Hi to the ML. I''m new to VLAN configuration, and combining it to XEN is a bit difficult. I want to use VLAN because it''s possible to "arping" from a domU to an other, and VLAN looks like; the only solution to prevent that. May be I''m wrong if someone got a solution, I may be interrested. I''ve also tryed ebtables, but nothing to prevent arp

Hi, I would like to know if somebody can point me out how to configure several DomUs in a private LAN (for example 192.168.100.0/24) and one DomU with two interfaces (one - 192.168.100.0/24 and two - internet). So far I have enabled in xend-config.sxp: (network-script network-route) (vif-script vif-route) My config files have: /mnt/VM/1.cfg:vif = [''ip=192.168.1.3'']

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

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

<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

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

Hello to everybody, Sorry if my english isn?t very good. I need pass 802.1q through a VPN between two offices. I have mounted a WRT54GL, with OpenWRT firmware, conected to a switch trunk port in both offices. In the switch of the first office I have created five tagged VLANs and I need pass these VLAN to the second offices where it has created it too. Can I do this with Tinc in HUB/Switch

--- 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

Hi, examining the network traffic with wireshark shows that asterisk does not set any QoS values at all. What do I need to do to make asterisk set QoS values (on Centos 7)? The wiki says to use vconfig to set QoS values[1]. What does the skb-priority need to be set to? How do you use vconfig on interfaces that are not VLAN interfaces? Is it generally impossible to set QoS values on

Hi, I am configuring some servers in a high availability setup. The servers are connected to two switches with two LAN cards in each server. The two switches are connected directly to each other. The servers are configured to bridge eth0 and eth1 with spanning tree. Usually this makes sure eth1 is disabled, unless something happens to eth0. This way I can have one IP address on each server. Now

Hi All, I''m using xen 3.0 on CentOS 5 with VLAN. #vconfig add eth0 100 #/etc/xen/script/network- bridge start vifnum=1 netdev=eth0 bridge=xenbr0.100 I know that after xen 3.2 the procedure of bridge configuration is changed. What is the correct command to set bridge interface to vlan? Yukio

Hi all, I''m having a hell of a time getting my IFB to work. I know I''ve done this before, so I''m missing something stupid. Can anybody tell me what it might be?

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 ... The

Hi Krishna, 1) If you want to classify according to MAC address, you could use iptables to mark the packet (using MARK target), but just source MAC is available for now. 2) Usually tc just could classify by fields of IP layer and its sublayer, so I think classify by ethertype is unavailable. 3) VLAN tag belongs to MAC layer! I''m not sure how to QoS for VLAN, can anybody give some

Hello I have few questions regarding tc functionality (qdiscs, classes, etc.) when vlans are in use. For example, consider interface eth0, for which I create and extra vlan with vconfig, let''s say eth0.11. Then using tc I can add usual things - qdiscs, filters, ... - to both eth0 and eth0.11. The questions are: - on which interface - virtual or real, should I actually use tc ? Or
