[Madwifi-users] 802.1Q vlans

[Raimonds M. <rai...@dt...>]

may be anyone have answer..

i try to setup vlans through wireless links.

node A:
iwpriv ath0 mode 1
iwconfig ath0 mode master
ifconfig eth0 0
vconfig add ath0 3
ifconfig ath0.3 192.168.0.1 netmask 255.255.255.0

node B:
iwpriv ath0 mode 1
iwconfig ath0 mode managed
ifconfig eth0 0
vconfig add ath0 3
ifconfig ath0.3 192.168.0.2 netmask 255.255.255.0

from node A:
ping 192.168.0.2 -c 1

then listen on node A and B with tcpdump on ath0 interface.
17:43:02.534167 00:04:75:da:47:ee > ff:ff:ff:ff:ff:ff, ethertype 802.1Q
(0x8100), length 60: vlan 4, p 0, ethertype ARP, arp who-has 192.168.0.2
tell 192.168.0.1
17:43:02.534448 00:01:24:70:52:17 > 00:04:75:da:47:ee, ethertype ARP
(0x0806), length 42: arp reply 192.168.0.2 is-at 00:01:24:70:52:17

arp replays are going back without vlan's tags.

when i set mac address manually with interface parameter:
arp -s 192.168.0.1 00:04:75:da:47:ee -i ath0.4 # on node B
arp -s 192.168.0.2 00:01:24:70:52:17 -i ath0.4 # on node A
then all are ok. traafic is going via tagged interfaces.

i m using many vlans with wired devices, but newer see nothing similarly.

why?
what there is wrong?
