Cisco ACE 20 - sticky radius attribute not working

Hello to you all
I need your help. I´m trying to create a sticky group applied to my auth serverfarm based on the calling-station-id attribute, but for some reason when I apply the configs, I get not replies from my rservers. I´ve checked the radius servers, and no packets are getting to them. For some reason, when I create the sticky group the ACE 20 doesn´t distribute the traffic at all.
The service-policy is inservice, all the rservers are operational, but there´s no replies to my authentication requests, and no entries in the sticky database.
My current configs:
ADMIN context:
resource-class RADIUS-STICKY
  limit-resource all minimum 0.00 maximum unlimited
  limit-resource sticky minimum 10.00 maximum unlimited
context context-radius
member RADIUS-STICKY
CONTEXT-RADIUS context:
serverfarm host RADIUS-AUTH
  predictor leastconns
  probe RADIUS-PROBE-AUTH
  rserver RADIUS-01
    inservice
  rserver RADIUS-02
    inservice
  rserver RADIUS-03
    inservice
sticky radius framed-ip calling-station-id RADIUS-AUTH
serverfarm RADIUS-AUTH
timeout 5
policy-map type loadbalance first-match RADIUS-AUTH
  class class-default
    sticky-serverfarm RADIUS-AUTH
Am I missing anything?
Best wishes

I figured it out
The loadbalance policy-map has to be set has a L7 Radius policy map:
policy-map type loadbalance radius first-match RADIUS-AUTH
  class class-default
    sticky-serverfarm RADIUS-AUTH
It now inspects the Radius packets and is able to apply stickiness.

    Hello,
    We will not be able to determine why your SSL terminated connections fail with only your config.  You may want to take a look at a similar thread where someone else was having problems with IE and SSL termination, but Firefox worked fine.  It also includes a solid action plan you can use to gather data needed to diagnose root cause.  That thread can be viewed at the following link:
    https://supportforums.cisco.com/thread/2025417?tstart=0
    Also, the ACE software you are running is extremely old now and very buggy.  I would strongly urge you to upgrade to A2(2.4) as soon as possible.  It will help you avoid some headaches as you move forward.
    Hope this helps,
    Sean

  • ACS 5.5 Radius Attribute not listed in Radius Directory

                       Hello Community,
    iam on the evaluation on Cisco ACS 5.5, and iam trying some scenarios for my company.
    I have to authenticate a ip phone . here i need one VLan tagged and one vlan untagged.
    In the authorization profile u can add the Radius Attributes, we got hp switches and i need the attribute  with the ID-56, but this ID ist not listed in the Authorization Profiles--> Radius Attributes-->select Part.
    But it is listed under system-administration->Configuration-->dictionaries-->Protocols->Radius--> Radius IETF
    come somebody tell me how i can selct this Attributes under Authorization Profiles--> Radius Attributes-->select Part. ??
    Thanks a lot
    regards

    Hi
    As you are using HP switches, certain advanced use cases, such as those that involve posture assessment, profiling, and web authentication, are not consistently available with non-Cisco devices or may provide limited functionality, and are therefore not supported with non-Cisco devices.
    For more information regarding Authorization profile configuration, please go through the following link:

  • Cisco css http keepalive is not working with GET command

    Dear all
    i have Cisco Css connected to Dell Server (via switch)
    Cisco CSS - 192.168.1.3 and Dell Server - 192.168.1.5
    Dell server is setup with windows 2009R2 and Apache HTTPD is version 2.2
    This server is dedicated to host multiple doamins with Apache lik
    www.abc.co.uk
    www.xyz.co.uk
    Now the clinet wants to setup the http keepalive  with specfic web page like /testpage.html  for all these domains. i have teseed with single URI. it is working the comamnds are
    config)# service serv1
    (config-service[serv1])# ip address 192.168.1.5
    (config-service[serv1])# keepalive type http
    (config-service[serv1])# keepalive method head    ( get i have not used due to hash mismatch with apche server, if i use GET it is not working)
    (config-service[serv1])# keepalive uri "/testpage.html"
    (config-service[serv1])# active
    It is working with single URI.  but how can i do the same thing for multiple doamins ?
    for multiple doamins do i need use script ? or can i use with commands ?
    if i need to use script the script is
    !no echo

    but this script is not working
    my question is:
    1.do i need use script only to setup http keepalvie with webpage for multiple domains ?
    2.with out using script is there any solution like CICSCO  CSS commands  to setup http uril for multiple domains which are on 1 singl server.
    please help me asap

    Hello Muhammad,
    If you wish to use multiple domains for a URI  keep-alive check, and perform a HEAD request what Daniel mentioned is  correct.  You have to use a scripted keep-alive check on the service.  However, you should not use the default "ap-kal-httptag" script to do so  as it's limited to only 1 website (unless you modify the script).  You're best bet would be using the "ap-kal-httplist" script on the CSS  as it allows the checking of 2 different websites along with a webpage  to check for each site using HTTP HEAD method.
    !no echo
    ! Filename: ap-kal-httplist
    ! Parameters: Site1 WebPage1 Site2 WebPage2 [...]
    ! Description:
    !    This script will connect a list of sites/webpage pairs.  The
    !   user must simply supply the site, and then the webpage and
    !   we'll attempt to do an HTTP HEAD on that page.
    ! Failure Upon:
    !   1. Not establishing a connection with the host.
    !   2. Not receiving a status code 200 on the HEAD request on any
    !      one site.  If one fails, the script fails.
    ! Make sure the user has a qualified number of arguments
    if ${ARGS}[#] "LT" "2"
            echo "Usage: ap-kal-httplist \'WebSite1 WebPage1 WebSite2 WebPage2 ...'"
            exit script 1
    endbranch
    while ${ARGS}[#] "GT" "0"
            set Site "${ARGS}[1]"
        var-shift ARGS
        if ${ARGS}[#] "==" "0"
            set EXIT_MSG "Parameter mismatch: hostname present but webpage was not"
            exit script 1
        endbranch
        set Page "${ARGS}[1]"
        var-shift ARGS
        no set EXIT_MSG
        function HeadUrl call "${Site} ${Page}"
    endbranch
    exit script 0
    function HeadUrl begin
    ! Connect to the remote Host
    set EXIT_MSG "Connect: Failed to connect to ${ARGS}[1]"
    socket connect host ${ARGS}[1] port 80 tcp 2000
    ! Send the head request
    set EXIT_MSG "Send: Failed to send to ${ARGS}[1]"
    socket send ${SOCKET} "HEAD ${ARGS}[2] HTTP/1.0\n\n"
    ! Wait for the status code 200 to be given to us
    set EXIT_MSG "Waitfor: Failed to wait for '200' on ${ARGS}[1]"
    socket waitfor ${SOCKET} " 200 " 2000
    no set EXIT_MSG
    socket disconnect ${SOCKET}
    function HeadUrl end
    Rather  then modify the default "ap-kal-httplist" script on the CSS I would  simply define the arguments within the service configuration itself.   Something like the following (using your service example):
    service dell-192.168.1.5
    ip address 192.168.1.5
    keepalive type script ap-kal-httplist "www.abc.co.uk /testpage.html www.xyz.co.uk /testpage.html"
    active
    As  long as the server is configured to reply to host headers, and the page  is configured to retuen a "200 OK" the above service configuration  should work. If there are any errors simply run "show service  " to view why there was a failure. If there is a  failure, and the output from the command specified shows a line number  run the following command against the script to view at what point  (line) did the failure occur:
    show script ap-kal-httplist line-numbers
    Hope this helps!

  • Key figure Attributes not working

    Hi ALL,
    We have an isuue with one of our Planning book. Key figures which are supposed to be open for editing are  showing as output only and key figures which are for output only are showing as open for editing.
    I went to design mode to tried to change in manually , if I chane one row attribute all rows are getting changed.
    I found a macro which assigns Key figure attributes which I tried to activate but still not working. We are using SAP SCM 4.1 Version.
    Can any advice on this?
    Sivarama

    Thanks Problem is now solved. Looks like some has made changes in the design and there are macros which are working and as you said they might be conflicting. I changed the design which was working weired yesterday when I tried to cande one row attribute and all rows are getting applied, this worked fine today. And I deactivated the macro which is working on some row attributes and activated again.
    I am not very clear what went right but working.

  • Container-Managed Transaction Type Attributes not working as expected

    I am having a problem with the container-managed transactions not working as expected. I have 2 methods that work as follows:
    MethodA{
    for(a lot)
    call MethodB;
    @Transaction Type = RequiresNew
    MethodB{
    EntityManager Persist to database
    I want the code in MethodB to be committed to the database when methodB returns. The problem is that I am running out of memory and MethodA is failing. When methodA fails after numerous calls to MethodB nothing is persisted to the database.
    It is my understanding that when using requires new transactions that a new transaction is started for each call to the method and ends when the method returns while the calling method transaction is suspended.
    How am I misunderstanding the requiresNew transaction attribute. What can I do to make a batch insert into my database that will not run out of memory (commit when a methodB returns)?
    Thanks in advance.

    The problem is that EJB invocation semantics for security, container-managed transactions, etc.
    only apply when an invocation is made through an EJB reference. In your case, you are directly
    invoking the implementation method from within the bean. The EJB container has no idea that's
    happening. It's no different than invoking a utility method.
    In order to get the behavior you'd like, you need to retrieve a reference to your own bean and invoke
    through that. You can use SessionContext.getBusinessObject() to get the EJB reference for the
    business interface through which the method in question is exposed.

  • 5.5.2 'Paste Attributes' not working?

    I just upgraded to Premiere Pro 5.5.2, I'm on Mac OS 10.6.8, now paste attributes has no effect on the target clip in the timeline. Any clues?

    Hi Chris
    I don't have an answer with you, I just did some more comparisons, creating a completely new project with EX1, JVC HM100 (also the EX1 codec, I suspect same as yours) and Canon 7D H.264 MOV wrapped files.
    I could not reproduce the problem on this new 'test' project.
    So I went back to the Project I was having problems with, and the problem for that sequence can be narrowed down to: copying a clip from Sequence B, pasting attributes to a clip in Sequence A, does not work with my EX1 .MP4 files. However within the same sequence copying and pasting to the EX1 clips works. No other file types are affected and work as expected.
    I then tried to duplicate the problem in my new 'test' project between 2 sequences. I can't get it to fail. So the problem isn't consistent. My real problem project is pretty complex, with a lot of sequences. The file size is approximately 200MB. Not sure if the complexity of the project causes the problem. Try creating a new simple sequence with some test files and see if you can repro the problem, also see if you were copying and pasting within a sequence, or from one sequence's clips to another. I'm wondering if 5.5.2 introduced some issues like this, it doesn't make too much sense but it is real.
    But for now, the problem is slightly solved, I just have to copy a clip into the destination sequence, then copy and paste attributes to other clips. Annoying, but workable. Good luck.

  • Refine Edge Radius Tool Not working

    Hi
    Today my refine edge is not working, although it used to work. When I select with the quick selection tool and click refine edge, when I pick the radius to smooth it out ,it makes a strange thing
    Please Help
    I made a screenshot for the screen,Note  this is still, although I change anything in the Refine Edge Options
    thnx in advance

    I ran into the same problem using the image you posted. Although there was something not right about the edge sharpness and color density where the car met the white surround I was able to get the result you are after.
    This was the sequence:
    1.  Toss the Background layer lock in the trash. It becomes Layer 0
    2.  Cmd + new layer symbol to place a blank layer below Layer 0
         Then, Edit > Fill the blank layer with white
    3, Choose Layer 0 and use the Quick Selection tool to select the car
    4. Choose Refine Edge in the Options bar:
         View Mode > View Mode > Marching Ants
         Brush Size (Options Bar): 200  This is humongous and counter-inuititve, but hang in there.
         Radius 0, Smart Radius
         Paint the white area keeping the + marker a fair distance from the marching ants
         Output: Decontaminate colors (50) New Layer with Layer Mask
    The result is a vastly improved result but the mask is a bit weak in the troubled area. sL
    Option click on the the mask in the Layers panel to reveal the mask
    Curves > Move straight line of Curve to increase contrast via black endpoint
    I think the root of the problem is the lack of edge sharpness in the image. Using Refine Edge when the edge is soft can be pain.

  • Scale Attribute Times and Paste Attributes not working as did before

    Using Copy and then Paste Attributes as I have done many times before upgrading the FCP 5, the option to "Scale Attribute Times" is grayed out and the keyframes are not placed correctly. This happens even if the cips are the exact same duration. I read a post from November that states that this feature is not working is FCP 5. If that is so, has anybody found a work-around or know of a fix?
    Dual 1.25 G4   Mac OS X (10.3.9)   FCP 5.0.1

    The problem is that the content is replaced correctly but the keyframes move (they were originally at the beginning and end and now they are not). The "Scale Attribute times" box is grayed out.
    I just tested this out and, from what I can tell, FCP (5) now needs Timecode to match in order for Paste Attributes > Content (with keyframes intact) to work as we'd like.
    I placed a 10 sec image - with (the default settings of) In at 1:00:00;00 and Out at 1:00:09;29 - in the Timeline. I set keyframes for Scale & Rotation at the In and Out points (100% & 0 degrees -> 200% & 360 degrees)
    When using the Paste Attributes > Content method with a second image having identical timecode In & Out, it works fine.
    However, if the second clip's timecode is not the same - say In is set at 1:00:02;00 and Out set at 1:00:11;29 - then the content will be pasted but the keyframes will not adjust for the new timecode. They remain at the first clip's points (that is,1:00:00;00 and 1:00:09;29).
    So, you can try to match timecode (which isn't always convenient) or you can...
    Select the first clip & copy
    Overwrite/replace the (first) clip with the second clip
    Paste Attributes > Basic Motion (or whatever attributes you're pasting, except Content)
    Or was that a workflow you were hoping to avoid?

    public string LocationName { get; set; }
    public virtual ICollection<Asset> Assets { get; set;}
    Now the issue is that Table has a red squiggle and I am getting the following error: Error  43  The type or namespace name 'TableAttribute' could not be found (are you missing a using directive or an assembly reference?)
    As far as I can tell everything is set up correctly, but this just does not want to work.  It is not only this class, but all of my classes.  The only reference I have in the portable classes is .Net with a target of 4.5.  Everything I read
    says this should work, but clearly it is not working.  I have also uninstalled and installed the entity framework, did a clean and build but with no luck.  Any thoughts?

    Hello Michael,
    >>but once I moved them to the Portable side, I began to have an issue with the data annotation.
    This is by designed, please check the namespace “System.ComponentModel.DataAnnotations.Schema”:
    https://msdn.microsoft.com/en-us/library/system.componentmodel.dataannotations.schema(v=vs.110).aspx, as you can see, only the DatabaseGeneratedAttribute is supported in Portable Class Library.(If a class is supported in PCL, there should be a
     symbol).

  • Sticky load balancing not working  because of Address Translation

              This came up before - see below. I don't understand what the
              soltion is/was.
              WL Server puts it's ip address in the WebLogicSession cookie
              which is an internal address 192.168.201.41
              WL proxy knows WL Server only by an external address like 139.141.38.21. Since
              it does not know of any WLS with an IP
              address of 192.168.201.41, it round-robins the request instead
              of sending it to the primary WLS.
              Any help is much appreciated.
