• Traffic policy - marking DSCP value

  Dear all,

  I'm trying to set up a strategy of traffic on a 2048 P Dell switch. The policy aims to modify the DSCP value of the traffic going to a server specific DSCP 0 to 10 value. Interface 3/0/3 is the PC that connects to the server 10.51.53.16.

  I see incrementation of the output packages to see the switch, but when I perform a wireshark tracing by monitoring the PC port, the DSCP value remains at 0 instead of 10.

  Configuration as follows:

  class-map correspondence class_ccx ipv4

  game of supporting 10.51.53.16 255.255.255.0

  output

  Policy-map test_policy in

  class class_ccx

  Mark dscp-ip 10

  Show running-config interface gigabitethernet 0/3/3

  policy - test_policy

  Direction...................................... In

  Working condition... Upward

  Name of politics... test_policy

  Name of the class... class_ccx

  In the packages offered... 573

  In the packages retired... 0

  See the class_ccx class-map

  Name of class... class class_ccx Type... All the class Layer 3 of the ipv4 Protocol...

  Criteria values - IP address of Destination 10.51.53.16 (255.255.255.0)

  Name of the class... class_ccx
  Mark IP DSCP... 10 (AF11)

  As mentioned, I see no evidence that the DSCP value has been changed for traffic going to my server.

  Thank you very much

  Here's my thought process and the reason that I suggested to check the packets received on the interface of the connected server.

  -The client sends the packet with 0

  -Interface receives this packet and it reflects in the port of destination.

  -Shows OCAP receive packets as the value 0

  -Once the package has been mirrored, the switch sees so it corresponds to the assigned policy and replaces the value 10.

  -Switch transmits packets on the interface of the server.

  At this point the packet on the server side port should be observed with the DSCP of 10 value. We can confirm that by putting up a session session on this interface.

  -If the server is configured to send packets with a different priority, or maintain the priority, the server sends probably packages with a value of 0

  -Switch receives packets of the server returning to the client.

  -Switch has no policy IN this interface, and the DSCP value 0 is maintained.

  -Switch transmits the packet customer facing interface.

  This translates into OCAP showing the value of DSCP 0 to in and out traffic on the customer facing interface.

• Report header update XML with values of table of process model

• Another issue of queues DSCP/QoS/CoS of 6500/7600

  OK... a little confused, thinking, that I know what needs to happen, and what is happening now, but it is true UN-certainty with that I hope that people can help.  Here are the basic configuration:

  A---|6500|--10G--|7604|---10G---|7604|---10G---|6500|---B

  You get the point.  Traffic crossing A-> B or vica versa.

  All the links of the kernel are L3/Routed, not L2/Vlan/.1q/ISL

  Traffic is marked on the Board with a political map of penetration.

  Traffic is confirmed through DURATION that it contains both CoS and DSCP/ToS, leaving the 6500 s two-way headed the core of 7600

  Traffic is ALSO confirmed through extending classes * receipt * on the other side by the 6500, that DSCP is maintained but CoS is gone/0.

  Considering that only 6708 - 10G modules allow apparently dscp values mapped to the queues/thresholds, which leaves me with the research of the queue on the penetration (for VoIP traffic priority) with cos-of-queue / beat mapping as well as output with cos to queue mappings.  Of course, this is not possible (at least on the penetration) if the 7600 are not preserving the CoS on the output of the port.

  This leaves wondering if the 7600 are same queue evacuation traffic based on internal mapping supposed DSCP-to-CoS that is supposed to happen before the queue/Scheduler.  Interfaces are all set up as "trust dscp" right now.  So the CISCO docs should be rewriting CoS to 0 on the penetration and using reliable dscp values to determine internal DSCP, which in turn should be used with DSCP-CoS map appropriate queue on exit... I am a sceptic, what happens really... and unfortunately, have really no way to verify (that I know) because the show on the 6500/7600 commands are fairly primitive about QoS stats...

  Then, we have been re - think about it and thought that maybe the thing to do to solve this problem is to:

  -Trust cos instead of dscp

  -enable transparency dscp (no rewriting dscp) so it is kept on the side of the switch output

  And so by doing this it would be:

  -use CoS to tail of penetration

  -use CoS to output queues

  - And to preserve the original CoS and DSCP/ToS values

  Would that be correct?

  Two other config options I thought were:

  -queue only mode

  -mpls cos spread (although I don't think that would do what I want, but rather simply spread non-existent MPLS EXP bits)

  Any help would be greatly appreciated... I read so many different docs now, my head is swimming

  Couple of caveats-

  (1) all the below apply to pre IOS 15, as I have no experience with which it may be different

  (2) I have not used a 7600, but I used the 6500 much but both share a large number of the linecards and I suspect you're referring to this kind of linecards.

  The main problem is that the CoS value is contained in the 802. 1 q non-native added tag VLANs on a trunk link. But your links are L3 if there is no value CoS to preserve.

  This creates two problems for you-

  (1) input queues. On penetration, the queues are CoS based which means you need to a CoS value to assign packets into queues. On the 7600 s you're obviously not see a CoS value for the reason explained. Now, you can use a political map and a service policy to classify and mark inbound traffic. But, as far as I know, you can set the IP precedence or DSCP marking in a map policy on traffic of the penetration. Some cards like cards ARE for the 7600 support defining a CoS value but I think they are the exception rather than the norm.

  (2) output queues. You are right in what you say, IE. You can trust the DSCP/IPP incoming value and then, assuming that the line card doesn't support based DSCP output queue, the 7600 may derive a value based on the internal DSCP value CoS and then put in the correct output queue.

  Yet once, however, without a trunk there no value written in the packet CoS.

  I entirely agree that it can be very difficult to tell exactly what the 6500 in terms of marking internal etc. This is one of the great frustrations with the 6500.

  Hope some of that helped.

  Edit - the only way that you can trust CoS on penetration as far as I can see is to make the trunk links IE. you use a vlan dedicated for each interconnection and allow only that vlan on the link. Then you simply transfer the IP addresses assigned to the physical ports for the SVI to the new VLAN on each switch. You should make sure that the vlan that you authorized through the link was not the vlan native because you need a tag to add.

• QoS LAN - how to say switchport reassign CoS value to mixt?

  Hi all

  There is an order issued on the switchport which tells a Cisco IP Phone trust the CoS of a station connected to the access of the phone port said, but to change the tag to a CoS value of your choice. Example:

  MSL qos trust cos

  switchport priority extend cos 3

  I have, however, is a resort with important data traffic only able to send traffic on CoS 0 and no voice/phone.

  So I want to load the switchport to assign a CoS value of 3 for traffic from the stand-alone PC station.

  Y at - it an IOS command that makes this possible without going through a Cisco IP Phone between the port and the PC Station?

  Hi Dean,

  Specifically, if the mls qos cos 3 command is ineffective for IP packets  and the port is configured to trust dscp, then how would an  administrator set the desired DSCP priority level for those packets  he/she wants?

  What you're asking here contradicts itself. Trust the DSCP means "the DSCP value is good and requires no rewriting"-why would you want to override the DSCP value, then?

  Note that even for the mls qos trust cos, the mls qos cos command applies only to those executives who no CoS present on the ground because the 802. 1 q VLAN tag is missing. If the frame has a CoS field, the mls qos cos command does not apply. With qos trust dscp mls, a similar mls qos dscp command makes no sense: each IP packet has a DSCP field in its header, and non - IP packets have no DSCP whatsoever.

  However, there is a way to actually classify and possibly rewrite the DSCP values in a more precise way by using the class- and policy-cards used in the command of the service-policy interface. This command can be used instead of mls qos trust command and perform more thorough, more elaborate classify and re-writing of DSCP value. See:

  http://www.Cisco.com/en/us/docs/switches/LAN/catalyst3560/software/release/15.0_2_se/command/reference/cli2.html#wp6193114

• Cisco SG-300 52 QoS default DSCP to queue mapping

  I am setting up QoS (Advanced mode) switch Cisco SG - 300 52.

  I decided to go with DSCP to manage the priority of the packet. While the implementation I found a configuration page (see the attachment for screenshot) where it is possible to map DSCP values in a particular queue. I did not quite understand the default settings of this mapping.

  The assignment of the queue increases from 1 to 4 for 0 to 47 DSCP values. Well, the 48-63 DSCP values were assigned #3 queue. In this way the package with value DSCP 56 will have lower priority than package with value DSCP 40. It makes no sense to me. Should not increase the priority (and thus the queue) that the increase of DSCP values?

  Why the 48-63 DSCP values were assigned #3 as default file?

  I think that the answer to this direct request found in RFC 2475

  Here is the link to the RFC.

  https://www.ietf.org/RFC/rfc2475.txt

  I think the info you're looking for are under classifiers. I deny not that under any normal logic to increment just respectively. For some reason, it was the standard/normal values agreed.

  I don't know with the first 6 bits in binary has something to do with the decimal value (expressed in a number which is not binary DSCP).  Also, I think it has to do with how the cycle increments of 8 values.

  By RFC 791, here are the priority values.

  https://www.ietf.org/RFC/RFC791.txt

  Example:

  000 = Best Effort

  001 = priority

  010 = immediate

  011 = audio/video.

  100 = flash on Ride

• Question of marking DSCP QoS VCS.

  I want to audio/video/signaling traffic values recommended in the SRND QoS of Medianet 4.0 in our VCS (video Communication Server).  The recommendations are for audio and interactive video the same signalling to CS3 and CS4.

  However, when I web in the VCS management application, there are only two drop-down boxes for QoS/DSCP marking. A box should allow to 'media' DSCP or not. The other box is to enter the DSCP value.

  I guess that the "media" are video and audio.

  Three questions:

  1. "media" means the audio and video packets?

  2. any reason why traffic is not part of the functions of the VCS - DSCP marking or is this configuration point somewhere else in the GUI?

  3. If there is no way for VCS mark signaling packets, then it to the next layer (the switch) to mark packets of signaling?

  jkeefee,

  I understand where you are coming, and feature requests already exist for VCS for the increase of the QoS configuration options, including the marking of different for audio, video and signage and interface, area and subarea specific marking as well.

  Since there are a wide range of feature requests for VCS (as with most of our products), it is always advantageous to put as much weight as possible behind each application, as applications who demand most of the customers are those who is likely to be implemented and improved first.

  I would advise, so reach out to your Cisco account manager to report your need more capabilities of QoS on the VCS, so that it can be forwarded to the VCS product management.

  Hope this helps,

• Add a Soap header custom (OSB 12 c)

  Hello

  I am a novice person and try to add a header to a soap header. I need to add this value to the custom header to be able to call external web service through business services.

  The header value must be in the following format:

  < soapenv:Header >

  " < customElement xmlns:ns = ' http://example.com/foo.xsd "> value < / customElement > .

  ....

  < / soapenv:Header >

  
  

  It must be part of the namespace.

  
  

  I tried 'Transport header' and 'Insert' components; but when I test of JDeveloper, I don't see the value of the header in the SOAP request.

  
  

  What should I do to add this element in the SOAP header in pipeline? How should I test it.

  
  

  Thank you
  

  Hello

  Add a new custom in OSB12 header is quite simple.

  As an introduction, you have 7 types of predefined context variables:

  The message variables: $header, $body, $attachment

  Incoming and outgoing variables: $inbound, $outbound

  Adjustable: $operation

  Fault variable: $fault

  As you can see there is a predefined variable called $header, and it works in the direction of incoming and outgoing. He must inject your new custom header in this context by the following variable:

  (1) If you have not yet a final XML document for your header, create an XML example (you can do this manually or if you have an xsd, you can generate an XML code example using jDeveloper).

  (2) in the request pipeline drop an assign activity configured as:

  (a) value: fn - bea: inlinedXML ("YOUR GENERATED SAMPLE XML DOCUMENT FINAL GOLD")

  (b) variable: myCustomeHeader (this is to create a new variable with the structure of the XML document that is injected)

  (3) handling is complete in the case where you used your final XML from the outset. If you need to manipulate your head you can do using replace activities such as describeded below:

  (a) drag and drop a new replacement activity

  (b) location: header

  path c): $header //$header - request

  (d) value:

  (i) add a new space of names your XML header can contain in the XQuery expression builder / namespaces and give them all the prefix

  (II) build your expression to the variable element of header you want to change. You must type the path to the element, as for example: $header/myns:authentication/myns:login/@userName

  Please let me know if it worked for you or any difficulty.

• Is it possible to access AMX element using the AMS item ID and then update the value of the AMX?

  I created a prototype - where I need to create a static Page AMX element. I have a bean that will have a method of UPDATING: the user interaction with the element AMX fires this UPDATE method, and the method will determine the value of another node AMX. The example is as follows

  <? XML version = "1.0" encoding = "UTF-8"? >

  "< amx:view xmlns: xsi ="http://www.w3.org/2001/XMLSchema-instance"xmlns:amx ="http://xmlns.oracle.com/adf/mf/amx"

  < amx:panelPage id = "pp1" >

  < amx:facet name = "header" >

  < amx:outputText value = "Header-XXX" id = "ot1" / >

  < / amx:facet >

  "< amx:selectOneChoice label = '1' id = 'soc1" value = ""valueChangeListener ="#{SolverLogic.Update1}" > "

  "< amx:selectItem label =" "id ="si667803"value ="-1"/ >"

  < amx:selectItem label = 'O1' id = 'si667804' value="667800.667803.667804"/ >

  < amx:selectItem label = "O2" id = "si667805" value="667800.667803.667805"/ >

  < amx:selectItem label = "O3" id = "si667806" value="667800.667803.667806"/ >

  < / amx:selectOneChoice >

  "< amx:selectOneChoice label ="2"id ="soc753865"value =" ">."

  "< amx:selectItem label =" "id ="si2"value ="-1"/ >"

  < amx:selectItem label = "Ø21" id = "si753866" value="667800.753865.753866"/ >

  < amx:selectItem label = "Ø22" id = "si753867" value="667800.753865.753867"/ >

  < amx:selectItem label = "O23" id = "si753868" value="667800.753865.753868"/ >

  < / amx:selectOneChoice >

  < / amx:panelPage >

  < / amx:view >

  When the user selects 'O1' - 'SolverLogic.Update1' bean - will calculate 'Ø21' must be selected. Is there a way to access the node AMX 'amx:selectOneChoice label is '2' ' - using the ID - id = "soc753865" sound, and then set the value as "value = 'Ø21' '"

  My requirement is that I don't need a DataController object, I have a binary file that contains the business logic, what I need is to create a static page and then use business logic to determine the result of user interaction and then update the user interface accordingly.

  Thank you

• Com.oracle.httpclient.HttpRequestBuilder and http header defined by the user

  Hello

  In Java ME embedded 8, I would like to send an HTTP request containing an identifier defined by the user in the (X-header type) http header, using the com.oracle.httpclient package.

  Please let me know if Miss me some configurations to pass the variable to anna64 HTTP_OAM_SAMACCOUNTNAME OAM to the Summit.
  
  Thanks for your help.

  Hi 900202,

  You can run

  begin

  end;
  

  in the SQL commands to see all headers. Maybe OAM_SAMACCOUNTNAME went without an HTTP_ prefix or its value is null, because there is a configuration problem in OAM.

• The default value for the elements of the page get ready when the session is disabled

  Hello
  
  I am facing this problem, do not know how to solve this problem. Basically, the default value 'elements' on the page don't prepare you when the session is disabled and I visit the page for the first time. So when I check the session for the first time, all page elements are null. But when I revisit the page, page elements sometimes gets.
  
  Don't know what I'm missing here... Someone has encountered this problem before?
  
  Thanks in advance! Kindly let me know if you need more clarification.

  Is there a way that the page element can be defined at the time the page is loaded for the first time?

  Yes. Create a "Page Rendering" PL/SQL process. That it is very early in the page rendering (i.e. "on charge ‑‑ after Header"). Set the value of the element of page here:

  BEGIN
