Hi there,
I'm trying to setup vlans on debian wheezy 7.6. But I can't get it to work.
Is there something special I'm missing out there? I tried searching around,
but I didn't get any further.
I couldn't figure out where this is going wrong. Looks like either the
packets going out the vlan is not being tagged, or something unknown is
happening.
I have 2 hosts directly connected to each other, both have intel i350Gb
ethernet cards.
host 1 physical interface eth1 = 10.0.10.68
host 2 physical interface has no ip, and vlan has assigned 10.0.10.70
When I ping ip address 10.0.10.68 through the vlan interface, I get no
response:
root@host2:~# ping 10.0.10.68 -c 1 -I eth1.10
PING 10.0.10.68 (10.0.10.68) from 10.0.10.70 eth1.10: 56(84) bytes of data.
>From 10.0.10.70 icmp_seq=1 Destination Host Unreachable
--- 10.0.10.68 ping statistics ---
1 packets transmitted, 0 received, +1 errors, 100% packet loss, time 0ms
I captured the packets on both machines on the physical iface with tcpdump,
and (both show the same with no reply to the request) :
root@host1:~# tcpdump -vv -i eth1 -s 1500 ether proto not 0x88cc
