ASR9000 QoS
I have my first QoS policy to write for ASR9000 running MPLS VPN, and have a few questions.
The requirement is to protect router control plane traffic on the egress links (PE-PE/P) from user traffic for a throughput test. Currently, if I load up the router with simulated customer traffic from a test set not surprisingly I can get BFD etc to run into problems when the PE-P egress load approaches 100% utilisation.
I need to protect ISIS, BGP, LDP and BFD from the user traffic.
So far I understand ISIS uses CLNS so falls outside of MQC and IP QoS, this is prioritised by an internal process on the router. Do I have to do anything else to protect the ISIS traffic?
Can I mark BGP, LDP and BFD within the appropriate configuration sections in the router, or do I have to use ACL's class-maps etc to mark packets generated by the router?
I'll be plowing through the QoS guide and the documents on this forum again today, any head up info appreciated.

Hi Andy,
For routing protocols like ISIS, BGP, OSPF and LDP for MPLS you dont need to set the QoS class manually, this is done automatically. Nevertheless, in your outgoing service policy you still need to do the bandwidth allocation for that. You implement this by matching on EXP 6 and EXP 7 if you run MPLS on the interface or by matching on PREC 6 and PREC 7 on interfaces running plain IP. After matching the control traffic you allocate e.g. a minimum interface bandwidth of 1%, depending on how much control traffic you expect. Normally on Gig and 10Gig interfaces, 1% is sufficient IMHO.
For BFD, see the following document:
http://www.cisco.com/en/US/docs/routers/asr9000/software/asr9k_r4.3/routing/configuration/guide/b_routing_cg43xasr9k_chapter_011.html#ID567
In this case you need to set and match the priority bits manually on the echo packets.

ASR9000/XR - QoS - Limit overall amount of bandwidth per IP
We have a few thousand broadband customers in our network with various speed packages. The highest speed package of 500Mbps.
I'm trying to create an ingress QoS policy that I can apply on my interface facing my upstream providers that will limit put a bandwidth cap PER IP ADDRESS of 500Mbps.
I don't want to limit the overall interface to 500Mbps.
Goal of this is to protect my links deeper in my network from getting over run in the event of a DDoS attack.
Now I know this is not going to protect or mitigate any DDoS attack (like the vDDoS solution with the VSM and Arbor Networks), as budgets are not allowing me to go down that road at this time.
Any ideas on how a QoS policy would look like?
I can limit the overall interface, but struggling with how to limit an interface on a PER IP basis because i want to utilize as much of the 10GE port as possible (under normal conditions).
Simple diagram below.
Look forward to any ideas on this!

i have some question regarding the PBTS :
we can't configure more than 8 TE in the default class ,is this limitation will solved on the coming release
can i have one forwarding class assigned to 32 TE tunnels and traffic loadbalance through all of them ?,
if a default class traffic come and there is no default forwarding class TE tunnel ,does it drop or it will goes through any other TE forwarding class tunnel without been affected with dropping or QOS problem for example? .
.if any one can help it will be great .Hello,
1.
I recommend taking a look at this document
http://www.cisco.com/c/en/us/support/docs/routers/asr-9000-series-aggregation-services-routers/117718-technote-asr9000-00.html
The 1.2Tbps is the chassis limit, as newer LCs and FCs come out we will be able to utilize more of the potential bandwidth.
2.
For power supplies you need N power modules to power all the HW in a particular router.
What if a single power supply fails? In order to prevent the system from shutting down a card due to lack of power its recommended to implement N+1 power supplies
What if your A or B feed fails?
For DC you have two power connectors to each power supply so you can connect both feeds, so if feed A goes out feed B can handle the load and therefore N+1 is okay for DC.
For AC you can only use a single feed, therefore is feed A goes all power supplies connected to feed A will no longer work. So for feed-level protection you need N+N protection.
3.
Correct, the 9904 has an enhanced backplane and a higher theoretical limit than the 9010 or 9006 which have been out for considerably longer.
4.
I am not sure where the term plane comes in effect here, can you share a link to the presentation that shows this? Unicast and multicast packets all go through the same ASICs but we have different queues for these traffic types.
5.
The MGID and FGID you should never need to worry about, these are calculated automatically.

HIi,
I am trying to design a policing strategy/implementation for circuits we provide as a Service Provider, be it internet circuits or EoMPLS circuits (in the future I will have the requirement to do the same for VPLS and L3 IPVPN circuits).
All of the customer circuits come into ASR 9001's on bundle-ethernet interfaces and I am looking to police on the subinterface (or whatever anyone else can suggest as a better solution, what do other SP's do to throttle customer circuits to the CIR/CDR?).
I have tried to do some tersting using the below policy-map:
policy-map 10mbps-POLICY
class class-default
police rate 10485760 bps burst 104858 bytes peak-burst 209716 bytes
conform-action transmit
exceed-action drop
end-policy-map
After applying this to a subinterface in the inbound direction I run speedtests (to multiple different servers) and I get around 8.5 - 9 mbps most of the time, on a couple of occasions I got 10 mbps
After applying this same policy-map to the same subinterface in the outbound direction I run speedtests (to multiple different servers) and I get between 20 and 21 mbps.
Can someone please help to explain why this is happening and if this is the right approach?
Thanks a lot in advance.There are 2 possible explanations for this:
First of all it is important to understand that when you have bundles, the qos policy or features are individually applied to all members. So with 2 members in a bundle, and assuming perfect loadbalancing you could see twice the assigned BW applied. That because each member is policed at the rate defined.
When the policer is not reaching its defined rate, that generally is caused by the burst setting size of the policer. If you have a 2 rate 2 color policer which is what you have here, then either the traffic conforms or it doesnt. and if it doesnt it is dropped. this gives you a very sawtooth like behavior.
It is generally nicer, maybe, to set up for a 3 color policer with confirm, exceed and violate.
Allow packets within the rate to be marked green and burst traffic marked yellow and still transmit where the violate action will indeed be drop.
Have a look at the asr9000 quality of service architecture guide on the forums with some details on the policer and config. Also the cisco live 2904 from 2013 and 2014 have some additional details on the QOS archi that you may like.
As for the bundle doubling the bw etc, there are few options, vlan or destination based loadbalancing or reducing the BW to configure "half" of what you want to assign when you have 2 members so that the total agg is the desired bw.
This percentage based approach is nice also in case a member disappears so all services degrade equally by ratio properly.

QOS guide or samples for EHWIC-4ESG-P
I'm looking to configure QOS on a EHWIC-4ESG-P however there isn't much I can find for configuration guide on doing that. Does anyone have a good document on that or an example config ? I'm looking to match COS on the switchports, map COS to DSCP, and continue on from there. Any help would be appreciated..

hi,
Got a question,
ASR9k has 2 system HP queue and a default queue, there is no dokument i can find that descripe how packets are mapped into this system level queues per default, from packet enter the ingress interface util the packet leave the egress interface.
If you configure the priority-level at the egress direction as output policy, will the packet matched be tagged with this same system level priority from ingress port already? The reason is that from bridge FPGA towards NP there is only 15Gbps full duplex bandwdith, if traffic are not tagged with hp from the ingress already, it will be dropped when traffic over 15 Gbps.
Cheers
GuanHi Guan,
I recognized the lack of documentation to that topic and for that purpose I created a technote on A9k QOS

Question Regarding QoS and Firewalls Rules
Hello experts, I hope a simple question for you today. I am working to elevate our outdated H323 traffic down a VPN tunnel we are only getting 600k throughput on.
Under "Networking --> QOS --> WAN QOS" I have configured the downstream and upstream bandwidth rates using the 85% rule. I have also created a bandwidth profile called VOIP using 128-256kbps with a priority of "High"
Under "Traffic Selector" I have created the profile using the VLAN 100 for the IP phones with the VOIP bandwidth profile.
My question, is this the correct configuration and I'm done? Or do I need to go further and create the same IPv4 rules in the firewall rules giving it a QoS Priority of "Minimize Delay"
Is there a way in SA540 to see the QOS statistics to see if they are working correctly? I appreciate your input as always experts!!It's about the relevance of the link. Some will post a vague link to the SAP help that adds no value to anyone trying to find the answer to the question, whereas a targeted link to a - possibly difficult to find - page can be very useful.
It's a bit of a subjective thing, example:
A detailed question asks about technical info behind assigning a cost center to an organizational unit in the org chart.
A reply such as:
Check [this link|http://help.sap.com/saphelp_erp60_sp/helpdata/en/0b/dfba3692dc635ce10000009b38f839/frameset.htm].
Is just wasting everyone's time. Unfortunately we see a lot of these, people seem to think it's a quick way of getting cheap points but it just frustrates everyone else.
Asimilar answer can however be very useful if it contains a targeted link that relates directly to the question, e.g.
See the help on [account assignment infotypes|http://help.sap.com/saphelp_erp60_sp/helpdata/en/bb/bdb2b6575911d189240000e8323d3a/frameset.htm].
However a generic link as per my first example as part of a detailed explanation with a comment of "further info can be found over here" is a good post since the purpose of the link it more for convenience or reference info in addition to the answer in the post.
Hope that helps,

Cisco Jabber Client - QoS Config
Hi Guys,
I'll be deploying the new jabber client for a customer and i'm unsure of what QoS to configure on the switch ports for end users. Users will also have 7942 handsets, so if i configure auto qos voip cisco-phone, I doubt this will protect the voice/video for Jabber.
Has anyone got any config or tips they can share?
Cheers,
JamesHi,
I believe you can use "auto qos voip cisco-softphone"

Cisco 7206 has with LLQ QOS and cpu 85 %
hi all ,
i want to mention issue about cisco router 7206 npeg2 :
can this router handle traffic 780 Mbps as download and 75 MBps as upload ?? with cpu 85 % and with LLQ qos ??
im asking this question because my QOS althoug it matched alot of traffic , it some time get slow and seems that QOS not working fine , im sure that my work is fine, because it was fine , but recent days i added more bw ???!!!!!
dont know if need more memory for router for QOS :

I already mention the TurboACL feature statement. With ACLs, fewer are faster, and how they ordered (especially without TurboACL) impacts CPU. How you order you class-maps, within a policy, and how the match statements are ordered will also have some impact on the CPU load. If buffers are being allocated/deallocated, that too will impact CPU loading. I assume CEF is enabled, but for some traffic, flow caching might decrease CPU load.Remember a software based router, like the 7200s, are, more or less, a computer that takes your configuration and determines what's to be done with every packet it "sees". The more your configuration requires for per packet analysis, the more load for each packet.There are whitepapers addressing high CPU load caused by "process switching", but what you posted appears to be mostly all interrupt processing, which is "fast path", or optimal, packet forwarding. There's not much you can normally do to improve against that, other than insuring your configuration is as optimal as possible for your needs (again, things like sequencing/ordering of statements).
hi ,
thanks very very much for this nice information,
let me answer you :
you said that NPE G2 has finite capacity , but how to know this full capacity ???
i mean that my policy map is matching the traffic , but the matched traffic is not being enhancemend ??!!!
last about two weeks , the matched traffic of youtube was excellent and no interrupt durting the my rush hour.
i didnt change any thing, but my bw increased from 730 Mbps to 760Mbps ,
im un able to make sure that i need to chnage my platform to faster one.
agian
my cpu is 60 % without QOS
after QOS it increase to 80-85 %
agian ,
about NBAR
i want to tell you that i cant depend on NBAR , as an example , im matching the ips of videos of facebook , i cant depend on NBAR because it is https videos.
but in summary ,
my qos is matching well , but i have no real enhancement for my traffic.
did you face my issue before ???
i mean have you see like my problem ?
like my router platform with cpu over 80 % and 750Mbps , and matched qos without good result ??
note that i upgraded to iso 15 , but seems same issue !!!

How to apply Qos in the precedence of cache server
m in an isp and iwant to apply the QOS to enhance my network internet performance
actually i have two requests , i will start with showing brief topology about my network and start asking the questions .
here is the topology below :
from the topology above , my access is only on R1 which is BGP internet gateway router and R2 is my ISP router.
1- i want to apply Qos on R1 so that a subnet of 32 ips to have gurantee bandwidth of 30M .
assume the subnet is 10.20.30.0/27 that need to be bw gurantee .
2- i want the download traffic by idman or ftp on my Router R1 dont exceed 50 % of my total bw .
i mean that i have 450M bandwith from my isp , & sometimes we have a slow in browsing , so i want to enhance the browsing quality because its more important that downloading files from internet.
here is my two requests above , i dont know how it will work with the precedence of the cache server .
anyway , i will paste my config of router and i will replace my puplic ips with xxx for privacy .

How to change default FCoE QoS class - Nexus 5020
I see that on a Nexus 5020, the default FCoE QoS class is 50%. I am not using FCoE so I would like to adjust this value to 0%. I switch complains and says I can't change default values. How should I go about getting around this to eliminate the FCoE queue and give 100% BW to default? Thanks.
No. The default classloader is a builtin classloader in
the JRE. You can use other classloaders.
The java.net.URLClassLoader is provided in
the JDK. That's the only one. Otherwise you
should subclass ClassLoader and implement
the loadClass method (f.i.
loadClass("my.program") {
String file="my.program".replace('.','/') + ".class";
// find the file in classpath
// read the class file in a byte[]
return defineClass(byte[]);
although this is not the advised way to do it. Search the web for how to implement a classloader directly. -
VoIP QoS for Site-to-Site Tunnel
Hi all,
I need some help with setting up QoS for VoIP between two Cisco ASA 5505 with Site-to-Site VPN.
There is no need for bandwith reservation, only DSCP 46 (EF) should be highest and DSCP 26 second highest queue and the rules should only apply to a site-to-site VPN.
Usually i try to configure the ASAs via ASDM and found out in the Cisco Documentations how to setup QoS for the DSCP bits with a Service Policy and how to set up QoS for a Site-to-Site VPN (Service Policy Rule -> Traffic Match). But how do i configure the QoS for a DSCP bit to only apply to a Site-to-Site Tunnel? And how do i configure different priorities for the two DSCP bits, is this defined by the order of Service Policies?
The QoS has to be enabled on both ASAs for the inside interface?
Thanks in advance
TobiasHi Collin,
ok so from the document i think this has to be added on both ASAs to prioritize DSCP 46. Could you have a quick look if this is all i need?
class-map voice_traffic
match dscp ef
class-map data
match tunnel-group <Tunnel Name>
match flow ip destination-address
policy-map voice_policy
class voice_traffic
priority
class Data
police output 200000 37500
service-policy voice_policy interface outside
But there is still the question how two configure another DSCP bit for priority 2, I could not find out how this is done, neither CLI nor ASDM. Any ideas?
BR

Problem with QOS for SIP on RV082
Hello,
I have problem with quality of VOIP call with Linskys RV082. Firmware is 2.0.0.19tm.
Router is configured as dual-wan , one port (WAN2) is for ADSL 8000/512kb and other one is (WAN1) SHDSL 8000/8000kb.
VOIP traffic from certain IP of LAN is routed to WAN2 (through protocol binding). We have quaranted QOS on ADSL by ISP.
Problem is that voice is dropping when we load WAN2 with other data connection. Last week i reload new firmware, restore default factory and configured router whole again. All was ok only for 1 day and then voice was dropping again. I mean that problem is at mark packets, because when I put VOIP PBX in front of behind router , QOS is working fine.
Can you help me? Is this know issue?
Thanks.

so does the command look like, the one I should use instead of priority-queue outside_wan ?? -
Is there ANY way to get QOS with an airport extreme base station?
I recently moved and decided to go with Primus VOIP for my phone line. It works fine as long as i don't have any torrents going...if i do then call quality goes to **** (i wish someone would've told me before)
I was told to use a QOS on teh VOIP ports...but my airport extreme doesn't support this (and apparently neither will the new one). Honestly this is something Apple REALLY needs to fix. This is outrageous. They're supposed to be on teh cutting edge of technology, and their routers don't even won't properply with VOIP services??? That's ********.
Is there any way i could get this to work - perhaps thru software?
It seems the only solution i have is to get a Linksys router and sell off the airportSorry that this may not seem like an ideal solution, but one option is to use an application that runs on a Windows PC that allows you to format HDDs for HFS+. Once formatted as such, it can be shared out to either OS X, Windows, or Linux users from an AirPort Extreme or Time Capsule. HFS+, like NTFS, supports much larger HDDs.

How to configure QOS on certain IP in the Cisco ASA 5510
Hi,
I am need to configure QOS on certain IP in the Cisco ASA 5510. Assume the IP's are 10.0.1.5 , 10.0.1.6 , 10.0.1.7. Here i have to configure 512 KBPS for 10.0.1.5 and 2 MBPS for 10.0.1.6 and 10.0.1.7
Can this done on a ASA 5510 series? if yes can you help me how ?
Regards,
VenkatYes you can do it.You can match the ip addresses in an access-list, put in a class-map and the class-map in a policy map that will do policing.
Good examples for what you want to do are here https://supportforums.cisco.com/docs/DOC-1230
I hope it helps.
