brctl(8)

NAME
brctl - Bridge and Spanning Tree Protocol administration.
SYNOPSIS
brctl [options]
DESCRIPTION
brctl is used to set up, maintain, and display the bridge configuration in the Linux kernel.
brctl is a standard command included with Linux bridge support including Rapid Spanning
Tree Protocol (RSTP).
A bridge is a device commonly used to connect different networks together, so that these
networks will appear as one network to the participants.
Each of the networks being connected corresponds to one physical interface, or port in the bridge.
These individual networks are bundled into one bigger logical network. This bigger network
corresponds to the bridge network interface.
Multiple bridges can work together to create even larger networks using the IEEE 802.1d
Spanning Tree Protocol. This protocol is used for finding the shortest path between two networks
as well as eliminating loops from the topology. Bridges communicate with each other by sending
and receiving Bridge Protocol Data Units (BPDUs).
brctl(8) can be used for configuring certain spanning tree protocol parameters. For an
explanation of these parameters, see the IEEE 802.1d specification for detailed information.
OPTIONS
addbr
creates a new instance of a bridge. The network interface
corresponding to the bridge will be called <bridge>. For the
OpenArchitect switch, bridges are named bzhp0, bzhp1, etc.
IMPORTANT: This option must only be executed by zl2d.
delbr
deletes the instance <bridge> of an Ethernet bridge. The network
interface corresponding to the bridge must be down before it can
be deleted.
IMPORTANT: This option must only be executed by zl2d.
show shows all current bridges.
