• PowerConnect 5548 and VLAN

  Good afternoon!

  I'm looking to implement a 5548 in our existing infrastructure. I want to preface this by saying that I am very new to networking.

  I'm looking to have at least two VLANS separated.

  -The first vlan for public sites face. These will have static public IP addresses.

  -The second VLAN is iSCSI traffic. I would like that it won't face public.

  Is it possible to Setup or should I be looking for a different solution.

  If possible, how should I go about setting up?

  Thank you!

  The port that connects to your router should be placed in Trunk mode with the VLAN you want in the trunk port. All ports are in VLAN1 access mode by default, this means that the port that plugs into your routing device is in access mode for VLAN 1 and VLAN 1 has internet access. For traffic VLAN 2 to access routing equipment that you will need to change cela port in Trunk mode and adds 2 VLAN as a VLAN Tag.

• Subinterfaces and VLAN

  Hi all

  I was hired on with a State... Now its been awhile, but I do not remember how subinterfaces and VLAN all link together!

  Now correct me where I'm wrong (please), but them VLAN is created on the correct first switches?  When you create a VLAN on a switch you don't need ip or gateway address by default because them VLANS are the switch.  If you want intervlan routing you need a router.  Then, you configure a port trunking between the switch and router (ISL, 802. 1 q).  Now in the router, you can create a VLAN, and here you inter the ip subnet or the default gateway addresses correct?  This is where I get confused as to what reasons do you need subinterfaces?  How they roped VLAN and what would be the logical flow of data?

  Anyhelp would be appreciated!

  Yes you are right. If you are using the layer 2 switch and want to make the intervlan Routing then you need Layer 3 router device. But you must configure the interfaces sub with the default gateway to route traffic. Because there is a single trunk between swich and router so we need sup interfaces for multiple VLANs.

  Interface FastEthernet0/0.1

  Encapsulation dot1q 10 (10 represent 10 ID VLAN)

  10.1.1.1 IP address 255.255.255.0

  If you use a layer 3 switch, then you point all sub interfaces need so then you can create the interface vlan with the default gateway. You must enable ip Routing.

  Interface vlan 10

  10.1.1.1 IP address 255.255.255.0

  Hope this will help.

  Please rate if this can help.

• VPN and VLAN

  We have a site divided into 2 IEE802.1Q VLAN, using no switches Cisco. They have a PIX515 for Internet access. It is also configured to provide inbound VPN access for management and general purpose of access.

  In principle it is possible to set up a new VPN connection which is reflected by its interior traffic be tagged with a specific VLAN ID while all other traffic (including other VPN connections) remain without a label?

  If the PIX ends your VPN from the outside that the answer is no. If the VPN is coming from outside, and ending at the PIX she never travels a VLAN. VLAN tagging is used to identify what VLAN came from a source image and what VLAN it is intended for a current switch vlan can 'route' frame through the appropriate VIRTUAL LAN. Why you want to tag from outside VPN traffic? If it's to control access, you can specify 2 VLANS and VLAN 3 on the PIX (as long as it has code 6.3) and control what VLAN, you want that each group VPN access to through the use of the ACL. Each VLAN on a PIX is treated as a physical interface. It has its own security prefs (0-100) and can have ACL applied to them as well as the physical interfaces.

• Create 2 VLAN (VLAN 1 and VLAN 2)

  Hi all

  I need help and advice with my new Cisco SF300-48. I want to create 2 vlan (vlan 1 and vlan 2). The switch is set at layer 2.

  example:

  VLAN 1 (port 1, 2, 3), vlan 2 (port 4, 5, 6)

  VLAN 1 can communicate with each other (port 1, 2, 3) and vlan 2 can communicate with each other (port 4, 5, 6)

  But vlan 1 cannot communicate with vlan 2.

  Any help would be appreciated

  Thank you

  Johan

  Well, as far as I understand the message communication between the VLAN is not necessary. The thing is, that all ports LAN VIRTUAL (for example VLAN 1 with ports 1, 2, and 3) cannot communicate with each other. Did you check the configuration of the port / VLAN (VLAN configured to each port configuration right / right about the tag-no identified)?

• Management and Vlan native in different subnet?

  Can I have a management ip and vlan native in a different on AIR-1242 switch subnet and 2960?

  Native on switch = 1.

  The interface vlan 100 = 10.10.1.25X 24

  BVI ip to the vlan 100 = 10.10.1.25X 24

  -HM-

  Hello

  As far as I know, the management and the native will be the same... I guess... You have Vlan native as 1 on the switch and Int Vlan 100 on routing switch? Am I wrong? Let me know what are your needs... which will help me to help out you!

  for your question...

  Normally, we specify him vlan native on the switch and the AP so that communication happens... communication won't happen if there is a match of...

  Looking forward to hear from you!

  Let me know if that answers your question...

• With the help of VLANS and VLAN Tagging is not working / no connection

  Hello

  I m trying to configure a VLAN between some virtual machines on ESX host 3.

  I want to do this way:

  http://KB.VMware.com/selfservice/microsites/search.do?language=en_US & cmd = displayKC & externalId = 1004074

  I got 1 dedicated NETWORK adapter to each ESX host that is connected to a dvSwitch in which I configured a portgroup

  with VLAN ID 2121. I have configured each virtual machine to use this network.

  When I put the virtual machines on a single host, they are able to communicate.

  When they are placed on different hosts they are (if the VIRTUAL LAN is enabled on portgroup) not able to communicate.

  So I m assuming it must be a problem in the config NIC on the ESX host or switch.

  I m using a HP2910AL on which I activated mode trunk for each port that is connected to a NETWORK card with

  the dvSwitch/Portgroup I try to use for the vlan. In the hp switch, I have a default VLAN with ID 1 where

  the Ports are marked not signposted. I install a second VLAN on the switch with ID 2121 in which I scored

  This tag ports.

  Is there something else to do - perhaps side ESX host?

  I tried changing the settings as "forged transmission-> allow ' on portgroup and I found other things

  in the web, but always without success.

  Kind regards

  Patrick

  Were you referred to this guide? :

  http://CDN.ProCurve.com/training/manuals/2910-ATG-Feb09-2-VLAN.PDF

  "show vlan ports" would be my next check to make sure that you have connected to your ESXi host 3 ports in the vlan 2121.

  As Duncan has said if you have a VLAN ID on the portgroup in the vSwitch and you have the port on the pSwitch as trunk not acess and VLAN ID is allowed on the trunk port pSwitch you should be ok.  Just to clarify the trunk is 802. 1 q No 802.3ad.

  The reverse is not VLAN ID on the portgroup vSwitch, use coelio on pSwitch with VLAN ID.  Limited pSwitch port to a VLAN, this may be ok for you?

• Script to change the subnet and vlan.

  Hello

  Please can anyone help with a script to change the subnet and VLANs on all the esx host in a cluster for the vmotion and management network interface?

  Thank you

  Astra

  I guess it worked because you pasted an out front, so:

  Get-Cluster mycluster. Get-VMHost | Get-VMHostNetworkAdapter | where {$_.} PortGroupName - eq "VMotion"} | {} %
  Game-VMHostNetworkAdapter - VirtualNic $_ - IP $_. IP - subnet mask "255.255.254.0" - confirm: $false
  }

  I guess that makes still out:

  Get-Cluster mycluster. Get-VMHost | Get-VMHostNetworkAdapter | where {$_.} PortGroupName - eq "VMotion"}

  2 vmknis right?

  If Yes, then it should work I think.

• Existing vSwitch using and VLAN

  Hello

  I was wondering if it was possible to configure Lab Manager to use an existing vSwitch and VLANS configured in vCenter rather than create its own switch and VLAN?

  Thank you.

  Unfortunately not.  You will need to let LM create and manage their own groups of ports or switches.

  Note that:

  -When you bind a physical network to a vSwitch/vDS, LM creates a port group to represent the network (it also has an 'LM' tag in vCenter)

  -If you deploy a configuration "reserved", he made a vSwitch or vDS port group to represent the fence... and limit network traffic.  Again, when you look in vCenter, there should be an 'LM' tag to the object.

  Kind regards

• Configurations of VMotion and VLAN

  Configurations of VMotion and VLAN

  ESXi 4.0 / 4.0 vCenter

  Can someone explain how to configure the ports VMotion using VIRTUAL LANs.

  Here's the design;

  Two network adapters for teaming on a virtual standard switch 0

  A network for management and another network for VMotion traffic

  The ports management group is on VLAN 103 and its default gateway is set to the network VLAN 103

  When I add a for VMotion VMkernel port group and configure the network, and I use the gateway of 103 VLAN by default I can't vmkping the other interfaces for VMotion similar configuration.

  If I change the default gateway settings and use VMotion gateway, then bad things happen, i.e. lose connectivity to the service console.

  Thanks,-Jeff

  Both an eon of ar sthjey the same physical segment (i.e., the plughed in the same physical switch) there will be no need for a gateway for the vmotion network address.

• Difference between groups of ports and VLANS

  Hi guys

  I read ESX Admin guide 2 times till now, but I still don't know what exactly is the difference between groups of ports and VLANS? I understand, but if someone asks me this question I will not be able to respond with confidence.

  Network also label: my understanding is that it's just label No technical significance in configuration?

  Thanks in advance

  One VLAN is one of the many settings that you can configure for a group of ports, you also have the tabs security, Traffic Shaping and consolidation of NETWORK cards.

  Port group name, you associate you a VM port group must be placed systematically on other hosts if you want to migrate or virtual failover from one host to another.

• Question about VMKernel iSCSI traffic and VLANS

  Hello

  This is a very fundamental question that I'm sure I know the answer too, but I want to ask him anyway just to reassure myself.  As a precursor to my question, the configuration of my ESX infrastructure is best described here: http://www.delltechcenter.com/page/VMware+ESX+4.0+and+PowerVault+MD3000i.  Or more precisely, we have two controllers MD3000i.  Each controller has two ports and each port is configured on two different subnets, with every subnet connected to the different switch.  ESX host are connected to two switches.  The only difference for the guide, is we have two MD3000i configured the same, connection to the same switches.  Each MD ports is configured on the same subnet, but different IP addresses.

  At present, we are in the process of upgrading our two iSCSI switches of humble Dlink DGS - 1224T to Cisco 2960 T of.  The switches have been and continue to be dedicated to iSCSI traffic, however, I'm trying to set up VLAN s on the side of the switch.  Originally, we used the default VLANS on switches, however, after you have added an another MD3000i, noted the Support Dell best practices is to separate each on its own subnet and VLAN MD3000i iSCSI traffic. This would result in iSCSI 4 VLANS, two on each switch and two for each MD3000i.  Firstly, is this in fact of good practices?

  Second, if I migrate preceding 4 iSCSI VLANS, as each switch port will actually be an access port, will there need to complete the VLAN ID field in the VMKernel configuration page? Presumably, this field is used when the tagging VLAN is used, but as our switches do not need any other rocking trunk (as they are dedicated to iSCSI traffic), there should be no need to fill?  I guess it would be prudent to keep the two existing subnets, create two new subnets and make changes to an MD3000i and connection of the ESX host.  Provided the switch and switch ports has been appropriate configured with VLAN on the right, the rest should be transparent and he wouldn't be Intel VLAN in all ESX hosts?

  Would be nice to get answers and thank you in advance!

  Gene

  (1) Yes, it is best practice for ESX iscsi, having an independent network and vlan for iscsi traffic.

  (2) No, there is no need to mention anything in the area of vlan, if you use an access port. Its a mandatory thing than a choice. If you supply the id vland with access port, it loses connectivity.

  Please explain a bit why you need to create two different virtual local networks for each MD3000i. You are going to use several on the same ESX box iscsi storage? Alternatively, you use only a single iscsi and use these 4 ports for the same single VMkernel interface?

• Independent migration of LWAPP and dynamic interfaces on the controller 4404

  We are currently migrating from a stand-alone environment. Access points currently take wireless clients and put

  their right in separate VLANs that SSID that they associate with. Each SSID is another customer

  So we are essentially acting as a service provider. We try not to get involved with the functions of layer 3.

  Each range of IP of SSID is ordered by a customer or a third party. So far, we didn't specify an address from DHCP server, the client is getting on one VLAN and it is up to the customer to assign their own intellectual property details.

  Now that we're migrating to LWAPP I found the following-

  -J' need to specify an IP address for each dynamic IP address for each WLAN

  -J' need to specify a DHCP server for each dynamic IP address for each WLAN

  Because I have no control of the PPE, I put in the details of false dynamic Interface but the correct address of the DHCP server.

  It seems to work.

  My questions are as follows:-

  1 / is there a way I can simply place clients in a VIRTUAL LAN using LWAPP equipment so we didn't

  get involved with Layer 3 configuration?

  2 / I noticed when I got a DHCP address on a test laptop client, the DHCP server is 1.1.1.1. The only thing in the network that I know is the virtual IP address of the controller that is used for groups of mobility. Is this normal?

  3/on the controller is the query DHCP has passed from the management or the dynamic interface?

  3 / What is the IP address of the dynamic interface actually used for? At the beginning I forge the DHCP server use it as a source, but my setup works with a bogus address.

  Welcome to the world of LWAPP! It's a pretty confusing to get, so I hope I can answer some of your questions.

  Before directly answering your questions, I want to give you a little if a glimpse as to how traffic flows in LWAPP environment. All traffic LWAPP is placed in a tunnel to the controller (this is why LWAPP APs is no longer need to switch trunk links). Traffic is désencapsulé and sent to the appropriate interface switching environment (management or dynamic). The source address for traffic is changed to match the control interface for traffic must return to the controller in order to get the customer. For example, IP addresses are required on the controller.

  1. think of the controller as a layer 3 switch that masks the identity of its customers. By sourcing all traffic from itself, it ensures that all traffic comes back to him, how it forwards traffic to the client via the LWAPP tunnel. False addresses you entered are actually being used on the network, then you will want to register those with the people in charge. If someone uses this address, it will eventually drop your wireless network.

  2. it is normal. The virtual IP address is also used for DHCP service. Because the controller blocks all emissions, it must the DHCP proxy for each client, where the virtual IP address as well as the need to specify the address of the DHCP server.

  3. I don't know what interface it gets passed on. Maybe someone else can answer.

  4. see above for a description of what it is.

  One last thing. What, exactly, are these fake addresses to which you refer? They are real addresses which comes with? They correspond to the VLAN that you places on? You give them suitable default gateways?

  Don't forget that by configuring these, they are real addresses on your network that you should be able to ping. And yet once, if the address is duplicated on the network, it has the potential to get to the bottom of your wireless network.

  Let me know if this can help, and if you have any other questions!

• Use HREAP SSID and vLAN

  Hello

  I have currently a small deployment wireless using LWAPP 1141 against WISN controllers. The controller is configured with a SSID against a dynamic interface.

  For the mobility of the user, the company wants to use one SSID for the movement of personnel between offices

  New Office Online to use 3502 configured as of HREAP and local CAPWAPs to next mode switching.

  My understanding is that the CAPWAPs require a virtual interface on the controller to CAPWAP > traffic controller. Requires a dynamic interface for users of the site of HREAP setting on the controller? If this is not the case, how an SSID on the controller are mapped to the vLAN on the remote site?

  Thank you

  David,

  No problem, so review your comments below really all what you need to do is the following.

  Once the SSID is set to H-HARVEST of local switching, and the AP is set in Mode H-REAP follow these steps:

  -Under AP Configuration click the H-REAP tab and activate the socket supported VLAN

  -The value VLAN native 797 and click on apply

  -Under AP Configuration click the H-REAP tab click on mappings of VLAN

  -Enter the respective VLAN for the SSID is shown if they are different from

  -On the remote switch port Configuration of AP as a port Trunk just like you did with the WLC port (797 of VLANs allowed native and 301.)

  The Group REAP H is more important if your use 802. 1 x or authentication EAP type where a radius server is used. You can create a Group H-HARVEST to implement if you want even if you do not use this authentication method.  In regards to the WLC knows it remote. I don't think he cares.

  You can see examples of my 3 screen shots attached.

  I hope this helps... Please evaluate the useful messages.

• SFE2000 and VLAN

  Before we begin, I want to say that I saw "' responses to my question, but never exactly what I'm looking for, so I create a new post.  I'm not a network engineer, so please forgive my ignorance.

  We are a public library.  We have a network that includes a number of branches, through the central site of the main library.  We show an ASA firewall. We have a Cisco3825 for local and a series of Cisco2800 Internet connection.  We use a system of 192.168.xx.xx, using DHCP network.  We have a number of PCs that are on the network access to the public and they are locked by using various software that prevent people to do much except get Internet.

  What we want to do is to put the public pc in their own network, always using our Internet connection, but not allowing them to see or access one of our 192. addresses.

  We bought a Linksys SFE2000 and it is my understanding that if I use it as a layer 3 switch, we can do what I suggested above.  However, I get so far and I reached my level of incompetence!  We want that all the public pc to come through the SFE2000 and although about allowing the public to use a wireless connection (but that is located).

  Can anyone offer suggestions or point me to a site that will help me?  Thanks in advance and again, sorry for my ignorance.  I look forward to hearing from anyone.

  Well, the router must have at least one interface. If the interface is used otherwise you can simply run it through the router as well.

  If you want to use the features of the ESF L3 basically configure you the VLAN as I've mentioned before. You enable L3 on the ESF, then you configure filtering on the ESF for the VLAN 'public '. Drop everything that goes in your charge of private VLAN.

  The problem is the connection to the router. We must define a new IP subnet for routing between the CPE and the Cisco. So, basically you will need a 3rd VLAN to connect with the Cisco. You can use a very small for this IP subnet if you wish. For example, add VLAN3 with IP address 192.168.99.101/255.255.255.252. The port on the Cisco configure IP address 192.168.99.102/255.255.255.252. On the ESF, set the default gateway 192.168.99.102. Who should route all internet traffic to the Cisco.
