[VLAN] problem with basic topology

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,
I'm trying to implement the following very basic topology:


box A:                        box B:
_______ eth0           eth0 _______
|          |_ _ _trunk _ _ _|           |
|______|                      |_______|

Both ethernetcards are 'PWLA8391GT (intel pro/1000 gt desktop adapter)'. 
The 'e1000' driver is used on both computers.
The trunk is a crossover-cable connecting the two nics directly.

Box A is runing debian etch(2.6.16-2-amd64-k8-smp)  and has been 
configured with the following configuration:

 ip link set up dev eth0
 modprobe 8021q
 vconfig set_name_type VLAN_PLUS_VID_NO_PAD

 vconfig add eth0 2
 ip addr add dev vlan2 10.10.2.2/24 broadcast 10.10.2.255
 ip link set dev vlan2 up

 vconfig add eth0 3
 ip addr add dev vlan3 10.10.3.2/24 broadcast 10.10.3.255
 ip link set dev vlan3 up

 vconfig add eth0 4
 ip addr add dev vlan4 10.10.4.2/24 broadcast 10.10.4.255
 ip link set dev vlan4 up

 ip route add default via 10.10.2.1

Box B is running debian sarge(2.6.15-1-686) and has been configured with 
the following configuration:

 ip link set up dev eth0
 modprobe 8021q
 vconfig set_name_type VLAN_PLUS_VID_NO_PAD

 vconfig add eth0 2
 ip addr add dev vlan2 10.10.2.1/24 broadcast 10.10.2.255
 ip link set dev vlan2 up

 vconfig add eth0 3
 ip addr add dev vlan3 10.10.3.1/24 broadcast 10.10.3.255
 ip link set dev vlan3 up

 vconfig add eth0 4
 ip addr add dev vlan4 10.10.4.1/24 broadcast 10.10.4.255
 ip link set dev vlan4 up


If I test the nics without  vlan they work perfectly. If I use them with 
the above mentioned conf then eth0 on box a won't recive anything while 
eth0 on box b is able to both transmitt and recive.


I did the following test:

on box a:

PING 10.10.2.1 (10.10.2.1) 56(84) bytes of data.
 From 10.10.2.2 icmp_seq=1 Destination Host Unreachable

22:48:38.087740 arp who-has 10.10.2.1 tell 10.10.2.2

on box b:

tcpdump: WARNING: eth0: no IPv4 address assigned

22:52:14.076104 arp who-has 10.10.2.1 tell 10.10.2.2

If I do a 'cat /proc/net/dev' on box b I can see that data is being 
recived and transmitted on eth0 and vlan2 .
If I do a ' cat /proc/net/dev' on box a I can only see data being 
transmitted on eth0 and eth2. There is no reciveing and no dropping of 
packages on the same interfaces. I have tested with another 
crossover-cable: same result. I have tried also to assign static macaddr 
in the arp table on both computers but  eth0  on  box a still wont 
recive anything.


Anybody got any ideas on what I am doing wrong?



Best Regards

Andreas
