Hello, I am creating a configuration where a Redhat server running bridge-tools 0.9.5 will be bridging between different VLANs on the same physical interface (for example: a bridge consisting of eth1.100 and eth1.110). This physical interface is being connected to modern Cisco switches running PVST+. The Cisco switch does not like this configuration as the tags on its BPDUs are being changed

Please bear with me as I know I have included a lot of detail. Description Redhat AS 3 Kernel 2.4.21-47.0.1.ELsmp eth0 HWaddr 00:07:E9:11:30:76 inet addr:192.168.1.3 Bcast:192.168.1.255 Mask:255.255.255.0 eth0:1 HWaddr 00:07:E9:11:30:76 inet addr:192.168.3.1 Bcast:192.168.3.255 Mask:255.255.255.0 This interface is up but with no IP address eth1

I''m looking for a way to shape all traffic on a virtual vlan interface, say eth1.100 to a max of 100mbit. The box is a quagga router with eth0 on the inside and vlan interfaces on the eth1 card to our upstream partners. Each partner has his own vlan on eth1. I tried shaping but was only able to shape outbound traffic on the eth1.100 interface. Inbound shaping was also possible, but

Hi all, I keep getting the following error messages on all my systems that have Vlans configured on it's ethernet interfaces.

Hi, I have a situation where router has to see hosts  in multiple vlans with the same IP address The test scenario is : --------------------- |  eth0 |     br0   | <-------> eth1.25 | eth1.26 | eth1.27 --------------------- eth0 = Internet br0 = Lan 192.168.100.1/24 host 1= 192.168.100.11/24 eth1.25 host 2= 192.168.100.12/24 eth1.26 I need br0 to see all hosts in all vlans

Hi all, I''m trying to put a linux GW running with this seput: Internet -> DSL Modem -> VLAN2 \ eth2.2 Linux > Lan eth2.3

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

Hi, I want to know maximum vlan can be created by openvswitch and linux-brigde. how can I test for this limit. Is there any tool. _______________________________________________ Xen-users mailing list Xen-users@lists.xen.org http://lists.xen.org/xen-users

I ran into an issue when trying to create VMs in CentOS 5.5 with VLANs. My setup is as follows: -CentOS 5.5 x64 xen kernel -LVM for storage -Kickstart file hosted on apache in /var/www/html/ -VM start file in /etc/xen/ -VLAN100 interface with public IP, VLAN200 interface with private IP My vm start file is as follows: kernel = "/boot/vm-inst/vmlinuz" ramdisk =

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

I have a strange problem with VLANs with Xen 3.0.4. I signalled it on Xen-users list, but found no definitive solution to it. I configure VLANs so that they are available in dom0; domUs don''t know that they use VLANs. I use a stock "network-bridge" comming from Xen for setting up networking: #!/bin/bash dir=$(dirname "$0") "$dir/network-bridge"

Hi, Setup info: (a) Using RHEL6 kvm. (b) Loaded driver on RHEL6 setup. (c) Created 2 bridges on top of two interfaces. (d) Assigned these bridges to 2 VMs. (e) Created vlans in VMs. Problem: When vlan acceleration support is enabled in driver, traffic stops b/w VMs on vlan interfaces inside virtual m/c. Without, vlan acceleration, everything works fine. Thanks, Sucheta.

Hello all, I'm trying to take advantage of libvirt's VLAN and OVS support in the 0.10.1 release and consistently getting an "error: internal error corrupted profileid string" when starting a guest. I've defined a network using virsh; the configuration looks like this: <network> <name>ovs-network</name>

So has anyone had any experience working with the polycom 501 or 301 and vlans? We run dell managed switches here, so we don't have the luxury of running CDP to force the VOIP vlan. I haven't been able to get the polycom phones to talk on a manually set vlan. I have some junky sipura phones that work fine-(get dhcp, register to asterisk etc) when i manually set them to vlan4. Any advice

Hi all How much does configuring a network with VLANs improve or effect quality ? Is there much reason to justify the configuration of VLANs ( I know networking, but not VLANs at all) Would it not be better to find high traffic users and determine why? Your Thoughts Thanks Barry

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

Hi All, I'm having some problems getting postfix to relay mail. I'd appreciate any tips. Perhaps there are some settings which I may have missed, somewhere. The postfix mail server is on VLAN 250 (192.168.250.0) whilst I have several other users on other VLANs (e.g. 91, 92, 93, etc... 192.168.91.0, 192.168.92.0, 192.168.93.0, etc...). So, if I had a PC sitting on VLAN 91 with IP

Has anyone setup FreeRadius to do automatic VLAN assignments on their switches based on client mac addresses? If so, would you be willing to share your radius configs? I haven't touched radius since mid 90's and am stuck trying to get this to work. It would be much appreciated. thanks -- -matt
