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

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

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.

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

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

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

Hi All, Today is a great day. My hotmail login error is fixed. Following Peter's advice, I used e1000 card, don't change any MTU , the hotmail login error went away! It is MTU issue, for VLAN tag traffice going through the bridge, the NICs in the bridge need support VLAN tag, e100/e1000 card can. Thanks to Peter, Stephen Hemminger, and All ! So far I know Intel e100/e1000 card can

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

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

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

Hi all, Is it possible to have native VLAN (802.1q) and a VLAN x at the same time in DOMU''s? This is what I have configured on my DOM0 (xen2): Eth0 (connected by a 801.1q trunk to Cisco 2950 switch) Created vlan100 : vconfig eth0 100 Created bridge : brctl addbr br100 Attach switchport: brctl addif br100 eth0.100 Attach a DOMU : brctl addif br100 vif2.0 I now have bridge br100

Just curious, if I have my Polycom IP 550 phone VLAN tag 30, will the packets I send from my PC(on the PC port of the phone) have the same VLAN tag? THe PC is sending untagged packets. This e-mail, facsimile, or letter and any files or attachments transmitted with it contains information that is confidential and privileged. This information is intended only for the use of the individual(s) and

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)

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

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
