• LAG, VLANS and Trunking Force10

  I'm with vSphere and I a vSwitch with several groups of ports configured, including 2 assigned to VLAN ID and a network of management with no Vlan ID.  This vSwitch will use physical NIC grouped to route this traffic to a physical Dell Force10 MXL switch.  My understanding of the standard networking, a trunk port must be configured and VLAN must be added to this as labeled trunk port, while the traffic that has no Vlan ID is left unidentified and by default is the vlan by default (usually Vlan 1).  The attached picture is the topology I and I need to make this work, but do not have a lot of experience with Force10 switches and so far, it looks very different.  In addition, if it is relevant, the external switch in the diagram is actually 2 Force10 switches separated stacked, and there are two connections to the other switch (currently a 6224 not managed) between the firewall and F10s, which is a separate issue - those must be configured as an OFFSET on the F10s and the 6224? One or the other?  Or?  If anyone can help with the configuration for this topology?  Please help me out here.  Thank you!

• Question about traffic portgroup and vswitch

  It is my understanding that the network traffic between virtual machines on the various exchanges on the same vSwitch will stay within the vmkernel and not go on the wire to the physical switch. This makes sense because it is the most effective way.

  Is there a way to force traffic between exchanges on the same vSwitch back on the bear to the physical switch?

  If you wonder why, we try to avoid having to use the method of marking of external switch (EAST) to deal with the VLAN and ESX.

  Using the virtual switch, but will achieve what you want, give the PGs a VLAN tag and the external switch in trunk mode configuration. There is a good PDF VMware explaining how to configure.

• Tagged management VLAN and the virtual machines on the same VLAN

  I'm faced with a problem related to our Brocade switches newly acquired and get the private VLAN to work on trunk connections to our ESX servers.  Every time I try something different, he creates a new problem.

  In our configuration, our management of VLAN is not tag and we have a VLAN for this management network that is placed on our switches VLAN no marked native.  We also have virtual machines hosted on those same ESX servers that are on the same VLAN and everything works fine.  However, when I change the ESX management to carry a label on this VLAN and change the switchports accordingly (IE no untagged VLAN native), management work, but hosted on the ESX Server machines that are on the same VLAN can get no network connectivity.

  Is it possible to have a management network labeled and also the host of virtual machines on the same VLAN or is it totally impossible?  I'm not very familiar with networking behind ESX, so I apologize if this is a dumb question with an obvious answer.

  Thank you

  Is it possible to have a management network labeled and also the host of virtual machines on the same VLAN or is it totally impossible?

  Yes, it is possible... why it doesn't work for you I don't know, but try the following:

  1. set up the Group of ports of VMS to use VLAN;

  2 configure the interface of management VMkernel port group use VLAN;

  3 configure the physical switch port to allow to this VLAN and put the default VLAN natively for these interfaces.

• VLANS and virtual switch

  Looking for advice.

  Currently, I have our Vmware 4.0 servers configured with 4 NICs.   vSwitch0 (2 network cards) and vSwitch 1 (2 network cards). Switch 0 to several groups of ports for each vlan I have (on 8 VLAN) switch 1 a the VmKernel for NFS.  It works very well, I have a new server on order and I thought that I have would consider this configuration to make sure that I am maximimzing my performance.

  I get a little confused, it seems that I could create multiple vSwitch with the same NIC 2 and have a group of ports under each of them for the Vlan vs 1 vSwitch and several groups of ports.  If this is incorrect, please correct me.

  Benefits or drawbacks to this?

  If you had 4 network cards and several VLANs using NFS for storage, which would be the best config for performance and failover?

  What happens if I had 6 network interface cards (new server comes up with 6)?

  Thank you

• VLAN and ESXi 3.5 U3

  At home, I have a DL380 G4 with ESXi on it

  what I want to do is to create a trunk dot1Q to a cisco 2960

  I want to do 6 7 maybe Vswitches with a tag of vlan diferant

  IE (Vswitch 1 to vlan 1 and put only the management of the interface on this vswitch)

  then create VM I want is maybe on other VLANs (for example if I want to have a virtual machine directly on the internet, I would be able to use vlan 7 and not worry that someone could hack into the host or any other virtual machine)

  can do this and how?

  also I want to the team or etherchannel 2 network cards

  If you create switches 6, or 7, you would need 6 or 7 physical network adapters, because you can't share a physical nic between vSwitches. I suggest to create 1 vSwitch with multiple exchanges, you would be able to define a vlan to each portgroup. If you add two network cards in the vswitch containing exchanges you also redundancy!

• LRT214 VLAN and site to site vpn

  Hello everyone, I am a bit new to the network of this aspect and was looking for some advice.  I am looking for several routers LRT214 to configure VPN site to site to our main office at 4 locations.  There are 2 VLANS and subnets - one for the network secure (vlan native 1) and one for comments wireless (vlan 2).  It is very good and works well for lan segregation locally.

  IPSEC tunnels do not pass the tags vlan, my question because I will be able to restrict traffic through the vpn tunnel to vlan 1 and deny traffic to vlan 2?

  It appears in the documentation that VPN traffic can be limited by IP address or the local subnet.  My concern is that if there is no way to bind or bridge to the VLAN selected, an adjustable static IP address on a device on the vlan 2 were part of the traffic permitted (vlan 1 range), and therefore cross the tunnel for devices vlan 1 on remote sites.

  Thanks for any input you can offer.

  Hi, seedtech. The VLAN used for the VPN is the default VLAN. So if a tunnel is created, it will cross through the default VLAN.

• Help with the VLAN and RVS4000

  I am trying to Setup VLAN on a RVS4000 to share our Internet connection with another office but do not allow access to our network of the other network. We have a BEFSX41 connected to Internet and also connected to our other site via a virtual private network to another BEFSX41. Port 1 on the BEFSX41 connects to Port 1 on an EZXS88W switch.

  The other company has provided the RVS4000 and also provides a WRT54GS router. I want to connect 2 ports on the BEFSX41 to Port 1 on the RVS4000 and 2 ports on the RVS4000 to track 1 on the WRT54GS.

  Port 1 on the RVS4000 is member of the default VLAN1 and Port 2 will be a member of VLAN2.

  Our IP network is 192.168.20.0/24

  BEFSX41 is 192.168.20.1

  The DHCP service is disabled

  The RVS4000 has a static IP address of 192.168.20.254 and is configured as a router

  DHCP is also disabled

  The wireless network is as follows:

  IP network is 192.168.21.0/24

  The address IP of WRT54GS is 192.168.21.254 and is static and also configured as a router.

  I don't know how to actually Setup the VLAN from here and the instructions are not useful. My questions are:

  1 port 1 on the RVS4000 must be safe, with label or Untagged?

  2 If the interval routing disabled?

  3. If so, how do I route between the RVS4000 and WRIGHT so the two networks have access to the Internet, but not to other networks?

  The befsx41 should be one that is connected to the internet so that your final point so that the vpn tunnel work. The wan port on the wrt54g must be connected to the lan of the befsx41 port.

  If your server is located behind the befsx41, you should be able to port forwarding. If your server is located behind the wrt54g you may experience the problem with the redirect because you need to forward ports on both routers and according to me, there are some applications that do not work on double NAT.

  If you want to have access to the internet on both VLAN of the rvs4000, it should work as a router so its internet port must be connected to the port the befsx41 lan.

• Example config for 2 management vlan and ip Routing.

  We have a stack 6224, we use two vlan on it

  VLAN network 10.1.1.X 24 10

  VLAN network 192.168.0.X 24 40

  Our workstations reside also in the 10.1.1.X network, so we need to administer the switch there.

  192.168.0.X traffic must be routed to 192.168.0.X (and vice versa)

  How can I set this up, when I set up a 10.1.1.1 address for the administration interface and vlan 10 I can't configure the routing for this vlan?.

  (Actually I don't want to just out-of-band of our lan fault management)

  Please advice,

• Implementation of VLAN and QoS for VOIP on SG200-18

  We recently purchased the smart switch SG200-18 to replace a Netgear switch. We are moving our phone service to VOIP through our local ISP as well.

  I currently have the VOIP phone plugged into Port 17 on SG200-18 (it is a Grandstream Cordless VOIP phone).

  I want to put the VOIP phone on one VLAN separate from the rest of the network and optimize QoS parameters so that the VOIP phone has exceptional audio quality even during network traffic.

  Here are my questions:

  1. do I need to set anything on the type of port to Port 17 (because it resembles a shape any Combo port)?

  2. How can I do to isolate VOIP telephone it's own VLAN (I see the parameters VLANS and VLAN voice, not sure that one to use;) I've tried to set a VLAN and broke the Internet connectivity on the phone until I went and removed)?

  3. do I need to adjust the QoS settings to switch to better optimize the VOIP phone?

  Some additional questions about the GS200-18 in general:

  1. do I need to adjust the parameters of the system on the switch time? I am in the Central time.

  2. do I need to adjust the Green Ethernet/Energy Saving parameters or should I stay with the default settings?

  In addition, a couple of "getting started" questions for Cisco:

  1. I registered an account My Cisco. What should I do to register my switch with Cisco and associate with my My Cisco account?

  2. What are the benefits of purchasing a contract of Cisco Small Business support, and how much would it cost the SG200-18 (I ordered it from Provantage)? I'm curious to see if it's worth the money.

  Here's my 'features ':

  Switch: SG200-18

  VOIP phone: Grandstream DP715 and 710 handsets

  Plugged in: Port 17 on SG200-18

  Services: Internet Local (Direclynx)

  Type of connection: 3 m down / 500 k up DSL move to a future wireless connection that will give us higher speeds

  Backend VOIP provider: VOIP Innovations

  Router: Apple Airport Extreme AC model (all Macs and iOS devices and the OS X Server on the network, so I use the Apple router facilitates installation, because is not QoS, trying to QoS and VLAN in the switch)

  Thank you all!

  Hello

  I'll just go to the list again:

  1. sounds good in the port from the drop-down list. So can I just connect the VOIP phone and go with it, correct?

  Yes, just plug in ethernet combo port and it will work.

  2. is not an issue, but I agree, Apple likely isn't compatible QoS or VLAN.

  3. thanks for the info on time/NTP settings. If I wanted to go there and try to configure NTP, how much is it and what I have to do? I want to I can give it a quick try.

  To Setup NTP on the switch is quite simple.  Go to Administration > Time Settings > time system and check the boxes to activate the main clock Source (SNTP)

  Then go to the settings of the SNTP page and add a new entry with the IP address of an NTP server.  There is a list of available NTP servers here:

  http://www.pool.ntp.org/en/

  You must also ensure that the switches Administrative default gateway is set correctly (it must be set the to the default gateway, probably the most convenient airport) so the switch can contact the NTP server.  That option is set under Administration > Interface Management > Interface IPv4.  Change the user-defined default gateway and enter the IP address of your airport (or whatever your default gateway for your network)

  4 sounds good on the Green Ethernet settings. I'll leave it as default value.

  Yes, better to just let those unless you have weird problems with ports disconnect, who can sometimes be caused by Green Ethernet, but if there's nothing like leave it on and save a few watts.

  5 sounds good on does not need to attach my passage to my Cisco account. Should I fill out a form any registration of the product with Cisco before calling support?

  It is not a record for support.  The only thing we need you to do is to create a Cisco account, but you have already done this, so if/when you call in support, you just need your ID for Cisco (also called a CCOID sometimes) and the serial number of your switch.

  6. thanks for the info on the Service contract. Is it something that I would need to order directly from Cisco or I who would get my Cisco partner (Provantage)? After the three years is up, treat yourself to renewal or it just falls? Is there a certain amount of time I have to buy the Service Contract forward make me ineligible?

  Support contracts are purchased through a partner Cisco, or you can get them online for the CDW or Newegg for example.  Basically, you have until the expiry of your current aid for the purchase of a new contract.  For example, right now your switch comes with 1 year of technical support.  You can only buy a contract while it is still active.  Once your three-year contract is about to run out, you're in the same situation.  You can renew it before it expires, however if you leave is up, you will not be able to put a contract on it.  Contracts are not my specialty, however, so you can check with your partner for complete details.

  7. sounds good to how data use VOIP calls. His dislikes too. :-)

  I agree, a voice call is not much traffic.  What you have described you probably don't have problems, although of course I can't guarantee that.

  8. because it is from your provider and they specifically mentioned the VOIP, I would say that you'll be fine here.

  You had also placed on your airport using access point behind a router in small businesses.  I would like to say that it is possible, a large number of wireless routers have an option to put access point only mode or something like that, but you should check with Apple on how to do it.

  Insofar as a Small Business router if you decide to upgrade for the options VLAN or QoS, I would recommend the RV180, or perhaps the RV320.  Two of these models are available with or without wire depending on what you decide to do with the airport.

  I think I got all the questions, but if not just let me know,

• Wirless VLAN and DHCP

  I am trying to configure my Aironet 1121 G acess points with several VLANs, got the VLAN everything works great with wired devices, but wireless devices don't you DHCP.

  Basically I have the BVI on my virtual LAN management and two other vlans that cross, try to have the public WiFi on 1 vlan and the two VLAN corporate with separate wifi. Impossible to get IPs on any of them though.

  Vlnas are moved by a catlayst 3550 with addresses of assistance set up on all the VLAN interfaces.

  DHCP comes from 2 boxes of windows on another virtual local network Server 2003

  any ideas?

  Hello

  If I understand, you have plugged your access point to one of the L2 switch. I suggest you to set up your L3 (tandem switch) with pool dhcp to obtain the ip address for vlan respective first.

  To set the dhcp pool in your L3 192.168.2.1.

  create interface IVR and IP address assignment for the VLAN respective (which will act as a gateway of the vlan respective)

  Repeat the same for all the VLANS.

  Create the DHCP pool for the vlan respective and router by default with the ip address of L3.

  AccessPoint#configure terminal
  
      AccessPoint(config)#interface dot11radio 0
  
      AccessPoint(config-if)#ssid .......give the name of your ssid
  
      AccessPoint(config-if-ssid)#vlan ?

  Check if you have the ip address for the customers.

  In case await you get the IP address of your external dhcp server...

• SGE2010 switches, VLAN and a port blocked by spanning tree

  People,

  I have 2 groups of switch.

  SGE2010 2 with VLANS is defined as 10,20 and 30

  VLAN 10 is the management VLAN and it uplinks to our border router.

  VLAN 20 is the workstation VLAN, and all workstations are pointing to the switch as their default GW

  VLAN 30 is the ip phone VLANS, and all phones use this as a gateway.

  I have a GAP between the switches said, we have a few servers on the ip phone switch that must be accessed by the clients of the workstation and the unique link of 100 MB through the router probably won't be enough.

  If I understand correctly, because the switches have different networks on them, a simple shift will not work. I did create a gap and addresses on each side, but it does not appear in this mode, I can block vlan 10 transit to the LAG, with this block I'll end with a logic loop and spanning tree will block the uplinks or LAG itself.

  I have attached a picture with a diagram of our current put in place.

  Any help/advice would be much appreciated.

  John, the 802 standard. 1 initial q indicates there isn't only global tree covering weight independently of belonging to a vlan. It's why you run into problems. Cisco has developed PVST to run on circuits of the ISL. BPMH was originally defined as 802. 1s, which is a combination of 802. 1 q + RSTP. The 802. 1s were later modified to become part of the 802. 1 q.

  The person is incorrect, because they cite "because spanning tree is construction by vlan. They are incorrect, because you have to set the properties of tree cover to allow the spanning tree protocols by vlan. Small business switches do not support the owner Cisco PVST and PVST +. However, the SB switches support BPMH which is a standard of the IEEE.

  How works the BPMH, it's that you have called proceeding, i.e. each construction covering tree. Then you have the region, SB switches support only 1 region. The region maintains the instances. Basically how it works, you activate the EMU at the global level. Then, you specify the instance. As an example, the vlan 1 is instance 1. VLAN 2 is 2.  This will allow you to run 2 physical wires between switches vlan different without looping. If you use classic STP or RSTP, the least costly path will go to the State to block/cast who works as expected.

• Several VLANS and DHCP relay on two stacked switch SGE2000-G5

  We were put to the task of securing a small desktop system managed that is currently set up with a standard switch for each of the offices (with different companies) to see each other and in some cases, access to each of the other documents on the network.

  Obviously, this is far from adequate set up and our goal is to isolate each office using VIRTUAL networks, but share a common internet connection provided by managed offices.  We have two switches for layer 3 Cisco SGE2000-G5, but we are new on Cisco equipment and VLAN, so we are not quite sure on how to implement this.  DHCP must be provided by a router, there is no server.  We are open to suggestions on the router as we still buy a.

  I hope that someone may be useful.

  Thank you very much

  Jim

  Hi Jim,.

  SGE2000 switches you are using must be able to handle this without issue. What type of router you are using? As long as you have a router that will take in charge VLAN / several subnets, it should be a simple configuration.

  Here's a quick run down of the measures to be implemented. (using vlan1 and vlan2)

  On the router, create a vlan / subnet 2 and set the port to connect to your shared resources with the two VLAN 1 and 2 switch. (it will be untagged, two will be marked)

  On the switch, create vlan2 and do the same for the port connected to the router. (vlan1 marked and tagged vlan2)

  Now for each switch port that you want to assign the port access and vlan1 and vlan2. (this vlan will be without a label)

  If your router allows, disable routing inter - vlan. If this isn't the case, you must create rules to block traffic from one network to the other.

  All this happens under the assumption that your router can support VLAN and can also make DHCP for this VLAN.

  Hope this information helps

• VLAN and the SSID does not not in the Web Interface

  We have a couple of APs which do not show the VLAN and via the web interface of AP SSID.  If you go to the SSID Manager page in the web interface, the page rises but doesn't show any SSID configured.  It goes the same for Services - Vlan.  This page appears but does not show in any VLANS configured.  If you telnet to the APs, you see the mssid listed and all the SSID interfaces.  The SSID on the access point is functional and working.  It is just so hard to use the web interface for these APs.  I tried to compare configs running on APs where the web interface does not show this and APs that it shows, but cannot see any differences.

  Thank you.

• Create a vlan and conf coelio

  Hello

  I need create 2 VLAN (vlan 10 and vlan 30) to the Cisco 300 series switch.

  VLAN 10 must be default VLAN (no tag).

  After that I wish to associate VLAN10 1 and 2 to 30 port of VLAN. The two ports must be access.

  If anyone can give a step by step to do this?

  Best regards.

  Hi Andre,

  Make a fiour minute video to show you how create two VLANS and I think answering your question.

  After making the changes, I suggested, be sure to save the configuration to the switch.

  (the audio is dead as I began to save the running configuration to the startup configuration)

  In addition, it is not stated clearly, but in the page of "port of VLAN" make sure that you select go after selecting a VLAN to change. See the go button circled in the screenshot below.
