On a Linux system, an Ethernet bridge is a device that allows multiple network interfaces to be connected and treated as a single network. Ethernet bridges are often used to connect multiple devices or networks together, or to allow a device to act as a router or gateway.
To display the Ethernet bridge name and information on a Linux system, you can use the brctl command. brctl is a utility that is used to configure and manage Ethernet bridges.
Here's an example of how to use brctl to display the Ethernet bridge name and information:
$ brctl show
This will display a list of the Ethernet bridges on the system, along with their names and information.
For example, the output might look something like this:
bridge name bridge id STP enabled interfaces br0 8000.001517c7eba no eth0 eth1 br1 8000.001b3c3c3e4e no eth2 eth3
This indicates that the system has two Ethernet bridges (br0 and br1), each with two interfaces (eth0 and eth1 for br0, and eth2 and eth3 for br1).
Note: The specific options and syntax for the
brctlcommand may vary depending on your Linux distribution and version. Consult thebrctlman page or documentation for your system for more information.
It's also worth noting that Ethernet bridges can be configured and managed using the ip command, which is part of the iproute2 suite of utilities. The ip command can be used to display information about the bridges on the system, as well as to add or delete interfaces from a bridge, set bridge options, and more.
