Yes, it is.
on "freebsd 0 aka switch":
ifconfig bridge0 create
ifconfig em0.10 create #em0 port is patched to the "real" switch to a
trunk port configured to accept at least vlan 10
ifconfig em1 #this port is patched to "freebsd 1"
ifconfig em2 #this port is patched to "freebsd 2"
ifconfig bridge0 addm em0.10 addm em1 addm em2
up em0, em1, em2, em0.10, bridge0 interfaces and ports
em1 and em2 will be on vlan 10. If you run into trouble
run tcpdump -e on em0.

thankyou every body for your attention. yes bridging is done without ip
address. i try to use all the point which is mentioned here but my
problem is not solved yet.
you know i have three freebsd box. i wanna to config the intermediate
one as switch and two others as vlan member. i want to have just one
vlan and configure this vlan just on the switch (as a cisco switch) and
two other systems which are the member of this vlan, can ping each
other. is it possible? how?
the most important point for me is that i don't want to do any vlan
configuration on the vlan members. i want just configure switch system
to do it. in a real switch, we just define a vlan on the ports without
any configuration on the systems which are connected to these ports. i
exactly want to do this by a freebsd system as a switch. please tell me
if it is possible or not.
thank you so much

There are reports that hw assisted VLANs caused problems

i made a little lab, all on 8.2-R:
freebsd1-le0.10 (192.168.2.1)<=====> bridge0( le0.10 - freebsd2 -
le1.10 )<=====> le0.10(192.168.2.1) - freebsd3
freebsd2 is a "switch" it has no ip addresses assigned to interfaces
(except localhost of course), "switch" is made by bridge0 interface
which contain vlan interfaces le0.10 and le1.10. Ethernet segments
freebsd1-freebsd2 and freebsd2-freebsd3 are different and not
visible
to each other.
In this scheme i can ping 192.168.2.2 from 192.168.2.1 just fine, so
if your question was "will bridge work without ip addresses", then
answer is "yes".

you're right but we can't assign tow parent interface to one
vlan in freebsd
therefore i define two vlans with the one vlan id.
although we can do it by blow command but it's not work too:
ifconfig gbeth0.10 create
ifconfig msk0.10 create
ifconfig
gbeth0.10: flags=8842<BROADCAST,RUNNING,__SIMPLEX,MULTICAST>
metric 0 mtu 1500

options=100<TSO4>
ether 00:30:4f:63:5a:bc

you know when i define vlans with ip addressess they work as
i expected but
i want to know if i can define vlan without ip address as
the switch beacuse
i wanna configure a freebsd box as a real switch in my
network. maybe it's
impossible to do that :(

first of all, you should name and number you vlan same,
if it's clan10
on the one side, then it's vlan10 on the other side and
in betweeen.
then (though you have to do it first of all), you should
understand
how vlan's work, and after that connect ports to each
other according
to your scheme.

You probably just need to do ifconfig

hi every body
i wanna configure a freebsd box as a

i

real switch, a vlan is
configured
just
by assigning a port to it without
any additional configuration and
vlans
are submitted just by name. but in
freebsd a vlan just works when
it
has
an
ip address (i think). when i define
vlan121 on two freebsd systems
with
ip
address it works fine but without ip
address i don't know how it
should
be
worked.
can sombody tell me if it is
possible to simulate vlans in freebsd
as
they
are in a real switch? i mean can we
have vlans without ip
addresses
which
works fine? maybe some kind of vlan
which works by MAc address. is
it
possible?
it's so necessary for me to do that:(
