Vlan will not work

alex6666 · 04-17-2008, 04:23 AM

I have one ethernetcard. I have one official ip on this and also want a tagged vlan on it. The official ip is working, but the tagged vlan does not work. Can you have both an untagged and a tagged vlan on one card?

The vlan is configured in ifcfg-vlan3 like this:

DEVICE=eth0.3
BOOTPROTO=static
BROADCAST=192.168.182.255
IPADDR=192.168.182.2
NETMASK=255.255.255.0
NETWORK=192.168.182.0
ONBOOT=yes
VLAN=yes

However this is not working. Any ideas why?

You need to change your interface file to ifcfg-eth0.3 ifcfg-vlan3 uses a different syntax

datopdog · 04-17-2008, 11:54 AM

this is the syntax for ifcfg-vlanX

Code:

VLAN=yes
VLAN_NAME_TYPE=VLAN_PLUS_VID_NO_PAD
DEVICE=vlan3
PHYSDEV=eth0
BOOTPROTO=static
ONBOOT=yes
TYPE=Ethernet
IPADDR=192.168.182.2
NETMASK=255.255.255.0

I have tried that, but it didn't work either. However when I tried using a second ethernetcard it worked fine.

I have heard that drivers for some cards do not support VLAN's

Hello!

I'm using Debian etch on a Dell PE1850 server with Intel PRO/1000 eth interface (eth0). I have to use some VLANs on this if.
1. I build a kernel supporting 802.1Q
2. I installed the package named vlan
3. I created VLANs (vconfig add eth0 800, ...)

But it doesn't work. I've sniffed the eth0 with wireshark but there is no vlan header betweeb Ethernet and IP header. I tried to set the flag to 0 but there was an error:

szvd:/proc/net/vlan# vconfig set_flag eth0.800 0
ERROR: trying to set flag on device -:eth0.800:- error: Invalid argument

I don't have mode idea..

What state is interface eth0 ? Please, post your ifconfig.

eth0 is up

Code:

szvd:~# ifconfig eth0
eth0      Link encap:Ethernet  HWaddr 00:11:43:D8:0D:F8
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1

I have got Debian Etch too. VLANs is working wonderful.

Code:

cat /proc/net/vlan/config
VLAN Dev name    | VLAN ID
Name-Type: VLAN_NAME_TYPE_PLUS_VID
vlan0002       | 2  | eth0
vlan0003       | 3  | eth0
vlan0004       | 4  | eth0
vlan0005       | 5  | eth0
vlan0006       | 6  | eth0
vlan0007       | 7  | eth0

I think problem in vlan's name. Try set other vlan name

Code:

vconfig set_name_type [name-type]
name-type:  VLAN_PLUS_VID (vlan0005), VLAN_PLUS_VID_NO_PAD (vlan5),
            DEV_PLUS_VID (eth0.0005), DEV_PLUS_VID_NO_PAD (eth0.5)
