QoS Capabilities in MPLS 2

Hi:
Based on paper titled "L3 MPLS VPN Enterprise Consumer Guide" page 16 (http://www.cisco.com/en/US/partner/netsol/ns465/networking_solutions_white_papers_list.html). My SP has only 3 CoS for its VPN service. I have classified up to 10 different classes on my sites using a BW Manager device. I need to carry my CoS (based on DSCP or other way) through the MPLS VPN transparently.
1) Is it possible to map my CoS values to the CoS values used by the SP so that they can be mapped back to my network at the opposite end of the VPN?
2) If yes, How? Who would it be responsible to do that? Please explain.

Hello,
As a MPLS SP I would not like to deal with customer DSCP values in any place in my PE routers except the input interface from a pure operational point of view.
So SPs offering QoS will either remark on ingress OR transparently transport DSCP values of the customer across the MPLS domain. For transparent DSCP transport MPLS exp bits are set along with the SP policy and service purchased on the ingress interface. The trick on the egress interface, where a pure IP packet needs to be handled, is to map incoming MPLS exp (in the VPN label) to a qos group and use the qos group in the egress class-map for traffic classification. This way a SP does not need to mess with customer DSCP values.
But this is technology ... your specific SP product and technical implementation might differ, f.e. because he has other vendor PEs not able to offer those features.
Hope this helps! Please rate all posts.

QoS Capabilities in MPLS - 1

Hi:
Based on paper titled "L3 MPLS VPN Enterprise Consumer Guide" page 16 (http://www.cisco.com/en/US/partner/netsol/ns465/networking_solutions_white_papers_list.html). My SP has only 3 CoS for its VPN service. I have classified up to 10 different classes on my sites using a BW Manager device.
1) Is it possible to send CoS values to the SP cloud to be preserved until they reach the remote CE?
2) If yes, how? Please explain.

1. It is possible for your markings to be preserved since the provider will be using the MPLS EXP bits in order to provide appropriate service levels to your traffic. However, you need to verify that with your provider. There is a possibility that the provider re-marks the DSCP bits on egress. The important thing to understand here is what the provider expects to see from you in order to assign your traffic to the 3 different CoS it has. That is, you have to make sure that you purchase appropriate amounts of bandwidth for each required CoS from the provider. The provider will most likely police and mark your traffic at the PE. For example, the provider may have a gold CoS with which it associates all DSCP EF traffic. You have to then mark your traffic accordingly. Since your provider has 3 classes of service, you may have to aggregate your 10 classes into 3 that fit in with your provider model.
2. See above. Just because your DSCP markings are preserved does not mean that the provider will honour them within their core.
Hope that helps - pls rate the post if it does.

ASR 9001 QoS Capabilities

Hello,
As I understood, ASR 9001 has integrated 4 onboard 10 GB interfaces and two Line Card slots. It has MOD 80 architecture.
Onboard 10 Gb interfaces has same QoS capabilities as MOD TR modular line cards. ( 8 queues per port and etc)
What about the two Line Card Slots? If I use A9K-MPA-20x1GE, A9K-MPA-2x10GE or A9K-MPA-4x10GE line card , which QoS specifications I will have? Like MOD SE or MOD TR? As I know, these line cards has SE functions on the ASR 9001/9001S. Does it mean more than 8 queues per port? Can I terminate Pseudowire Headend on these interfaces and use QoS on them?
Regards,
Guner

Noup, the ingress / egress counters keep in 0, some times ARP complete sometimes it dont.
The router crash traing to do an OIR.

Apply QoS policies to MPLS interfaces

Hello all,
We are deploying an MPLS transport network for our research project, and we are getting undefined errors about the QoS application over tunnel interfaces. The tunnel interfaces are those we configure between end points.
For example, if we apply a rate-limit to a tunnel interface, this is not applied, although the router anc CLI let configure the policy.
Does anybody know how to manage this kind of policies or shaping to MPLS?
Thanks for your help.

Hello,
No, in fact, what we want to configure is output policies. For example, at the ingress LER of the MPLS cloud, we receive some traffic that we set it as an specific class of service, for example, "interactive traffic". Once the traffic is classified, we route it to the correct output tunnel interface, i.e., to the next LSR. It's at that interface where we want to set the policy, so.
When we set the policy, with the "service-policy output tunnel0", for example, the CLI doesn't return any message of error. In fact, it lets to configure it, and if we use the command "show policy-map interface tunnel0", CLI returns the configuration of the policy at that interface.
Thanks for your help.

QoS for Live Communication Server/Video on LAN, WAN

Hi,
Imagine I need to deploy "Microsoft live communication server" or other type of video conferencing application on LAN and WAN throughout my organization.
What type of QoS mechanism should I approach? CBWFQ? How about LLQ?

Hi,
have a look at "IP Videoconferencing Solution Reference Network Design (SRND)"
http://www.cisco.com/application/pdf/en/us/guest/netsol/ns280/c649/ccmigration_09186a00800d67f6.pdf
It covers among other things QoS in the WAN and in the Campus (LAN).
In the WAN LLQ would be advisable, LAN QoS depends strongly on your swtches QoS capabilities.
Hope this helps! Please use the rating system.

VOIP MPLS network only 40-50% utilized

We are in the process of upgrading our bandwidth at our branch locations into 3 Mbps MPLS networ and we only run Citrix traffic and IP Voice (Interoffice calls) from our Branch locations into our HQ.
We expect Bandwith utilization to typically max out at 1.6 MBPS. Do you think we need to configure QoS for the voice traffic since the circuit will only be 40-50 percent utilized? My thinking was why should I configure QoS if the bandwidth is only at 40 - 50 percent. The voice traffic should have enough bandwidth to communicate over the wire.
Is my thinking correct or should I configure QoS across this MPLS network? If I should confiure QoS what type do you recommend.
Any responses are greatly appreciated

Hi,
I would configure QoS, because there are not only sunny days in life ...
What if you catch Nimda version 7.2beta, i.e. the newest worm out there trying to blast any valid IP in your network? I would not want to explain to my CEO why we lost telephony as well ...
So on a more technical level: QoS is needed to do resource management. As such you are right in that QoS is not needed if you have enough resources. Yet, who can guarantee this in an IP network at any point in time? I would put it QoS just as an insurance though it would not be needed during normal operation.
Saying this I might add that this is the appropriate usage anyhow, as QoS will not solve issues arising from constant lack of bandwidth. Queueing is meant to handle exceptions. There is always the possibility of the unforseen.

Prioritization within QoS queue possible?

Our company runs QoS over an MPLS WAN, but I am personally new to the technology. Given that our provider only allows four queues (EF, AF31, AF21, and BE), we have configured four corresponding policies. This seems somewhat limiting, given the number of queues Cisco actually supports. Here's the question; Is it possible to further prioritize traffic within a given queue?
Say for example, we want to place a certain traffic type within AF31, but we do not want to adversely impact other traffic within the queue. By the same token, we do not want to move either of these traffic types to EF. Can we control, in a more granular manner, prioritization within a respective queue? Any clarification you can provide would be greatly appreciated.

As Laurent also describes, it's usually possible to fully manage congestion to MPLS (generally easy if you control the CE router). With MPLS, though, where the limitations of the provider's QoS model are most troublesome is upon MPLS cloud egress. It's possible to indirectly control this if you logically manage your MPLS cloud as you might with frame-relay or ATM. Unfortuanately, this is often impractical if you have more than a few nodes and have a logical mesh topology vs. hub and spoke.
PS:
Some MPLS providers allow you to select from various "profiles" of QoS model choices. This can be very helpful if traffic ratios vary between sites. Also, some MPLS vendor QoS models also provide support for different drop thresholds within some classes.

QOS from Central side to Remote end

I am wanting to apply QOS onto some of our WAN circuits. Here is my scenario. Headquarters end has a 45Mb DS3 to the MPLS cloud. Remote end has a multilink T1 (3Mb) connection to the MPLS cloud. We are doing BGP to the cloud itself. My problem is, the remote links request data from the Headquarters end (which works fine going from remote to HQ). However, when the download/file transfer starts, it completely saturates the 3Mb connection and nobody else can do anything on that circuit. I have applied some policing on the HQ end, but I also have a few hundred remote sites connecting to this cloud with the same AS number which causes some issues. Does anyone know of a way to QOS or prioritize mission critical traffic in this manner?
Please any help with this matter would be appreciated.
Thanks,

Normally, there are two things that normally can be done; BTW they are not mutually exclusive.
If your device supports CBWFQ, you could define a class per branch and shape for the branch's egress bandwidth. However, if you have several hundred branches, you may run out of policy classes.
The other approach is to use vendor QoS. Many MPLS vendors will offer some kind of QoS support although sometimes it's an extra cost option.

Any one ever worked on 6500 series Cisco switches QOS or 6503 or 6524 QOS(Urgent help needed)

Hi All,
I am having issue specifally doing QOS configuration on 6503 or 6524 or 6509 switches. I am unable to match any EF(voice) traffic for eompls(vlan based) on 6503 cisco switch. If i use any other router as 2811 or 2821 my QOS configuration works perfect but if i put 6503 as PE2 it does not work.i am using vlan based eompls.
Below is the scenario & configuration which i am having issue.
CE1(2821 router)(dot1Q)--------->PE1(2821 router)------->P(6524 switch)-------->PE2(6503 switch)------->(dot1Q)(2821 switch)CE2.
On CE1 i can match ip-precedence 5 traffic and mark that traffic to cos5 on outbound port.On PE1 i can match cos5 packet and mark with mpls exp top5 on inbound port, on outbound port i can match mpls exp 5.
On PE2(6503) i am unable to match that mpls exp5 packet on inbound port. none of the configuration worked on 6500 series switches with mls qos, ,mls qos trust dscp,mls qos trust cos etc. Although i can match cos5 traffic on CE2 on inbound interface.i can not match mpls exp 5 traffic on 6503 and all i can see traffic as default-class on 6503 switch. I tried many things and many configurations on 6503 but nothing worked.If i put 2821 router as PE2 instead of 6503 my qos configuration works. but why if i put 6503 my same qos configuration does not work?
---match means=classification or classify
Can anyone tell me how qos works on 6500 series switches or where i am having issue in my scenario.
i am using this ios on 6503: s72033-advipservicesk9_wan-mz.122-33.SXI3.bin.
below r my questions for 6503 qos:
1.do i need to use some other map tables,am i using correct map tables on 6503 as cos-dscp,dscp-cos,exp-dscp etc.
2.any other configutaion of qos needed on 6503?
3.i am unable to match anything on outbound port of 6503.
4.on 6503 i am using sup720 and PFC3BXL.any specific configuration needed for PFC3bxl.
5. 6503 not allowing me to match qos-group on inbound interface, not allowing me to set cos5 on outbound interface. not allowing me to set cos5 as an inbound interface.

IP Precedence vs DSCP in MPLS VPN

Hi there,
From my reading through Cisco website, I noticed that most of implementation suggested to use DSCP values and sometimes use IP Precedence in CE/PE class-map for classfication and markings.
What is the most appropriate or maybe best practise to configure by using IP Precedence or DSCP? Is there any difference in terms of providing QoS especially in MPLS VPN enviroment?
Thanks.
maher

Hi Maher,
DiffServ offers you the advantage of a 6-bit field so that you can offer much more granular QoS. IP Precedence only offers you 3 bits so that the QoS offered is fairly coarse. These days, most implementations would be using DSCP for that reason.
Within an MPLS core, the QoS setting is carried within the EXP field, which is a 3-bit field. Therefore, even if you use 6-bits for DSCP at the edge, you will end up having to map those 6-bits into 3-bits for carriage across the MPLS network. That is not a problem, however. You are bound to get more congestion at the edges so you need more granular QoS markings there. The core of a network is unlikely to be congested so 3 bits of QoS marking is sufficient.
Hope that helps - pls rate the post if it does.

WS-C2960-24PC-L VS. WS-C2960-24PC-S : capabilities.

Good afternoon
We are presently looking to standardize out infrastructure to use Cisco Catalyst switches, exclusively.
We presently have 1 3560, and a WS-C2960-24PC-L. These switches feed a stack of netgear switches (which we want to get rid of).
Our reason for doing so, is to bring Avaya POE IP Phones into the company to replace the digital hand sets (which are not POE).
We currently have 8 Avaya POE phones, which are all patched into the WS-C2960-24PC-L (for POE and Voice VLAN propagation).
I have found a good deal on a set of WS-C2960-24PC-S switches, but am concerned about the LAN Base model versus the LAN Lite Model.
The network setup is simple: two VLANs (data, voice), three /24 networks (routed by the 3560, directly connected).
Is there any difference, between the two models, that would prevent me from achieving my desired outcome?
Thanks in advance.

WS-C2960-24PC-L means the hardware runs on LAN Base software. WS-C2960-24PC-S means it's running a cut-down version of the LAN Base software called LAN LITE (aka LAN Cr@p). You really, really don't want to invest in the latter.
Cisco Catalyst 2960 LAN Base switches have several advantages:
• Gigabit Ethernet connectivity in 8-, 24-, and 48-port configurations
• RPS support and support for a wide range of SFP transceivers
• Enhanced security through Layer 2-4 access control lists (ACLs), DHCP Snooping, and more extensive Network Admission Control capabilities such as Web authentication and 802.1x enhancements
• Additional QoS capabilities: The LAN Base IOS supports policing, class and policy maps, differentiated services code point (DSCP), AutoQoS, and configurable queue weights, buffers, and thresholds
• Higher network-level availability with features such as Flex Links and Link State Tracking
•Increased number of VLANs (256) and other enhancements such as IPv6 Host, MLD Snooping, LLDP-MED, RSPAN, MVR, DHCP Option 82, and IP SLA (responder)

Wan Aggregation switch

Hi All,
I'm trying to select the best switch to terminate a number of WAN connections in our data centre.
We currently have a mixture of 1Gbps point-to-point Ethernet circuits, MPLS circuits and private DSL circuits coming into our primary data centre. These are all currently terminating on our core switches and I want to move these to a dedicated layer.
All I need to support is full EIGRP and multicast routing. Advanced QoS capabilities are not a must at the moment.
I'm considering the Cisco 3750 Metro Ethernet switch but I was wondering if there are any newer or better devices that are suitable for this? Also I can only see the 3750 Metro with 10/100 Mbps port. Is it available with 1Gbps ports?
Any assistance is greatly appreciated

Thank you for the quick response.
I will checkout the ME3800X.
I have also just been looking at the 3750X and 3650 range switches as well. Will these work ok or any concerns for this type of role?

Penultimate labels

It seems to me now that pop labels are only sent for directly connected network prefixes, and not for other learnt prefixes but outside the mpls cloud. For these other prefixes, the edge LSR uses the untagged label.
Is there a way to configure, such that pop labels are sent for all prefixes outside the MPLS cloud?
Does the default route always have the implicit-null label?
Also, what is the difference in the implicit-null and explicit-null labels?

Prefixes outside the MPLS domain will usually be outside your AS and therefore learnt via BGP. Inside your MPLS domain these prefixes are resolvable via the BGP next hop, which is a FEC belonging to one of your edge LSRs.
From the edge LSR you can force the propagation of an explicit-null label (label value of 0) by configuring the "mpls ldp explicit-null" command. By default LDP uses implicit-null labels for all attached FECs.
The implicit-null (label value of 3) means that the top label has to be removed (popped) before the packet is forwarded to the next-hop. In non l3vpn or l2vpn scenarios, this will leave your packet without labels and the edge LSR will base its QOS decision on the IP precedence rather than the experimental bits.
The explicit-null means that the top label will be replaced by an explicit-label value of zero. This is used in some QOS scenarios, where mpls experimental bits have to be used rather than IP precedence. For more information on when it might be wishable to use an explicit-null label, refer to the following document:

Shared execution context support in SOA Suite Products

Context:
An enterprise application is likely to be made up of components that span across the BPEL, JEE (servlets and EJBs) and ESB containers with heterogeneous mix of technologies/computing languages (especially if part of that application is a legacy application), communication protocols, transport, QoS capabilities etc. The latter opens up a complex set of related issues such as assertion, ownership and enforcement of policies and contracts (both infrastructure-oriented such as security, privacy, manageability and business-oriented such as hours of business, goods return policies) that must be managed in order for the application to behave consistently end to end. In a way, this concept is similar to one of header vs payload distinction.
Goal:
Yet those heterogeneous resources and technologies mentioned above should be abstracted (or externalized) from the business intent, ie the actual data and associated functional processing that deliver real benefits to business, as contextual information that may be both out-of-band and in-band (ie something that is created during the course of an interaction). In this way, the business components (BPEL scripts, presentation tier actions [as opposed to controllers], POJOs, or ESB mediation services implemented using XSLT scripts etc) can be reused in completely new unplanned scenarios with newer execution platforms/infrastructure since the latter can be made virtualized from the point of view of the business components.
To achieve the above, one of the key enabling factors is a shared execution context to capture such dynamic relationships between the application modules or components or services that is technology neutral but can be passed from one containers to the other seamlessly.
Problem:
Having understood the context and goals, the big question is what is the level of support for a shared context implementation found in Oracle BPEL, JEE and ESB containers? Especially in the ESB container since it is the execution environment of all services.
This overarching problem may be decomposed to the following:
* How far is loose coupling of services implemented? Strictly pure XML over HTTP or web services between tiers/containers?
* If it is pure web services everywhere, what about the impedance mismatch problem between POJOs and XML?
* If so, what is the form of a message dispatch/invocation framework to be put in place between tiers/containers? WSIF/AXIS? The choice will obviously be influenced by NFRs and to some extent the ease of integration of such frameworks with Oracle products runtime libraries.
* How does a service lookup another, at design-time or run-time?
* What mechanisms are there in each of the 3 containers above to allow for dynamic service assembly and dependencies injections?
* How should a message be structured (header vs payload)?
* How easy is the header or context that is most likely to be expressed in XML format be mapped to a run-time artifact in each of the containers? Is this mapping process lossless? This header is more than likely to carry a diverse range of information such as session and authentication tokens, management data, logs, audit trails, errors/exceptions and other QoS data.
In attempting to design and implement the above architectural requirements on Oracle SOA suite, I am unable to find any semblance of a design or runtime construct or artifact that is remotely close to what I would call a shared context. Should I conclude therefore that I would have to build the above facilities from ground up, instead of being able to customize a shared context construct or feature in Oracle SOA suite (the ESB container in particular)? I would have thought this is a fundamental capability of an integration platform such as Oracle SOA suite, am I right?

I supposed to make my previous question more concrete, the first answer I need before moving on to the rest of the bigger questions is this ...
What is Oracle’s recommendation for a services invocation framework between BPEL, JEE and ESB containers? From a quick read of Oracle Technet website, WSIF seem to be the preferred framework for this purpose. However, from an equally quick survey of such frameworks in use today outside of Oracle, WSIF does not seem to enjoy any widespread developer community support anymore and all talk in public forum seem to point to newer Apache Frameworks such as CXF which support emerging standards such as JAX-WS 2.0 What is the current stand of Oracle with respect to this matter?

Equipment needed for a proper CCIE Collaboration Lab

Currently at home I have a 1760 router, a 3550 switch a 5505 firewall, a Fortinet 60B, two Dell poweredge servers with ESXi, a DD-WRT router with QoS capabilities, and a dozen or so Cisco 7912 phones.
I'm going to be picking up a 2821 router and a POE 3560 switch in the next few days. I have access to loads of WIC cards, PVDM2's and a CUE-NM module. I also have all of the software (CallManager 9.1, Unity, UCCX, Presence, and MeetingPlace 8.6). Cisco doesnt offer a temporary license for UCCX or MeetingPlace. So I dont know if I'll be able to install it. Anybody have any idea's for that?
What else should I put on my wish list to buy? I dont have tons of money. So the newer routers and switches are out of the question. I know they expect you to have a 2900 router, a 3900 router, and a newer 4400-x switch. But realistically, what would you be able to do on those that you couldnt on a 2800 and 3560?
I do think I'll need to break down and buy a pair of video phones. I dont think there is a way around that.

Hi,
take a look at this:
https://learningnetwork.cisco.com/docs/DOC-20807 (requires login).
I don't know yet (I guess nobody does) why they changed the hw from 28xx to 29xx, PVDM2 to PVDM3.
About the switches, I guess if you've got a 3560, that would do, I can't imagine why would anyone need a newer version, unless there's something really, really specific.
UCCX license comes on the installation media (a temporary one, valid for a month, but come on, talk to your Cisco contact to generate one for you).
