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
brctl
command may vary depending on your Linux distribution and version. Consult thebrctl
man 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.
