Hello misc@,
I decided to try out trunk(4) as shown in the last example of the
trunk(4) manual page; here is the related configuration:
[EMAIL PROTECTED] ~] cat /etc/hostname.iwn0
wpa wpapsk
0xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx nwid \
xxxx chan 1 media autoselect mode 11g
up
[EMAIL PROTECTED] ~] cat /etc/hostname.em0
lladdr 00:xx:xx:03:b1:59 up
[EMAIL PROTECTED] ~] cat /etc/hostname.trunk0
dhcp trunkproto failover trunkport em0 trunkport iwn0
rtsol
The scenario is that em0 is a master port and iwn0 is a failover port so
that when I am at my desk I use em0, and when I need to be mobile,
trunk0 switches to iwn0.
The problem is that when I boot up my laptop without cat5 plugged in
to the em0 (master), dhcp can't acquire the address; even though iwn0 is
connected. I assume that trunk0 must notice that status of em0 is 'no
carrier' and immediately switch to the 'active' iwn0 to acquire the lease.
In fact I tcpdump(8)ed both iwn0 and em0 while dhclient(8)ing trunk0, and
didn't see packets coming out of iwn0.
Note, I make sure both iwn0 and em0 have same lladdr in
order to make sure rtsol operates properly during IPV6 autoconf(I want
to make sure ipv6 connectivity remains intact if master port goes down).
I also tried without modified lladdr, and this mis-behavior didn't
change.
Other than this problem, everything works as expected. If laptop boots
up with em0 (master) plugged in, it properly acquires dhcp lease and
then works fine. If i take the cable out, trunk(0) immediately switches
to failover port and keeps operating properly.
I had a thought that it may be wpa related, but I tried the same
scenario with open Access Point, and nothing really changed.
here is the dmesg:
please excuse the 'GAMMA' kernel, it's just a GENERIC.MP + inteldrm
enabled.
