To display information about Ethernet bridges on a Linux system, you can use the brctl command. This command is used to configure and manage Ethernet bridges on the system.
To display information about the Ethernet bridges on the system, you can use the following command:
brctl show
This will show information about each bridge, including the bridge name, the interfaces it is attached to, and the status of each interface. The output of this command will look similar to this:
bridge name bridge id STP enabled interfaces
br0 8000.001b67d3a3f1 no eth0
eth1
In this example, the output shows that there is one bridge named “br0”, and it has two interfaces attached to it, “eth0” and “eth1”. The bridge is not using the Spanning Tree Protocol (STP).
