NAME
brctl - ethernet bridge administration
SYNOPSIS
brctl [command]
DESCRIPTION
brctl is used to set up, maintain, and inspect the ethernet bridge con-
figuration in the linux kernel.
An ethernet bridge is a device commonly used to connect different net-
works of ethernets together, so that these ethernets will appear as one
ethernet to the participants.
Each of the ethernets being connected corresponds to one physical
interface in the bridge. These individual ethernets are bundled into
one bigger ('logical') ethernet, this bigger ethernet corresponds to
the bridge network interface.
INSTANCES
The command brctl addbr <name> creates a new instance of the ethernet
bridge. The network interface corresponding to the bridge will be
called <name>.
The command brctl delbr <name> deletes the instance <name> of the eth-
ernet bridge. The network interface corresponding to the bridge must be
down before it can be deleted!
The command brctl show shows all current instances of the ethernet
bridge.
