similar to: Guest vlan trunk port networking issues

Hi, I've set up a virtual machine and plugged it into a bridge on the host. When i configure an ip for eth0 in the guest i can ping other machines fine but when I add an interface eth0.10 in the guest and add an ip pings using this interface do not work. When using tcpdump in vnet0 on the host I can see the icmp packets when I ping using eth0 in the guest but not when I use the eth0.10

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. On Fri, Jan 23, 2015 at 8:54 PM, Dennis Jacobfeuerborn < dennisml at

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.

Hi Boris, what I'd like to know is the actual VLAN configuration of the switch port (link-type and tagged and untagged VLANs). When I look at the switchport coniguration here I get (among other things): ... Port link-type: trunk Tagged VLAN ID : 8, 1624 Untagged VLAN ID : 10 ... Here is my suspicion: Your ports have an access link-type with an untagged VLAN ID of 48. That would

Hi all, I''m sure I''m soing something wrong here. I am trying to set up a rate limit inside another rate limit. eg. I have a 512K rate limit on a particular VLAN. I am using an IFB so that packets passing through the bridge are counted at each port.(ie the throughput is limited to 512K, not just the traffic in one direction.) This part works OK, but I also want to limit a

OK... but why does it need to be a trunk port? Boris.

Hi all, I'm currently in the process of building a 2-Node libvirt/KVM Cluster and ran into some issues regarding the network connectivity of our virtual machines. Our setup seemed to work fine, we were able to browse to Google and our own company website and some others from within the VM. Then we tried microsoft.com to download some Windows iso images from MS Partner Network. The page

Hi, I ran into a Problem when using alias interfaces with vlans on a centos 5 box. When I define such an interface and do a "service network restart" the alias interface doesn't get started. Starting it manually works fine. Also after changing DEVICE=eth0.10:0 to DEVICE=eth0:0 in the config file the interface is started after a network restart. Does anyone have an idea what the

A VLAN is basically a 4 byte "tag" that gets injected into the packet header when the packet enters the VLAN network. When we trunk a VLAN we say to the switch "pass packets on VLAN x but

Steve, Thanks, makes sense. I just don't see why I have to effectively waste an extra IP address to get my connection established. Boris.

Hi I have problems with shaping traffic running through a VLAN. I have done the following set up: I have a linux box a gateway. I wish to use VLAN on the internal interface (eth0). eth1 is connected to the internet. I will like to be able to shape the dowstream traffic. I have set up the followingon the gateway: vconfig add eth0 10 tc qdisc add dev eth0.10 parent root handle 1: htb default 2

I figured I should post this because before I went to do it I searched the web for caveats etc and didn''t really find much. So anyway, I set up bonding + vlan for a project. Computer is dell powerdge 350 with 2 intel 82559 10/100 nic running stock 2.4.20. I tried both the eepro100 and the e100 drivers for the nics, both work 802.1q and bonding are modules. Switch is cisco 2924xl-en

Maybe my google-fu is failing me, but I have spent the past couple hours looking at how to add a vnet? Device to my KVM host running CentOS 6, and for the life of me I can't get this going. >From all my research if I want to add a device I should just do 'brctl addif br1 vnet14' if I want to add a vnet14 to bridge br1. When I do this, I get: # brctl addif br0 vnet14

Hi guys, I saw this sub-element in http://libvirt.org/firewall.html, there is some confusion, what's the meaning of sub-element <ip address='X.X.X.X'> in <interface type='bridge'> of domain xml? The detail <interface> in domain xml as below: <interface type='bridge'> <mac address='52:54:00:56:44:32'/> <source

Hi All, I have two kvm guests running with a bridged configuration bound separately to br0 and br1 on my Fedora 15 host. I'm attempting to create some nwfilter rules on br1 and am running into a bunch of problems that have me scratching my head. libvirt version: 0.8.8-7 What I've noticed on the second host is as follows: - Most all nwfilter rules that I create for the host on br1

I would stop the VM, edit its definition file (that's an XML file) and then start it up. But be careful: After you edit the XML file, you need to execute a command so KVM re-reads that file. I forgot that command, but you can look it up on Google. On Dec 9, 2015 7:52 AM, "Howard Leadmon" <howard at leadmon.net> wrote: > > > Maybe my google-fu is failing me, but I have

Hi Sam, You can find the rules by below command, and it looks as below: # ebtables -t nat --list Bridge table: nat Bridge chain: PREROUTING, entries: 2, policy: ACCEPT -j PREROUTING_direct -i vnet0 -j libvirt-I-vnet0 Bridge chain: OUTPUT, entries: 1, policy: ACCEPT -j OUTPUT_direct Bridge chain: POSTROUTING, entries: 2, policy: ACCEPT -j POSTROUTING_direct -o vnet0 -j libvirt-O-vnet0 Bridge
