• 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!

  (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?

• 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...

• 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

• 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.

  Hi me yedess apple that i 6 s phone few days back knowing have the best phone in the world since the day I bought that I have questions on screen and when I went to the service centre they said they're going to update, I bought they updated after that I have the same problem now they say they're going to fix very terrible situation for apple this new product which has manufacturing defect they will repair, I asked to change device they deny because they want to fix m single i face the problem of the first day of the customer are powerless and that they only make just crazy.

  It's what warranties are for. If you bought the phone from Apple or an Apple authorized reseller, iPhone, you have 14 days to return it for a refund. After that the Bank should replace the phone. If you did not buy from Apple or a shop authorized, you must respect the terms of this store. However, Apple will always replace the phone, if you contact them directly.

• Trying to follow a question re ITunes and shuffle.  Links on the email no longer work.  How can I do this?

  Why Apple Support community-is such a maze.  Surprisingly, after much effort, I have a question was asked and answered to (helpful but not completely).  In trying to follow up, I have found no direct link in my email, no way to find my name in the communities of support and no way to push my question to the next level.

  I know now how to disable "shuffle" in my ITunes on my IPhone.  Is not very intuitive, as some helpful person has said.  Also, the highlight on the button 'shuffle' is unnecessarily pale.  So now, because since then, shuffle returned requiring manual turn off again, is there some default to shuffle?  I've experimented with compensation the ITunes program and with the phone turned off/on.  Neither returned me shuffle.

• Question about CR and LF

  Hey guys,.

  Quick question on LF and CR. As you can see I'm LF and CR of writing to a text file and because directly.

  

  However, I don't get the CR at the time where I read it. Why is this? Is it because Windows ignores the CR?

  Thank you

  Hi dora,

• 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.

  See you soon

• 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.

  Thank you

• 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)?
