• ESXi 5, link group, VLAN and the Management Interface

  Greetings-

  I suspect that the answer to my question is: 'Buy an another NIC Intel' but here goes:

  I have a server ESXi here with 2 Intel GigE NIC, connected to the same switch managed ahead of Cisco.  A (vmnic0) NETWORK card is connected to the VLAN 200 while the second (vmnic1) is connected to the VLAN 300.  Ports on the Cisco are defined to access mode.

  Internally, the server ESXi, vmnic0 is connected to the 'public' vSwitch, while vmnic1 is connected to the "private" vSwitch

  I also updated the ESXi management IP 24 even as private vSwitch.  This is the key, I suspect.

  I tried to combine the two GigE interfaces in a connection unique 2xGigE and trunk two VLAN 200 and 300 through it.  After struggling through the menus on the ESXi console INTERFACE, I managed to get the IP management save and who responded and was able to connect to the server with the vSphere client.  I did it in X'ing the vmnic0 and vmnic1 in the configuration interface, then setting VLAN 300 in the configuration of VLANS.  But I could not the team/bundle correctly in the two vSwitches vmnic interfaces.  I could never attach a vmnic to one of the switches.

  Can I do all this with only 2 GigE interfaces and maintain access to IP management?

  SWITCH CISCO < == trunk w / VLAN 200 300 2xGigE == > SERVER ESXI

  VLAN 200 is a 28 audience

  VLAN 300 is a private 24 (for example: 192.168.100.0/24)

  IP management is 192.168.100.2

  I need to create a third VLAN for the management IP address and move?  If I master, say, VLAN 400 down to the ESXi server, use another block 192.168 for his IP address, I'll be able to take the vmnic0 and vmnic1 and team on the TWO vSwitches?

  Always follow me? ... :-)  If I can clarify this, by all means ask.  I apologize for the sort of random babbling here.  Thank you!

  Thanks for the pointers; I finally had the opportunity to try this out and it works as expected.  I EF you the 'right answer' but apparently the forum won't let me since you already have an answer of "useful".

  Nice that you got it working! When you perform the actual configuration with vSwitch Hash IP and physical switch LAG config, it might be a little difficult to do things in the correct order to not lose connection to the ESXi host.

• N2048 - VoIP QoS, data Ports and trunk Configurations

  Hi all

  I am new here and also new to work with the Dell Networking hardware. I just need to some insights into setting up a new network, that I put. We use 3 switches to N2048 for access to data and VoIP. Each port will have only have only a phone or a client PC in different VLANS.

  My question is what is the best configuration across all three powered to ensure that we have the optimum configuration for the quality of service for VoIP phones. Here is the configuration that I came up with this day.

  Global configuration

  VLAN, VoIP

  Voice port

  item in gi1/0/1 interface
  switchport mode access
  switchport access vlan 5
  VLAN 5 voices
  Voice vlan dot1p 5
  output

  Client port PC

  access mode swithport
  swithport access vlan 10

  Trunk Port

  Te1/0/1 interface
  switchport mode general
  VLAN allowed switchport General add 5,10,100
  switchport General pvid 100
  VLAN 5 voices
  output

  Thanks for the comments

  By default, the ports are configured to trust the priority of incoming user. So for your switch connections you can configure ports and trunk mode, there is no need to set general mode with VLANs voice, etc.

  switchport mode trunk

  switchport trunk allowed vlan add 5, 10, 100

  switchport trunk vlan 100 native

  For ease of deployment, I suggest to all the other general mode ports.

  switchport mode general

  VLAN allowed switchport General add 5,10

  pvid switchport General 10

  VLAN 5 voices

  With the general mode configuration, you can connect a client or a phone, or both at the same time, in a port. This will make things easy if later you decide to plug a phone in where a customer to reside.

• How to add a VLAN to trunk on Cisco SF200-24 port

  Hi all

  I have question want to ask:

  I have Cisco switch SF200-24, I want to Setup VLAN as below:

  1 to 10 of Harbour = Vlan 100

  11 to 21 Harbour = Vlan 200

  22-24 Harbour = Vlan 300

  Port GE1 = Trunking (primary)

  Port GE2 = Trunking (secondary)

  How to add all the VLAN 100, 200, 300 go through primary and secondary circuits?

  What port should I connect to management switch?

  Thank you

  > How to add every VLAN 100, 200, 300 go through primary and secondary circuits?

  first set the ports as trunks via the "VLAN management'-> 'Settings of the Interface' - click on the corresponding port, click on the button"Edit"and select"Trunk"in the list.

  Once these (GE1 and GE2) ports as trunks, you can now assign all the VLANS you want through "Management of VLAN"-> "a Port VLAN membership." Select the first port (GE1), click on "join the VLAN" and select VLAN all desired from the list on the left and put them in the list on the right.

  and you're done.

  > Which port I can connect to management switch?

  the default management IP switch is part of the default VLAN1. If you want to keep access to the switch, assign "VLAN1" to one of the ports of access, or change management VLAN number other than 1 - but in this case remember to apply the correct IP settings in order to satisfy the subnet assigned to the new VIRTUAL LAN.

• 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.

• Mapping VLAN and probe Inline

  Hello

  I'm doing all my traffic flow of SSL VPN clients through a traffic Inline probe. From what I see, I should use the mapping feature VLAN. But I can't understand how the function works. ASA not very informative or extensive documentation.

  Currently my ASA has a network of interconnection on a VLAN to my router base, and all my internal network is routed to the base IP address. Default gateway of the router of my Core is the ASA. My ASA provides IP addresses to remote VPN SSL clients and is the default router for them. Remote traffic follows the remote client to the ASA, then through the interconnection to my internal networks. My only ASA works as my perimeter firewall and SSL VPN concentrator.

  I have map VLAN undestand will make all traffic from the remote clients to abandon the vehicle on a VLAN individual. So, I created a new VLAN and that added to a trunk on the SAA. Then I activated "restrict access to VLAN" and set it to my VIRTUAL LAN. My traffic Inline probe is connected to the VLAN and can provide DHCP.

  If it were a classic network, I'd Inline traffic probe the gateway by default for this VLAN and provide IP addresses and gateway with its DHCP server. But how does it work with ASA? I can in captivity the evacuation to this VLAN, but cannot find a way to make the traffic passes through the screen. As ASA does not support routing based on the source can't make the jump next to the probe traffic.

  I can do the bridge of the probe (L2) network for interconnection and the remote client VLAN. But the IP address of the ASA on the VLAN does not fall within the same range as the interconnection, so I can't understand if and how it worked.

  Can someone help me with the configuration or explaing me better how works the mapping VLAN?

  Thank you.

  What you are trying to reach is configurable through the "tunnel" default route, and it would force all traffic of VPN with this default route special.

  for example:

  If your traffic probe Inline between the ASA inside your heart and the interface, you can configure:

  Route inside 0.0.0.0 0.0.0.0 in tunnel

  Requiring all VPN traffic route to IP CORE that would go through your online traffic probe

  Here's the order for your info reference:

• 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

  Mark J.

  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.

• 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.

• 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,

  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

• 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.

• 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.

  Hey, Sunil,.

  With regard to your questions:

  1. we have a case of Dot1Q configured on the port of access of habit?  If not, then why? - Dot1q aims to tag executives leaving the switch and access is opposite, it does not therefore not used together marking.

• several subnets by VLANS and ports link

  Hello

  I need some clarification.

  Our iSCSI SAN storage (Dell MD3660i0 requires a separate subnet by port.

  We require paths multiple access and balancing in VMware.

  To achieve this in ESXi 5.1 we need binding ports... BUT the binding of ports is supported only if the vmks are all in the SAME domain in accordance with these two KBs broadcasting

  VMware KB: Considerations for use binding software iSCSI ports in ESX/ESXi

  VMware KB: When the use of several VMkernel ports with port required to access the storage of two or more tables on different br...

  OK... probably so I simply put my all subnets in ISCSI storage in one VLAN and everything will be ok (one VLAN is after all a broadcast domain, both are stuff of L2)... This would respond to the requirements of KBs... If VMware means "area of distribution" in the true sense of the term.

  So my question is can you configure the port in this way binding? It is supported by VMware?

  VMware has come back to me (in fact the author of one of the kb/s I've referenced)

  http://KB.VMware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalID=2038869

  He confirmed that the terminology used in the KB is misleading and "broadcast domain", it actually means "subnet" so not layer 3 layer 2.

  This means that you can NOT have multiple subnets in a broadcast domain (VLAN) AND use the SW iSCSI port binding.

  BUT

  He told me (he is very familiar with the Dell MD3660i iSCSI kit), you don't have to have binding of ports to achieve several Multipathing and load balancing. If you have a requirement for several subnets of your iSCSI SAN provider then just create multiple vmks on different subnets, and DO NOT make the port binding. The fact that they are on different subnets will be enough to achieve the multiple paths

  It updates the KB to make this much clearer.

  I hope this helps someone
