[Bridge] Bridging vlans...
<I apologize if this arrives twice... I sent it first from an
non-subscribed address, don't know if that'll get to the list or not --JJ>
Hi folks,
I have an implementation question regarding bridging on a linux box between
a catalyst trunk port and a cisco 26something w/802.1q subinterfaces.
So right now, there's no vlan trunking going on on the link my bridging
firewall sits

More complex Xen Networking, with VLANs and maybe with VDE 2... but how?!

Hello!
I am to implement a new architecture of the network in my company but I do
not know right where to start ... need help!
Currently 90% of my servers are virtual machines under Xen. I have many
valid IP networks and all Hypervisors are configured in bridge mode, to
simplify. We have 3 VMWare ESX Hypervisor also in bridge mode.
Some networks are exclusive to certain

Virtual switches
Hi,
[1]
Are there guides for setting up a virtual switch for use in between
guest domains in Xen ?
[2]
In Xen, is it possible for a guest domain to perform a initial dhcp IP
lookup from another guest domain ?
How are the configurations like ?
Are there references or step procedures ?
Kindly advice.
Thanks.

[Bridge] bridge, vlan and *no* stp/bpdu
Hello list,
I've posted here about this before, but I realise that it may have been
assumed that the bridged vlans simply put a switch port in a blocking
state and left my question ignored. So to recap.
I have two tg3 interfaces named 'in' and 'out' and a bridge named 'br0'
My vlan trunk is on the 'in' side of the network, and set as in.2, in.3

Problem with VLANs on tg3 NICs
I have 3 machines,
T60 thinkpad with e1000 NIC
Dell PowerEdge 2950 with bnx2 NIC
HP DL360 G4P with tg3 NIC
All running xen 3.03 / 2.6.16.29-xen
I have a netbootable image with 2.6.16.29-xenU. This image when it
boots creates a vlan eth0.4002, and then tries to communicate on that
interface to a central server.
On the machines with e1000 an bnx2 NICs, this works fine. On the

[Bridge] Transparently bridge Vlans to eth0
Hi,
I'm using Vlans in my network as a way of preventing
pier to pier communication - I only want nodes in the
network to talk to the gateway (a linux box).
I have successfully set up lots of sub interfaces
using the vconfig too, one for each vlan. What I would
like to be able to do is remove the ip address from
each of these subinterfaces eth0.x and bridge them to
eth0. I have successfully

How do I let vlan-tagged traffic go through a vlan bridge port and the
other traffic through a non-vlan bridge port?
Suppose eth0 and eth0.15 are ports of br0.

[Bridge] Re: Bridge Digest, Vol 31, Issue 6
Hello
You must add first:
vlan (tagged) to eth2
eth2 interface is not tagged by default and not know vlan-s .
It is like a cisco if you have 24 ports in cisco by default all ports
are in vlan1. if you want to do trunk (with vlans) you myst add (vlans)
to this ports (tagged or untagged)
So you can compare that all interfaces in linux by default are in one
vlan(but not tagged). (only for

Forwarding between untagged vlans
I''m trying to implement simple untagged vlans on our switch and have
misconfigured something..
ISP gw is on the default vlan1 (untagged)

eth1 is setup on the switch with default vlan1 and member of vlan4.
eth0 is default vlan4 which connects to the clients that are all
default members of vlan4
eth0 is x.x.x.86/28 This is what clients are connecting to as their gw..

Does anyone have VLAN tagging working from within a guest on vmware-server?
I'm running a centos 4.5 guest on a centos 5 host with vmware server

How to work with VLANs and several nic Interfaces ?
Hi all,
I have xen2.0.7 running in a fedora core 3 !
I have dom0 and domU running fine and communicating between each other as
well between other machines on diferent networks.
Still i want to improve my network setup and i start reading manuals and
malling lists about bridging and vlans configuration!
I have two nics each one associated to eth0 and eth1.
Eth0 -> Vlan A

VLAN issue
Andrew and Dennis are spot on.
Their conclusions about your server being connected to an access port and
not a trunk port would be my conclusion as well.

[Bridge] RFC: [PATCH] bridge vlan integration
Hi,
The attached patches enables the bridge to filter and forward packets
according to their IEEE 802.1q headers. The goals behind this change
include :
- Enable running STP on 802.1q tagged networks. STP packets
must be untagged. It isn't obvious how else to enable STP
with the current bridge and vlan code.
- Add native support for an untagged vlan. Currently an untagged

VLAN issue
Do you need the whole configuration? On the switch end, we have the
relevant VLAN (VLAN 48) with the assigned IP address of 192.168.48.101 and
the range of ports (Gi1/0/1 - Gi1/0/8) assigned to that VLAN.
Seems - and acts - like a legitimate setup and works fine, except for this
particular instance.
Thanks.
Boris.

VLAN issue
Thank you everyone.
OK, the mystery deepens, I guess. The machine does need to support several
VLAN's, it is currently on a trunkport (8021q encapsulated), it made it
into the ARP table - which I specifically tested for by physically
unplugging the table, clearing the ARP table and plugging it back in.
The ARP table currently looks like this:

Bonds, VLANs, and Bridges on Centos 5.6
Running on Centos 5.6 with KVM...
I was wondering if anyone had any luck configuring the NICs where eth0 and eth1 are bonded together with vlan support to a bridge?
I noticed some threads show this as a possibility (http://lists.centos.org/pipermail/centos-virt/2009-November/001417.html), but haven't had any luck implementing it. There also seems to be a bug with 5.6

hosted VMs, VLANs, and firewalld
I'm looking for some information regarding the interaction of KVM,
VLANs, firewalld, and the kernel's forwarding configuration. I would
appreciate input especially from anyone already running a similar
configuration in production. In short, I'm trying to figure out if
a current configuration is inadvertently opening up traffic across
network segments.
