• 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)?

• Wiring of VMotion and VLan question...

  Hello

  I understand the VLANS and how they work, but I'm not really a 'network' guy and I have a few questions...

  My servers are dl380 g6 with 8 network ports. I intend using two for console service, two for vmotion and the other 4 for my virtual switch of production. I know there is no way of vswitches configuration, but it's my game to date plan.

  My question is how can I configure a vlan and segment the traffic for vmotion? I have 4 ports on my physical switch that I put aside for this vlan vmotion. How can I set this up? Wwhat can I do on the switch and how do I have to create a separate subnet in the DNS? ABLES

  My plan is to pass the cables from the ports on esx hosts I put aside for vmotion to the physical switch ports...

  I'm not too sure about that...

  Thank you! points will be awarded to anyone.

  Hello.

  My question is how can I configure a vlan and segment the traffic for vmotion? I have 4 ports on my physical switch that I put aside for this vlan vmotion. How can I set this up? Wwhat can I do on the switch and how do I have to create a separate subnet in the DNS? ABLES

  What kind of physical switch are you using?  Here is a link to the Cisco documentation to create the VLAN on Catalyst switches.  Create a layer 2 VLAN and create VMkernel interfaces with the appropriate IP addresses.  Don't worry about DNS or Routing and keep things simple, if you can.

  Good luck!

• 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.

• 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?

• 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.

• Cisco ACS 5.1 and RSA Authentication Manager 6.1

  Hi all

  We recently had a Cisco Secure ACS 1120 and I improved the Unit 5.1 5.0 with all your support

  Now, I need to integrate Cisco ACS 5.1 with RSA Authentication Manager 6.1. I have config file of RSA ACE Server successfully downloaded and exported to 1120 ACS.

  I also added as NetOS Agent ACS in the RSA server during the process, I found a few warnings. The ACE Server is not able to resolve the IP address to the name (is it necessary?).

  I have not created any file of secret key for communication between FAC and RSA and I used encryption is FOR.

  Now, when I log into ACS and search for devices in the identity store sequences I am not able to get Sever Token RSA.

  Let me know what was wrong, where can I fix and also please tell me what is the communciaction between the RSA and ACS?

  Hoping that you guys help me as usual when I'm in a hurry...

  Sree

  Were you able to successfully create the RSA identity server. After selecting the sdconf.rec and you press on submit what happened? The RSA instance created OK?

• 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...

• Back on the cisco ASA 5500 series and PIX 500 series

  Hello

  I fund a site www http://www.searchsecurity.de/themenkanaele/plattformsicherheit/schwachstellenmanagement/allgemein/articles/106752/ (only in German). I have read that it is possible to make a denial of service on cisco PIX 500 series and series 5500 ASA, when the TTL value is enabled.

  How can I check that? or solve the problem?

  I thank you,

  Mary

  What version of the code you run the Pix or ASA. Refer to the "Products affected" section for more information on versions and the products concerned. This should point you in the right direction.

  Also, listed in the URL is bypasses and fixed Versions that you may want to check.

• Get pixels layer setting value and coordinated arbitrary XY

  So it drives me crazy. I have searched the forums and found promising clues, but nothing seems to work.

  I'm in an iterator to float for the active layer (suites. IterateFloatSuite1()-> iterate_origin()).

  I spent my layer inside, like a PF_LayerDef parameter.

  How can I get a pixel of it value?

  What I want to do, it is something like this:

  out = getPixelValue (id-> layer.data, xCoord and yCoord);

  I am that simply approaching the wrong way?

  Surprisingly, any help would be appreciated.

  Thank you.

  Hello

  If you go in the direction of suites, you can try PF_SAMPLINGSUITE and subpixel_sample.

  The manual way would be:

  PF_PixelFloat getPixel (PF_EffectWorld * inputP, const A_long XY, const A_long) {}

  return = * ((PF_PixelFloat *) ((char*) inputP-> data + (y * inputP-> rowbytes) + x * sizeof (PF_PixelFloat)));

  }

  so with a 10 pixel, [10], you will get:

  * ((PF_PixelFloat *) ((char*) inputP-> data + (10 * inputP-> rowbytes) + 10 * sizeof (PF_PixelFloat)));

  }

  See you soon,.

• 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?
