Router Dead , when i applied QOS on virtual-temp interface for vpn !!

hi all ,

i have a simple brief topology below :

PSTN======(R1-7206)>F1=======F2>(R2-7604 catalyst)>>>F1=========Internet

i have two router

R2========>MLS 7604

R1======>cisco 7204

on R2 , Im doing matching to QOS by dscp , im matching acls ips from internet with dscp values :

here is CONFIG for matching :

Gateway7600#sh policy-map LLQX

  Policy Map LLQX

    Class YOUTUBE

      set ip dscp af43

    Class FACEBOOKVIDEOS

      set ip dscp af33

    Class HTTP

      set dscp af23

    Class DNSQOS

      set dscp af13

    Class class-default

      set ip dscp af11

================

Gateway7600#sh class-map

Class Map match-all FACEBOOKVIDEOS (id 7)

   Match access-group name  facebookvideos

Class Map match-all DNSQOS (id 8)

   Match access-group name  dnsqos

Class Map match-all HTTP (id 6)

   Match access-group name  browsing

Class Map match-any class-default (id 0)

   Match any 

Class Map match-all YOUTUBE (id 5)

   Match access-group name  youtube

Gateway7600#

=========================================================

on this router i applied this policy map  on interfaxce F1 in  direction

and here matching is well :

Gateway7600#sh policy-map  interface gigabitEthernet 1/5 in    

GigabitEthernet1/5

  Service-policy input: LLQX

    class-map: rate-limit (match-all)

      Match: access-group name rate-limit

      Earl in slot 1 :

        139044930 bytes

        aggregate-forwarded 134420937 bytes action: transmit

        exceeded 4623993 bytes action: drop

        aggregate-forward 22544 bps exceed 0 bps

      set dscp 14:

      Earl in slot 1 :

=================================================================================

now the problem is below

on router 7200 , it is LNS router connected with LAC roiuter for ADSL customers.

now here is config of policy map on 7200 router:

R11#sh policy-map

  Policy Map MATCH_MARKS

    Class MATCH_YOUTUBE

      bandwidth 220000 (kbps)

    Class MATCH_FACEBOOKVIDEOS

      bandwidth 20000 (kbps)

    Class MATCH_HTTP

      bandwidth 100000 (kbps)

=========================================================

R1#sh class-map

Class Map match-all MATCH_FACEBOOKVIDEOS (id 2)

   Match ip  dscp af33 (30)

Class Map match-all MATCH_HTTP (id 3)

   Match ip  dscp af23 (22)

Class Map match-any class-default (id 0)

   Match any

Class Map match-all MATCH_YOUTUBE (id 1)

   Match ip  dscp af43 (38)

==========================================================

here is virtual-template interface before i apply the QOS

R1#sh running-config interface virtual-template 1

Building configuration...

Current configuration : 352 bytes

!

interface Virtual-Template1

bandwidth 1000000

end

=========================================

when i apply the command

(service-poliy output MATCH_MAKRS ) under virtual-template  interface i have console logs :

Try removing "max-reserved-bandwidth 90", under your "interface Virtual-Template1".

Router Dead , when i applied QOS on virtual-temp interface for v

Hi ,

Mr JOSEPH ,

thanks alot for reply and intersting

1st of all ,

it failed before and after i put the bandwidth command

and

max-reserved-bandwidth 90 command

========================================================================

after alot of investigation in the issue ,

i found that i cant apply qos under the virtual template interface

because each vi has its rate limit commands that is gived from radius attribute AAA

as an example above:

rate-limit input 192000 36000 72000 conform-action continue exceed-action drop

rate-limit output 1120000 210000 420000 conform-action continue exceed-action drop

those two commands are given from AAA radius , and as a result we cant use service policy for all vi access with different speeds ,

i will try the follwoign solution

i found that radius attribtue can give the vi access a service policy command

i will try it and if it succeeded i will give u a reply ,

also , if you find a more easy solution for me for my issue above plz tell me it

regards

Ah, passing bandwidths via RADIUS - yea, that's a factoid worth knowing.

So, when I asked about using bandwidth percentages, you replaced all absolute values with percentages?  You also removed the max-bandwidth statement?

Unfortunately, a virtual template is one of the interfaces that's I have worked QoS on, and QoS features are often tied to "kinds" of interfaces often, but not always, improved in later IOS versions.

Router Dead , when i applied QOS on virtual-temp interface for v

hi ,

actually no

i applied percentages wihout  max bandwidht gurtantee removal ,

but i applied bw values with exit of gurantee removal

both failed !

================================

but you didnt tell me to update the ios ??

is ios 15 is better ?

==================================================

actually i dont want to down my router agian , it is on production network and all my pvc users will go down agian !

=================================

now im migrating to distibute service policy from AAA  radius and i will use shape instead of rate-limit like the above.

=============

plz give me ur opinion for rate-limit command ?  is it suitable for adsl customers ??

as i understand rate-limit==policing

but shaping is better than policing , especailly for customers

1st thing i will try shaping  with bw gurantee,

but if it got more my LNS consuption resources ,  i will go to policing with bw gurantee

you can see my next questiion here about shaping with bw gurtantee in the same time :

https://supportforums.cisco.com/message/4138322#4138322

agian ,

thanks alot for time and cooperation

with my best regards

New Member

Router Dead , when i applied QOS on virtual-temp interface for v

ohhhh god ,

another new problems agian !!

plz follow my question in radius attribute service policy !!!

https://supportforums.cisco.com/message/4141588#4141588

it cant access shaping and bw command !!
