The following parameters are specific to bridge interfaces:
|
||||
.Bl -tag -width indent
|
||||
.It Cm addm 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 deletem 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 if_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 minimum 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 minimum 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.
