4900M connection to HP Virtual Connect Flex 10

Trying to connect a HP-C7000 blade server with a Virtual Connect Flex 10 connection with 10Gb links to a Catalyst 4900M.
I have no control of the HP side. From the HP guide, we are following "HP Virtual Connect Ethernet Cookbook" "Scenario 1:5 - VLAN Tagging (802.1q) with Shared Uplink Set (SUS) with Link Aggregation using LACP (802.3ad) - VMware ESX"
On the 4900M, LLDP sees the Virtual Connect and LCAP up with 2 active links. Show interface on Ten1/1, Ten1/2, Port-Channel 1 shows 0 packets input.
Basically, we can not get any packets from the HP Server/VMware server side through the Catalyst 4900.
IOS version: 12.2(54)SG
Switch ports are as follows:
interface Port-channel1
description HP FLEX-10-VC
switchport trunk allowed vlan 4,8,10,11,16,22-24,69,99-101,156,192,300,500
switchport mode trunk
switchport nonegotiate
spanning-tree portfast trunk
interface TenGigabitEthernet1/1
description HP FLEX-10-VC
switchport trunk allowed vlan 4,8,10,11,16,22-24,69,99-101,156,192,300,500
switchport mode trunk
switchport nonegotiate
spanning-tree portfast trunk
channel-protocol lacp
channel-group 1 mode active
interface TenGigabitEthernet1/2
description HP FLEX-10-VC
switchport trunk allowed vlan 4,8,10,11,16,22-24,69,99-101,156,192,300,500
switchport mode trunk
switchport nonegotiate
spanning-tree portfast trunk
channel-protocol lacp
channel-group 1 mode active

This command starts passing traffic on all of the VLANs using the trunk. If the Flex Connect sees layer-1 come up but is unable to pass traffic it may think the interface is not working. I enable this on trunk connections to VMware hosts and Flex Connect interfaces. It is possible disabling portfast will not cause problems for the Flex Connect interfaces. You can test this in your environment and see what works.

  • Upgrade c7000 to virtual connect flex-10/10D

    We have basic c7000 enclosure with 1 GB pass-thru modules (bay 1,2,5,6,7,8 for networking and brocade pass-thru for Fiber Channel - bay 3,4 for storage.  Have 5 bl460c Gen8 Blades.  Trying to upgrade to virtual connect flex-10/10D on the networking side.  Is their a way to import the existing server network information into the initial virtual connect domain?

    How I know, for work with VC Flex-10, you need to use separate switches between P4000 and chassis.

  • Connecting Flex 2 To Data Sources

    I have order flex 2 (out of my own pocket) so I can learn how
    to use it. Hopefully I should have it in the next day or two.
    It seems that once I get going, the truly cool stuff will be
    connected to some sort of data source.
    Any suggestions for getting inexpensive data sources set up
    so I could learn that piece of flex?
    Currently my web host allows a SQL database, but I have not
    really made use of that feature.
    Paying for something like Cold Fusion out of my own pocket is
    a little to much for me. Paying for the upgrades for Production
    Studion and the old Macromedia Studio 8 will suck up most of my
    play cash in the next year or so.
    Thanks
    Mathias

    well you dont need to purchase anything to write .net and
    even ASP could fill the role of server side technology for most
    flex apps. In fact one nice thing about IIS is that you can write
    your server side script in javascript which is very similar to
    actionscript which is nice and if you need to do client side script
    you can swap your javascript functions back and forth in your
    client and server side scripts. Also you dont have to use MS
    technologies to talk to their DBs, you could use whatever script
    enviroment that your host has to offer. As far as rendering XML you
    can use dataBinding objects on the host or even just render it your
    self like
    var rName = ""+ sqlObject("Record_Name");
    var result= "";
    result= "<xml>\n\r<name>"+ rName+
    "</name>\n\r</xml>"
    Response.write(result);

  • How connect FLEX and SAP R3 via RFC

    Hi all
    Can anybody tell me, how to connect the SAP R3 and FLEX via RFC.
    Is this possible or can only be via webservice?
    Regards and thanks,
    morojan

    Well in theory you could build a flex component that uses the RFC library to call SAP (and viceversa) but it sems like a lot of trouble when you can just use the existing HTTP/XML methods already available.

    Depending on what you're wanting to do, you can either use a
    Repeater with
    an Image or custom component that contains an Image or you
    can use a List
    based component to display an Image or custom component with
    an Image (or
    SwfLoader, or Loader) in it. There is literally a ton of
    stuff about this
    in the Help. Here are some places you may want to try:

    Help>Help Contents>User Interfaces
    - Using Data Providers and Collections
    - Controls
    - Image
    - SwfLoader

    - Using Item Renderers and Item Editors
    - Dynamically Repeating Controls and Containers

  • LMS 3.2 User Tracking 10GE trunk to HP BladeSystem c7000 w. Virtual Connect Flex10

    Hi All,
    situation:

    Cat6509 w. 4 port 10 GE module connected with trunk to
    HP BladeSystem c7000 Enclosure
    with
    HP Virtual Connect Flex-10 10Gb Ethernet Module
    with
    #20 of ESX servers, Citrix
    UT settings: "config trunk for end host disc. = enable on this trunk."
    No show for connected MAC's of the server and end hosts (Citrix sessions).
    Note: this works well for a ESX based DL380 server connected with 1GB trunk to a C3750.
    Why is this not working for this Cat6509 configuration ?
    Is the 10 GE port supported in Campus manager?
    regards,

    Hi Joseph,
    Long time ago I started this discussion about UT support for portchannels. Right now we're on the level of LMS 4.2, do you know if there is any progress made with support for UT on portchannels?

  • Connectivity in flex to oracle using java

    hello,

              Thanks,

    Hi,
    Are you using Flash Builder to build your application?
    Definitely you could connect to web services from flex .
    May be in your case, expose the JAVA class as web services using AXIS(may be) and access it as shown below:
    Sample snippet:
    <mx:WebService
      id="service"
      result="onResult(event)"
      fault="onFault(event)"
      wsdl="http://abc.cd.com/ PhoneNumber.asmx?WSDL/>

  • OVM 3.0.2 - Network Bandwidth with HP Flex-10

    Hi All,
    In 3.0.2, we can segregate the various network traffic through different network adapters. Using HP's virtual connect Flex-10 hardware, we can carve up a 10 Gb pipe for the different nics.
    I would like to find out how you would carve it up given the 5 networks in 3.0.2:
    Server Management & Cluster Heartbeat = 0.5 Gb
    Live Migration = 1.5 Gb
    Virtual Machine = 3 Gb
    Storage = 5 Gb
    Or would you share the bullk of the pipe like so:
    Server Management & Cluster Heartbeat = 0.5 Gb
    Live Migration & Virtual Machine & Storage = 9.5 Gb
    Given that HP's Flex-10 has no QoS, would this be a good idea to share traffic on the same nic (given the various networks are on seperate vlans)? The 2 Flex-10 modules we have connect to seperate Nexus 5000 switches but I'm still investigating if QoS can be done from the Nexus end.
    Thanks.

    Hi Avi,
    Its mostly to house EBS 12.1.3 virtual machines, 1 app tier and 1 db tier, for each environment like prod, dev, test etc. Very little live migration on a day-to-day basis. Even when taking host offline, I could probably afford to live migrate one vm at a time. So its mainly vm and storage traffic. vm's use virtual disks stored on an nfs repo while each guest hosting an oracle database has a seperate direct nfs mount to its own volume on the NetApp.
    We're currently using 2.2.2 with traffic for dom0 (2 bonded nics) and domU (2 bonded nics) without vlans. Looking to move into version 3 of OVM down the road and would like to seperate traffic further using vlans as well. Most documentation I've come across regarding flex-10 is with vmware but the similarities are there with OVM 3.
    Problem with flex-10 is carving the bandwidth up isn't exactly very efficient as it can't tap the unused bandwidth if one nic is saturated. While on the other hand, sharing the pipe may have contention issues. Of course my environment probalby doesn't come close to saturating the 10 gb pipe.
    But would like to get other views as to how they would desgin their flex-10 environment with OVM 3. Is 0.5 Gb plenty for mgmt & heartbeat? Seperate vm and storage and migration? Or maybe some other configuration? Any ideas thrown up would be most welcome.
    Thanks.

  • Wish To Use Flex 2 For My University Project

    Dear All
    I am a mature student studying a Computer Science Degree in
    the UK .
    For my final year project, I am creating a Stock Market
    Simulation with a Database back end (e.g. SQLite ?) and some kind
    of front end, both to be run a a stand-alone machine.
    I have a 28 weeks to design, build and run it for my
    supervisors. I would like to push myself academically by building
    the software using Flex 2, for the GUI and even to carry out any
    calculations or processing needed for the simulation to operate
    correctly.
    My questions are
    1) Is it possible to create the simulation as I can find no
    definitive way to connect Flex 2 directly to a database back end in
    a similar way to ADO.net?
    2) If it is possible which book do you recommend to get the
    best and quickest results out of Flex 2?
    Thanks In Advance
    Steven

    You are correct, Flex does not natively connect to any
    database. Further, security restrictions on both the browser and
    the Flash Player prevent access to *any* client resources, such as
    the filesystem.
    So if you use standard Flex, you will need some back-end web
    technology. This can be almost any platform/language you choose.
    Now, the newest, coolest thing in the Adobe world is AIR. AIR
    applications can be written using Flex, Flash, HTML and javascript,
    and have full access to client asseets. AIR is essentially an
    internet delivered desktop application.
    AIR has SQLLite database built-in.
    AIR is currently in public Beta. I do not know what will be
    available as far as non-commercial or educational licensing when it
    is realeased.
    I don't have a book to recommend, but here is a partial list

  • FLEX WITH BLAZEDS/LCDS

    What are the roles and responsibilities of flex developer in blazeds application?
    Actually i am a flex developer by profession and having 2.5 years of experience of developing client side flex application with backend support of php using AMFPHP.Till now,our team member(only flex) interact with the backend team members(php members) and got the data as they want.
    But now i want to connect flex client to java using BLAZEDS OR LCDS ES , so i want to know that is the procedure will remains the same that flex developers now interact with the backend java developers as they did with php developers or flex developer have to manage the server of their own and write java code themselves.
    Thank you in advance.........

    It is usually common for teams with multiple developers to have a division of responsibilities between back-end (Java, PHP, .NET, etc) developers and front-end (HTML, Flex, Silverlight, etc.) developers. This makes it easier to divide up the work on a clear "boarder," so both sides can work in tandem with little interference.
    That being said, it may be beneficial for front-end developers to have a little bit of flexibility to make minor changes to the back end if the project is not clearly defined ahead of time. And as always, the feedback loop between designers, front-end developers, and back-end developers, should be kept as short as possible to achieve the greatest flexibility.
    Disclaimer: These are my own opinions based on how I work with my own team. Results may vary.

  • Flex 2, FDS 2.5 and CF 8: Still can't execute any kind of WebService!!!

    Hi everyone,
    I am starting to retract my brain from an intense 2 days to figure out how to use Flex with Coldfusion. I am using Coldfusion 8 Beta (this part is good, don't need help for CF itself). I am also using Flex Builder 2 (with chart but this not the topic). I installed FDS 2.5 before to install ColdFusion 8 but I think CF8 have is own FDS or something like that... anyway, it might help to mention it!
    Well, I tried HTTPService, RemoteObject, WebSer vice - NOTHING WORKS!!! Argh! Did I mention I spent 2 days? ;-)))
    Well, I start with the basic: a login form with an email (as a username) and a password to be validated. I have a CFC to do the validation and return a simple message (string): "OK' when it is valid and a custom message when it is not valid; depending if it is the password and/or the email which is not valid.
    I always got an error. Since the error is different depending of the method I use, I will explain the latest method I used in this message and try to concentrate on that method specifically! The method is WebService and here is the error:
    faultCode:Server.Error.Request
    faultString:'HTTP request error'
    faultDetail: 'Error: [IOErrorEvent type="ioError"
    bubbles:false cancelable=false eventPhase=2
    text="Error #2032: Stream Error . URL=http://localhost:8501/iDashboard/login.cfc"].
    URL: http://localhost:8501/iDashboard/login.cfc'
    Any help will be very useful!!!
    Thank's
    P.S.: I succeed to execute a HTTPService only if I call a XML file.
