QOS Shaping vs Policing

Posted by Peter Kurdziel on June 4, 2009

The following table lists the differences between shaping and policing to help you choose the best solution.

http://www.cisco.com/en/US/tech/tk543/tk545/technologies_tech_note09186a00800a3a25.shtml

Shaping Policing
Objective Buffer and queue excess packets above the committed rates. Drop (or remark) excess packets above the committed rates. Does not buffer.*
Token Refresh Rate Incremented at the start of a time interval. (Minimum number of intervals is required.) Continuous based on formula: 1 / committed information rate
Token Values Configured in bits per second. Configured in bytes.
Configuration Options
  • shape command in the modular quality of service command-line interface (MQC) to implement class-based shaping.
  • frame-relay traffic-shape command to implement Frame Relay Traffic Shaping (FRTS).
  • traffic-shape command to implement Generic Traffic Shaping (GTS).
  • police command in the MQC to implement class-based policing.
  • rate-limit command to implement committed access rate (CAR).
Applicable on Inbound No Yes
Applicable on Outbound Yes Yes
Bursts Controls bursts by smoothing the output rate over at least eight time intervals. Uses a leaky bucket to delay traffic, which achieves a smoothing effect. Propagates bursts. Does no smoothing.
Advantages Less likely to drop excess packets since excess packets are buffered. (Buffers packets up to the length of the queue. Drops may occur if excess traffic is sustained at high rates.) Typically avoids retransmissions due to dropped packets. Controls the output rate through packet drops. Avoids delays due to queuing.
Disadvantages Can introduce delay due to queuing, particularly deep queues. Drops excess packets (when configured), throttling TCP window sizes and reducing the overall output rate of affected traffic streams. Overly aggressive burst sizes may lead to excess packet drops and throttle the overall output rate, particularly with TCP-based flows.
Optional Packet Remarking No Yes (with legacy CAR feature).

QOS: How to memorize IP Precedence Values – lol

Posted by Peter Kurdziel on June 3, 2009

From: http://cciepursuit.wordpress.com/2008/05/15/lab-tip-remembering-ip-precedence-values/

You could look this up in the DOC CD, but there’s a quick and dirty way to do this on the command line.

1) Create a class-map.
2) Type ‘match ip precedence ?’ to see the context-sensitive help.  This will give you a list of the IP Precedence values along with their descriptions.
3) Get what you need and remember to delete the class-map.

Rack13R6(config)#class-map FAKE
Rack13R6(config-cmap)#match ip precedence ?
<0-7>           Enter up to 4 precedence values separated by white-spaces
critical        Match packets with critical precedence (5)
flash           Match packets with flash precedence (3)
flash-override  Match packets with flash override precedence (4)
immediate       Match packets with immediate precedence (2)
internet        Match packets with internetwork control precedence (6)
network         Match packets with network control precedence (7)
priority        Match packets with priority precedence (1)
routine         Match packets with routine precedence (0)
Rack13R6(config-cmap)#exit
Rack13R6(config)#no class-map FAKE

qosin-10-minutes

Posted by Peter Kurdziel on April 1, 2009

I found this interesting.

http://pushkarbhatkoti.wordpress.com/category/qos-in-10-minutes/

 

A practical approach- QoS in 10 minutes (any scenario)

August 7, 2008 at 8:42 am | In 1, QoS in 10 minutes | 11 Comments
Tags: ,

Bullshit! how can anyone do the QoS part in 10 minutes?

YES its possible! and proved…. keep reading :)

I have seen many people struggling with QoS and till last minute they are not 100 percent sure that if what that is the right solution what was asked in the monster exam. Even you have a good understanding of  QoS and you say that oh yeah, I have no problem with QoS but just about the enormous time everyone is puts in configuring the QoS itself.

Everyone may have different approach to win the lab game but my approach was like this;

The whole lab has 100 points. To pass the lab we only need 80 points.
- Don’t touch LAN QoS – u hve to configure on 3 switches. CatOS is creepy, it may spike other things as well. AS u know 6608 blades are really old, applying QoS onto those older crabs may hung or may behave un-expected. I kept hearing from others that they had issues where they had to reset the 6608 blade or ethernet module. I was lucky, as here in Sydney lab I never had that kind of issue(s).

So the bottom line is, don’t be too greedy and you may safely leave some topics where you are not 100% confident (as i did). As we all know that the lab exam is not like the university exam where you’d be given points for partially correct answer.
The real benefit of leaving  non-confident topics is “Save time” and put that time in doing other things , may be you can utilize that in verifying the answers again and agin until u drain your 8 hours time.

HQ(config-fr-dlci)#
HQ(config-fr-dlci)#auto qos voip trust fr-atm

Now lets see what MAGIC has the above command has done in your router;

Common Myth: Auto-QoS breaks many things. I had the same concept until I proved that it does’t break anything and is a real time saver tool.  I know all bootcamps teaches not to use it, but they don’t explain you why not! May be they don’t want to tell you the secrets? duh! (just joking) . I never been to any bootcamp so I really don’t know what they teaches. I did everything start to finish in 9 months myself, self learning method with a few wonderful online study mates!

the other myth is wheather it is allowed in the real lab exam – yes it is, I raised this question with Ben NG on Ask Expert and his answer was “yes you can use it as long as it qualify the questions requirement” , in other word, its not just run auto-qos and thats all, you need to fine tune it.

Change#1 in existing configuration
—————————–
First lets see if anything got changed in physical interface;

HQ(config-fr-dlci)#do sh run int s0/3/0
Building configuration…

Current configuration : 196 bytes
!
interface Serial0/3/0
description — to frswitch –
no ip address
encapsulation frame-relay
ip ospf dead-interval minimal hello-multiplier 4
no fair-queue
frame-relay traffic-shaping <—- NEW NEW
end

HQ(config-fr-dlci)#

note; U don’t hve to remember to put that command if you are doing FRTS.

Change#2 in existing configuration
—————————–

Next, lets see what has changed on sub interace:

HQ(config-fr-dlci)#do sh run int s0/3/0.1
Building configuration…

Current configuration : 236 bytes
!
interface Serial0/3/0.1 point-to-point
description ====== To SITE-B =======

class AutoQoS-FR-Se0/3/0-201 <—WOW
auto qos voip trust fr-atm
end

HQ(config-fr-dlci)#

Change#3 in existing configuration
—————————–
HQ(config-fr-dlci)#do sh run | be class
class-map match-any AutoQoS-VoIP-RTP-Trust
match ip dscp ef
class-map match-any AutoQoS-VoIP-Control-Trust

!
policy-map AutoQoS-Policy-Trust
class AutoQoS-VoIP-RTP-Trust
priority percent 70
class AutoQoS-VoIP-Control-Trust
bandwidth percent 5
class class-default
fair-queue

wow – thats sound really time saver here! but what about virtual template and frame-relay class?

well u won’t get everything spoon-feed :(
but wait! shut up!

this baby feeds you everything…. ‘auto qos voiptrust fr-atm’is the man here!

Change#4 in existing configuration
—————————–

HQ(config-fr-dlci)#do sh run | be Virtual-Tem

frame-relay interface-dlci 201 ppp Virtual-Template200

frame-relay cir 512000
frame-relay bc 5120
frame-relay be 0
frame-relay mincir 512000
!
!

I think thats pretty much all you need for MLPPP scenario, for FRTS only
you need use this command:

HQ(config-subif)#interface 3/0.2 <— going to CME site for example
HQ(config-subif)#bandwidth 2048
HQ(config-subif)#
HQ(config-subif)#!now the magic part
HQ(config-subif)#
HQ(config-subif)#frame-re interface-dlci 202
HQ(config-fr-dlci)#
HQ(config-fr-dlci)#auto qos voip trust <— just that yes, noticed there is no “fr-atm”

Summary of commands;

auto qos voip trust          <—- for FRTS only , no mlppp
auto qos voip trust fr-atm   <—- for MLPPP only

How can you save time?
——————-
1. you don’t have to look in the docCD for any command.
2. Just quickly put the above template on all sites and then copy and paste them into notepad and modify according to the questions need.

Some one who’s reading this blog must be saying that “Enough of the bullsh**t and about to close firefox/IE windows and probably mumaling about ‘oh dude come on now and get to the real life, show me how to do any QoS scenario in 10 minutes”

Hue…. you are 20 yrs+ old now [no morebaby] and still expecting someone will spoon feed you the QoS tricks?
ok ok… showing you in a sec….

Lets take an example;

a. mark sip and h323 traffic to cs3 [ since I hate switches, I will do it on router itself].
b. hq to siteb = MLPPP,                  PVC = 512kbps
c. hq to sitec = frf.12/shapping    PVC = 2048 kbps
d.misc…. whatever…

Step#1: do the marking first
config t
class-map match-any NBAR
match protocol Sip
match protocol h323

Policy-map remark
class NBAR
set dscp CS3

interface fas0/0
service-policy input remark

now thats done HQ router, do show run and copy and paste it to other routers. Note when you copy and paste to other router it may take a bit of time to see the all commands pasted on the router, just paste on siteb router and move on to site c and paste there as well. Then come back to siteb router apply service-policy input on the lan facing interface and then move on to siteC router to apply the service-policy input command.

tips1# my fas0/0 had 3 sub-interface – fas0/0.10 for server ,  fas0/0.100 – hqvoice-vlan, fas0/0.1000 for datavlan. So instead of applying service policy on all 3 interface, just apply on the main one ie..e fas0/0.
wow!

tips2# I have seen most of my friends tends to be leaving data vlan at siteB for marking. So put on both data and voice vlan at siteB.

tips3# Also noticed, at siteC CME router, be careful when marking. at my home lab i had 2801 router and 2 sub-interface on fast0/0 interface e.g. fas0/0.100 = voice, fas0/0.1000 =data. So i just put my QoS service policy on fas0/0 like i did on my Hq router.

Now you all propably think that marking on router is done and wow easy 10 points. but when you read your score report u will see “ZERO”!! Damn blame the innocent  guy at http://www.ccievoice-assessor.com/ coz he graded your lab wrong! May be he was in a pub just before he got back and went straight into your pod to start grading it!!

Think about SITEC where you’ve h323 RAS traffic also needs to be marked to CS3. You probably applied the QoS service-policy on fas0/0 [in my scenario above] and when dialpeer tries eastiblishing a call to hq, h323 signaling straight hits to WAN interface.
Think about it! , you’ve applied marking on fas0/0 , when you confirm the QoS marking u won’t see that h323 protocol counters in the show policy-map interface command.
bummer!

So above practice is just to mark signaling stuffs on each routers – max time 2-3 minutes. [not for the guys who don't know where "q" key is in the keyboard]. BTW people call me sometime a stenographer coz my typing speed is like those people who type really fast without looking at the keyboard [touch typeing]

Now remaining 7 minutes and I have the whole QoS job to bind up. . damn it doen’st look right.

STEP#2 Everything else, apart from marking;   s0/3/0.1 = hq to siteb , s0/3/0.2 hq to sitec

config t
HQ(config)#int s0/3/0.1
HQ(config-subif)#
HQ(config-subif)#!first Assign the bandwidth to this interface this is a must
HQ(config-subif)#
HQ(config-subif)#bandwidth 512
HQ(config-subif)#!now the magic part
HQ(config-subif)#frame-re interface-dlci 201
HQ(config-fr-dlci)#auto qos voip trust fr-atm
exit

apply that command to siteb as well. at siteC router just use ‘auto qos voip trust’ for frf.12 or frts
STEP#3 copying/pasting and modifying parameters in notepad to/from router. MAX time = 4 minutes

Do ’show run’ pipe out the class-map+map-class+virtual-template and paste them into the notepad.
HQ(config-fr-dlci)#do sh run | be class

class-map match-any AutoQoS-VoIP-RTP-Trust
match ip dscp ef
class-map match-any AutoQoS-VoIP-Control-Trust
match ip dscp cs3
match ip dscp af31
!
!
policy-map AutoQoS-Policy-Trust <—– use this default for HQ-2-siteB
class AutoQoS-VoIP-RTP-Trust
priority percent 70
class AutoQoS-VoIP-Control-Trust
bandwidth percent 5
class class-default
fair-queue

interface Virtual-Template200 <————–WoW
bandwidth 512
ip address 10.10.33.1 255.255.255.128
ppp multilink
ppp multilink interleave
ppp multilink fragment delay 10
service-policy output AutoQoS-Policy-Trust
!

HQ(config-fr-dlci)#
HQ(config-fr-dlci)#do sh run | be map-class
map-class frame-relay AutoQoS-FR-Se0/3/0-201
frame-relay cir 512000
frame-relay bc 5120
frame-relay be 0
frame-relay mincir 512000
!

Within your notepad, copy and paste the policy-map (above) commands, we need to prepare that for hq to siteC.
policy-map AutoQoS-Policy-Trust-SITEC <—– copy and paste within notepad rename end of itSITEC
class AutoQoS-VoIP-RTP-Trust
priority percent 70 <————change them if required
class AutoQoS-VoIP-Control-Trust
bandwidth percent 5 <———-change them whatever u want
class class-default
fair-queue

another copy and paste business withing notepad;

frame-relay cir 512000 <— that shud be 95% of pvc according to the QoS SRND
frame-relay bc 5120 <——-ditto—-
frame-relay be 0
frame-relay mincir 512000 —-ditto—-

tips#?# press ctrl + h in notepad put infront of find – 5120 , replace-with 4864 (95% of pvc), and hit replace all.. bingo… ur all 3 parameters are replaced now. do the same for hq to siteC frame-relay pvc parameters.

Once everything is ready in notepad, paste above parameters back to routers. Make a note that hq and siteC frame-relay class-map name could be different and also under map-class service-policy statement u need to remove the existing one first then type the new one ’service-policy output autoqos-blah–sitec’
paste pvc parameters at the same time.

Last step4# verification

show policy-map interface and check the counters.

break-down of time is;

3 minutes = marking
3 minutes = applying autoqos
4 minutes = modifying parameter and pasting them back to router and verification.

First time when I did this practice, it used to take my 30-40 minutes. Gradually when I knew inside out where to modify and how to use notepad I really reduced it down to 10 minutes. Believe me, its doeable, just matter of the practice.

do this practice 10 times and when u reach to 11th then u will see oh, QoS is only 10 minute job.

Note, I haven’t included the time in reading the QoS question in above 10 minute business.

The other important tip is, read the question 3 times and verify that if the solution u are working on is going in the right direction.
