways to configure, beans are more accustomed to command line binding configuration file to modify.

The basic process of configuration is to configure a connection to a logical port, as master, and then configure the required physical port as a slave connection and bind to the group. The logical port is then assigned the IP to use.

For example

I now have 2 network cards, they have different MAC addresses, configure NIC teaming before I go to their existing connections are deleted;

Then to create a group, the bean configuration when not reading, but also remember the command parameters, so through the TAB key can constantly remind me what the next parameter can be.

Configuration of the time forgot to set config, then the default is empty, how to do, modify it

Modified the contents of Config

Restart try, eh error?!!

Take a look at the configuration file directly what's going on, old place.

In config there, you need to add a single quotation mark before and after, or there is a problem with the compilation. The beans, by the way, changed the loadbalance to active backup, otherwise the test was not obvious.

Don't forget to make sure the connection is connected if it's not connected.

And then restart the network, then there's no problem.

See the current connection

Look at the ifconfig and find that the address of the NIC is the same so that the switch can transfer the packet to the same logical port

Finally, don't forget to assign an IP address to team0, where the beans are directly modified with the graphical tool

Test it, first look at the current state

Turn off the ENO connection, switch to the second physical port automatically, and test successfully.
