To swap or change the aliases of Ethernet interfaces on a Red Hat or CentOS Linux system, you can use the ip command.
First, use the ip link command to list the available Ethernet interfaces and their aliases:
ip link
This will display a list of the available Ethernet interfaces, along with their interface names and aliases.
To change the alias of an interface, use the ip link command with the set option and the name option. For example, to change the alias of the interface eth0 to new_alias, you can use the following command:
ip link set eth0 name new_alias
This will change the alias of eth0 to new_alias.
You can also use the ifrename command to change the alias of an interface. For example:
ifrename eth0 new_alias
It's always a good idea to carefully review the documentation and use the appropriate commands to change the aliases of Ethernet interfaces on your system. This can be useful in cases where you need to customize the interface names for your network configuration.
