I am working with VLANs and a BayStack 450-T without stability problems,
except when you configure NETGRAPH at the same time. The kernel crashes
during boot-up.

Subject: 802.1q vlans and STABLE
Hi,
are vlans and the fxp driver ready for prime time ? I have a situation
where I would like to deploy a simple network which looks like
[network vlan #1]-----[cat5500]-----[network vlan #2]
|
|
|
[freebsd fxp0]
The two remote networks would be trunked back to me using 802.1q encaps off
a cat 5500 switch. I am using the patch at
http://www.euitt.upm.es/~pjlobo/fbsdvlan.html
to account for larger frame sizes. Whats not clear to me is that when
configuring fxp0, do I just assign it IPs via the vlan interface, or should
I also give fxp0 a normal IP. Will it break things if fxp0 has an IP
associated with it ?
Also, does aliasing of vlan interfaces work as expected ?
if network #1 was 10.20.30.1/24 and 10.30.40.1/24 on vlan #123
and
network #2 was 172.16.1.1/24 and 192.168.1.1/24 on vlan #456
do I just do
ifconfig fxp0 up
ifconfig vlan0 inet 10.20.30.1 netmask 255.255.255.0 vlan 123 vlandev fxp0
mtu 1500
ifconfig vlan0 inet 10.30.40.1 netmask 255.255.255.0 alias
ifconfig vlan1 ....
Is there a limit as to the # of vlan interfaces ? Also, do I have any
performance hits if I have too many vlans ? If I recall correctly, in
LINUX, there used to be a performance hit if you had too many interfaces.
