Hi All, I posted this question several days before, as if no one reply, any help, hint would be highly appreciated! PLEASE SAVE ME! Now I am having trouble in Ethernet bridge and 802.1Q VLAN, I have the following network: Internet | | Gateway | | <--------- If insert one Ethernet bridge box in here ,somethings changes | H u b ( one normal

Hi All, Very sorry for posting my question again, because I want to tell you more details on my issue, and it is very important for us! Now I am having trouble in Ethernet bridge and 802.1Q VLAN, I have the following network: Internet | Gateway ( One UPNP device) | | <--------- If insert one Ethernet bridge box in here , somethings changes | H u b

Hi All, For my issue, first thanks to ALL, I have some idea of it. Also Thank Peter for his kind remind, I would become one good guy in this list. Most mentioned MTU, but how I assure that the problem is just MTU, how I debug it? Here is my bridge configuration: Internet | | Gateway | | eth0 Ethernet Bridge | eth1 | H u b ( one normal hub

Hi All, I am having trouble in Ethernet bridge and 802.1Q VLAN, I have the following network: Internet | | Gateway ( UPNP device) | | H u b ( one normal hub or switch , no VLAN) | \ | \ | \ Some 802.1Q VLAN Switches ( their uplink port is tagged) Our PCs connect with these VLAN Switches, they access Internet through the

Hi all, I am testing one QOS system, I want to control bandwidth by VLAN id. Here is my test network: Internet Gateway | | QOS control box ( Bridge box, Redhat 9, 2.4.28 kernel with ebtables-brnf-8_vs_2.4.28 patch) | | VLAN Switch | | PC PC In my QOS control box, it is a bridge box, I used Redhat 9, 2.4.28 kernel with ebtables-brnf-8_vs_2.4.28

I'm trying to bridge a mix of 802.1q tagged and untagged Ethernet frames through the new Ethernet over GRE functionality in kernel 2.6.28 The hosts handling the tunnel (192.168.200.6, 192.168.200.2) are connected together through with a simple cross cable through their eth1 interface. The switches are connected to their respective eth0 interface, which is bridged with their respective gretap

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.

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

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

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 can

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

And additionally here are the detailed port configs on the switch end: hq>show interface Gi1/0/3 switchport Name: Gi1/0/3 Switchport: Enabled Administrative Mode: trunk Operational Mode: trunk Administrative Trunking Encapsulation: dot1q Operational Trunking Encapsulation: dot1q Negotiation of Trunking: On Access Mode VLAN: 48 (VLAN0048) Trunking Native Mode VLAN: 48 (VLAN0048) Administrative

Keir, This patch fixes cirrus and rt8139 co-exist issue in new qemu-dm. The root cause is that if two MMIO spaces are continuous, qemu may misuse last MMIO space''s read/write to handle current request.

Hello, My name is Ferm?n Gal?n and I work as Research Engineer at CTTC, Spain. I'm trying to configure a bridge with brctl to switch VLAN tagged traffic (802.1q), but I'm getting some problems. In particular, I've a physical interface (eth2) connected to a Cisco trunk port (so, the traffic to/from eth2 is tagged). I've added eth2 to a bridge ('brctl addif somebrige

OK, thanks again for all your help. I have resolved this, finally. The problem was that I configured VLAN 48 as the native VLAN on the trunk port.That was a mistake as apparently the native VLAN is the one where Cisco does not bother to tag packets. For now I set the native VLAN to VLAN 1 and that works. Cheers, Boris. On Sun, Jan 25, 2015 at 7:13 PM, Boris Epstein <borepstein at

Hi, I have created a libvirt network on top of a OVS bridge (named vlan-br) which receives all VLAN tagged packets, i.e. connected to a trunk port. The definition xml is below. What I want to achieve in the portgroup definition 'trunk-native-1221' is to allow 1221 as untagged/native but rest all VLAN as tagged. The following portgroup definition works, but I don't want to enumerate

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: hq#show arp Protocol Address Age (min)
