Are there any new tools in CentOS 6 to configure VLAN interfaces (where the switch passes multiple tagged VLANs over one physical link to the host) or is it best to edit /etc/sysconfig/network-scripts/eth?.vlan# files manually? -- Les Mikesell lesmikesell at gmail.com

--- In english --- 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

<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

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

My actual scenario is: -Hundreds PCs in a internal network (fixed IP), divided in +- 6 different subnets -A +- 6 customers with leased lines -A Cisco Catalyst 4006 connecting groups of PCs to corresponding customers (imagine a Call Center company) -Works fine. The problem: Frequently, it''s necessary to migrate dozens PCs from a customer to another. You know, change all IPs and

I am using 8021q vlans on my servers, and I cannot figure out how to make PXE/DHCP work. Has anyone figured out how to do this ?

re can somebody tell me what am I doing wrong (at this late night hour), because vlan are not getting bridged at all. ifconfig eth0 0.0.0.0 up ifconfig eth1 0.0.0.0 up brctl addbr br0 brctl addif br0 eth0 brctl addif br0 eth1 ifconfig br0 up vconfig add br0 X vconfig add br0 Y X = vlan-ID (example: 222) Y = vlan ID (example: 223) # brctl show bridge name bridge

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 Eth1 -> Vlan

Hello. I''m trying to use vlan in domU, but have something strange: I created bridge on eth0. This interface was configured as trunk with vlan 300, 301. I use this bridge in my domU, and I can see tagged packets when run tcpdump in domU. Also I created interface on domU to work with vlan 300. On this interface I see untagged packets in vlan300. And everything looks fine. But when

Hi, I want to add 2 vlans by the following steps: 1. add the vlan interfaces: vconfig add eth0 100 --vlan100 vconfig add eth0 101 --vlan101 2. modify the network-bridge script by the websit, http://wiki.xensource.com/xenwiki/XenNetworking#head-04ebcc1760dbc4678e83b116afa310dc0612dc39 Comment each time ifup or ifdown commands are executed.The reason is that ifdown ends with

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

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

OK, strange request but I want to bridge three vlans under linux 2.4. Bridging works fine with two vlans, but is failing to route when I add the third vlan. Situation is clearly to have Lan, internet and DMZ vlans. The reason they are vlans is that I am using a Linksys WRT54GS and hence you effectively have a 5 port hub on the back which can be segregated into flexible vlan groups. I

We had problem using tagged vlans inside domU. Testing shows that this is caused by changing network interfaces in network-bridge script. Following patch should allow to use vlans in guest. Testing scenario: configure vlan network (e.g. vlan 1 on eth0 => eth0.1) start xend create domU and configure same vlan inside it You can see that vlan is still <interface>.<vlan_id>. You can

As the issue concerns both the -user (configuration) and -devel (OOPS), I''m sending this message to both lists. Some time ago I complained about two problems: - VLANs are not working on machines with 100 Mbit cards - I get a kernel Oops (sometimes panic) when I try to use bonding and VLANs with Xen The root of the issue is the same in both cases: VLAN interfaces must *not* be

Hello, I have a xen server that needs to run a domU on a different vlan than xen''s. I have configured my switch (a cisco catalyst) to tag every untagged packet to the default vlan (the one in which is dom0) and to accept tagged packets (for that domU). I have xenbr0 linked with the eth0, the default network. Then I run * vconfig add eth0 101 -> To create a virtual interface with

Hello, Is it possible with a linux Bow to route différents VLANs, like a router cisco can does ? Thank for your answers Laurent Foucher _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/

Hey gang, We have about 30 Cisco 79XX phones all running latest 7.5 SIP. We are also using all Cisco Switches and Routers. Everything works great except that when you reboot a phone it takes like 3-5 minutes for it to come up. The phones spend tons of time 'Configuring VLAN..' We don't run any VLANs. Is there some way to skip this? In the 'Network Settings' I have

hi, I have to configure Xen server and DomU''s which should be able to talk to different vlans - depending on services put on DomU''s. I would like to enslave 2 NICs via bond interface. Both NICs are on trunk ports which are configured in the same way, the same native vlan. I don''t know, if I have to add vlans tagging to eth* interfaces then enslave tagged eth*
