|
||||
.Sh DESCRIPTION
|
||||
The
|
||||
.Nm
|
||||
utility is used to configure network bridge parameters and retrieve
|
||||
network bridge parameters and status from the kernel. The bridging
|
||||
function is implemented by the
|
||||
.Xr bridge 4
|
||||
driver.
|
||||
.Pp
|
||||
A network bridge creates a logical link between two or more
|
||||
IEEE 802 networks that use the same (or
|
||||
.Dq similar enough )
|
||||
framing format. For example, it is possible to bridge Ethernet
|
||||
and 802.11 networks together, but it is not possible to bridge
|
||||
Ethernet and Token Ring together.
|
||||
.Pp
|
||||
Bridge interfaces are created using the
|
||||
.Xr ifconfig 8
|
||||
command's
|
||||
.Dq create
|
||||
sub-command. All other bridge configuration is performed using
|
||||
.Nm "" .
|
||||
.Pp
|
||||
The options are as follows:
|
||||
.Bl -tag -width indent
|
||||
.It Fl a
|
||||
Display the status of all bridge devices present on the system. This
|
||||
flag is mutually exclusive with all other sub-commands.
|
||||
.El
|
||||
.Pp
|
||||
All other operations require that a bridge be specified. If a
|
||||
bridge is specified with no sub-commands, the status of that bridge
|
||||
is displayed. The following sub-commands are available:
|
||||
.Pp
|
||||
.Bl -tag -width indent
|
||||
.It Cm up
|
||||
Start forwarding packets on the bridge.
|
||||
.It Cm down
|
||||
Stop forwarding packets on the bridge.
|
||||
.It Cm add Ar interface
|
||||
Add the interface named by
|
||||
.Ar interface
|
||||
as a member of the bridge. The interface is put into promiscuous mode
|
||||
so that it can receive every packet sent on the network.
|
||||
.It Cm delete Ar interface
|
||||
Remove the interface named by
|
||||
.Ar interface
|
||||
from the bridge. Promiscuous mode is disabled on the interface when
|
||||
it is removed from the bridge.
|
||||
.It Cm maxaddr Ar size
|
||||
Set the size of the bridge address cache to
|
||||
.Ar size .
|
||||
The default is 100 entries.
|
||||
.It Cm timeout Ar seconds
|
||||
Set the timeout of address cache entries to
|
||||
.Ar seconds
|
||||
seconds. If
|
||||
.Ar seconds
|
||||
is zero, then address cache entries will not be expired. The
|
||||
default is 240 seconds.
|
||||
.It Cm deladdr Ar address
|
||||
Delete
|
||||
.Ar address
|
||||
from the address cache.
|
||||
.It Cm flush
|
||||
Delete all dynamically-learned addresses from the address cache.
|
||||
.It Cm flushall
|
||||
Delete all addresses, including static addresses, from the address cache.
|
||||
.It Cm discover Ar interface
|
||||
Mark an interface as a
|
||||
.Dq discovering
|
||||
interface. When the bridge has no
|
||||
address cache entry (either dynamic or static) for the destination address
|
||||
of a packet, the bridge will forward the packet to all member interfaces
|
||||
marked as
|
||||
.Dq discovering .
|
||||
This is the default for all interfaces added to a bridge.
|
||||
.It Cm -discover Ar interface
|
||||
Clear the
|
||||
.Dq discovering
|
||||
attribute on a member interface. For packets without the
|
||||
.Dq discovering
|
||||
attribute, the only packets forwarded on the interface are broadcast
|
||||
or multicast packets and packets for which the destination address
|
||||
is known to be on the interface's segment.
|
||||
.It Cm learn Ar interface
|
||||
Mark an interface as a
|
||||
.Dq learning
|
||||
interface. When a packet arrives on such an interface, the source
|
||||
address of the packet is entered into the address cache as being a
|
||||
destination address on the interface's segment. This is the default
|
||||
for all interfaces added to a bridge.
|
||||
.It Cm -learn Ar interface
|
||||
Clear the
|
||||
.Dq learning
|
||||
attribute on a member interface.
|
||||
.It Cm stp Ar interface
|
||||
Enable Spanning Tree protocol on
|
||||
.Ar interface .
|
||||
The
|
||||
.Xr bridge 4
|
||||
driver has support for the IEEE 802.1D Spanning Tree protocol (STP).
|
||||
Spanning Tree is used to detect and remove loops in a network topology.
|
||||
.It Cm -stp Ar interface
|
||||
Disable Spanning Tree protocol on
|
||||
.Ar interface .
|
||||
This is the default for all interfaces added to a bridge.
|
||||
.It Cm maxage Ar seconds
|
||||
Set the time that a Spanning Tree protocol configuration is valid. The
|
||||
default is 20 seconds. The mininum is 1 second and the maximum is 255
|
||||
seconds.
|
||||
.It Cm fwddelay Ar seconds
|
||||
Set the time that must pass before an interface begins forwarding
|
||||
packets when Spanning Tree is enabled. The default is 15 seconds. The
|
||||
mininum is 1 second and the maximum is 255 seconds.
|
||||
.It Cm hellotime Ar seconds
|
||||
Set the time between broadcasting of Spanning Tree protocol
|
||||
configuration messages. The default is 2 seconds. The minimum is 1
|
||||
second and the maximum is 255 seconds.
|
||||
.It Cm priority Ar value
|
||||
Set the bridge priority for Spanning Tree. The default is 32768.
|
||||
The minimum is 0 and the maximum is 65536.
|
||||
.It Cm ifpriority Ar interface Ar value
|
||||
Set the Spanning Tree priority of
|
||||
.Ar interface
|
||||
to
|
||||
.Ar value .
|
||||
The default is 128. The minimum is 0 and the maximum is 255.
|
||||
.El
|
||||
.Sh EXAMPLES
|
||||
The following then placed in the file
|
||||
.Pa /etc/ifconfig.bridge0
|
||||
will cause the a bridge called
|
||||
.Sq bridge0
|
||||
to be created, and will add the interfaces
|
||||
.Sq ray0
|
||||
and
|
||||
.Sq fxp0
|
||||
to the bridge, and then enable packet forwarding. Such a
|
||||
configuration could be used to implement a simple
|
||||
802.11-to-Ethernet bridge (assuming the 802.11 interface is
|
||||
in ad-hoc mode).

|
||||
Consider a system with two 4-port Ethernet boards. The following
|
||||
placed in the file
|
||||
.Pa /etc/ifconfig.bridge0
|
||||
will cause a bridge consisting of all 8 ports with Spanning Tree
|
||||
enabled to be created:
|
||||
.Bd -literal -offset indent
|
||||
create
|
||||
!brconfig $int \e
|
||||
add tlp0 stp tlp0 \e
|
||||
add tlp1 stp tlp1 \e
|
||||
add tlp2 stp tlp2 \e
|
||||
add tlp3 stp tlp3 \e
|
||||
add tlp4 stp tlp4 \e
|
||||
add tlp5 stp tlp5 \e
|
||||
add tlp6 stp tlp6 \e
|
||||
add tlp7 stp tlp7 \e
