...cial voice vlan. A config somewhat like this will do that for you. Make sure the * server has access to the vlan. This can be done by configuring an access port into the voice vlan, or to enable 802.1q on the * server. Anyway, this config will detect (with CDP) that a phone is connected, and the switchport will go into trunk mode, allow 2 vlan's (802.1q) to pass through it. If no phone is detected (or at least no CDP capable device) the switch will automatically make it an access port, allowing only access to the native vlan, so, the switch port can be used very dynamically. Of course you need...

hi, I have to configure Xen server and DomU''s which should be able to talk to different vlans - depending on services put on DomU''s. I would like to enslave 2 NICs via bond interface. Both NICs are on trunk ports which are configured in the same way, the same native vlan. I don''t know, if I have to add vlans tagging to eth* interfaces then enslave tagged eth*

Hello to all I would like to know If some of you have already configured an Cisco IP Phone (7940 or 7960) to work in a different VLAN than the PC that is connected through the phone switch? I know that this can be done with the Skinny firmware, but I dont if it works with the SIP firmware. The Cisco technical staff told me that these phones dont support 802.1x but can work as pass-through.

Hello all, I'm having unusual difficulty configuring teaming with Centos 4.2. The 2 NIC's are Broadcom. The HW is HP DL360 and there is no teaming driver for RHEL4 since it comes with package (says HP). Since there is no teaming driver from centos (as far as I know), I tried the Broadcom Driver, configured the team file, but the team just wont come up. A Virtual Interface should be up

I have recently upgraded my firmware from v6.3 to v7.4. Now when the phone is booted or rebooted, the initial screen "Initializing Vlan" takes forever to initialize before it initializes IP. Any ideas/Thoughts? (Trying not to Revert back to v6.3). -C -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hello all, I have a CentOS box that has a NIC (eth0) on which I defined 4 VLAN's (counting the NIC itself): eth0, eth0.1, eth0.2 and eht0.3. Initially the Cisco switch was not partitioned into VLAN's which means that the only VLAN running on it was the default one (VLAN 1). I have then played with VLAN's a bit on the switch and at this point have two: VLAN 1 (which is default and can

Hi, I have a Centos7 host with libvirt, attempting to boot a Centos7 guest. I am attempting to do the install over ipv6 (because why not). I have the following network configuration. Cisco 3550 gi0/1 <-> eno1 (Centos7) host. gi0/1 is configured as: switchport trunk encapsulation dot1q switchport trunk allowed vlan 1-17 switchport mode trunk Mainly in question is vlan11 as this is the network I am trying to work with. The switch have vlan11 configured with STP: # sh spa v 11 VLAN0011 Spanning tree enabled protocol rstp Root ID Priority 12...

...verything ok. However: when I started xend, the server instantly stopped responding. My Hosters Support said, that was due to a sort of mac spoofing protection in the switch, which disabled the Port, to which my server is connected, because there arrived an unknown Mac Address from my Server at the switchport. ( btw: at that point, I had not configured any domU''s ) >From the Xen Docs I understand that the bridge gets the mac from eth0 which is then diabled. So - I dont understand where the ''spoofed'' Mac is coming from. I''m thinking if it would be a solution, d...

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 with vlan 100 attached to a DOMU working fine. However, when I want to use native VLAN, I just can''t put switchport eth0 in a bridge and do the same setup as listed before. This results in br1...

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)

Hello, I''m used to using Xen in a bridge mode where my dom0 and all domUs are on the same layer 2 network. However now I have to set up a server whose eth0 is on one network and the domUs will be on another /29. So, for example, if the eth0 of dom0 is 192.168.1.214/24, then I have 10.1.1.0/29 (10.1.1.0 -> 10.1.1.7) routed to it for use in domUs, how would I go about setting that up?

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 explain why the moment you configure an IP from that VLAN on eth0...

Hi, We have 18 Windows Server in the same environment. All Windows Server are build with an individual Windows Image, we created before, which means, that all Windows Machines have the same configuration except ip/mac address and hostname. 17 of those Windows Server run Puppet within 120 seconds per run. But one of those Server took 49 hours for the run...the second one wasn''t

i have a customer that needs to plug the phones into the pc's using the pass-through rj45 available on most sip phones the question they are asking me is how to keep the data network separate from / secure from the voip network i understand they can set up vlans but i am hazy on a few details 1 since the phones are plugged into the pc's how will the phones be segmented into their own
