Yeah, you can do that; depends (of course!) on code version and platform,  
but see if you have something like

class-map match-all foo
   match ip precedence 4
!
!
policy-map bar
   class foo
    set mpls experimental imposition 5
!

available in your CLI; do that on the customer-facing interface.

Yeah, but not all CEs are managed.  In my experience, in the US it tends  
to be about 80% unmanaged CE and 20% managed; most of the rest of the  
world, it's the other way around.

RE: : do PNNI has relevance to MPLS

There isn't much  you mention about what kind of
requirements you have for PNNI and MPLS.

But to give you a general idea, there is ATM/MPLS interworking
standard in ATM Forum which allows PE boxes to tunnel PNNI
control messages over MPLS based PWs. Each signaled data VC is
then mapped to MPLS PW whose labels were exchanged during 
PNNI signaling.

Find more details in af-aic-0178.001 and af-cs-0197.000.

There is also some work going on in the same area in MPLS Forum,
but it is at very early stage to comment on.

RE: : MPLS-OPS List Now Available via NNTP

Hi,

Is there any free downloadable software for MPLS simluator in Windows ?
i.e some kind of traffic generator which generates MPLS packets.

thanks in advance,

Re: : Mapping customer traffic on a specific LSP

I agree with eric. This makes it difficult in most cases out here in the 
asian region, wherein most of the ce's are'nt managed by the SP. Just to get 
into somemore detail.. I have seen something similar on the Juniper 
equipment to achieve the differential services, wherein you have 
"classifiers" configured for manually forcing an "exp-code-point" write on 
the edge, and then you have some schedulers which are configured in a way to 
force trafic profiles such as "bandwidth/PLP/Drop profiles etc.. associated 
with the code point values. These traffic profiles essentially help in 
treating the marked packets on their merits. In the core you have similar 
profile configs & classifiers which also ensure that preferential treatment 
is extended to traffic along the core as well.

Is there something similar to this on the cisco gear. It would be great if I 
could have a sample config in brief to check this out.

TIA,

Neil

Sounds like what you want is:

at the edge, match DSCP/IPPrec and set EXP to be imposed
in the core, queued according to imposed EXP

right?

If so, http://www.cisco.com/warp/public/cc/pd/iosw/tech/mpotc_qp.htm shows  
that the edge config is:

!
class-map match-all PREMIUM
  match ip dscp ef
class-map match-all BUSINESS
  match ip dscp af31 af32 af33
!
policy-map IN-POLICY
  class PREMIUM
   police 128000 4000 4000 conform-action set-mpls-exp-transmit 5  
exceed-action drop
  class BUSINESS
   police 256000 8000 8000 conform-action set-mpls-exp-transmit 4  
exceed-action set-mpls-exp-transmit 3
  class class-default
   set mpls experimental 0
!
interface Serial0/0
  ip address 10.32.14.2 255.255.255.0
  service-policy input IN-POLICY

The core config depends on platform and code version, but it's generally  
something along the lines of

class-map match-all PREMIUM
  match mpls exp 5

policy-map out
  class PREMIUM
   bandwidth percent 99

Re: : Mapping customer traffic on a specific LSP

Hi,

Many thanks for the configs, Thats exactly what i was looking for. In regard 
to the config given, I have a few queries.

class-map match-all PREMIUM
  match ip dscp ef
class-map match-all BUSINESS
  match ip dscp af31 af32 af33

Query: What is the significance of the "match ip dscp ef" statement? Does 
exp code-point 5 map to the ef class? Or can we just use say "match mpls 
experimental 5".

policy-map IN-POLICY
  class PREMIUM
   police 128000 4000 4000 conform-action set-mpls-exp-transmit 5
exceed-action drop
  class BUSINESS
   police 256000 8000 8000 conform-action set-mpls-exp-transmit 4
exceed-action set-mpls-exp-transmit 3
  class class-default
   set mpls experimental 0

Query: Assuming I am am going mark all traffic coming from a particular vpn 
customer to a specific class, Can I have multiple policy map statements each 
having definitions for a particular class. For e.g..I have a policy map 
called "premium map" with a class definition for only the premium class, and 
so on..Then I tie the respective policy map definitions to specific vrf 
interfaces.

The core config depends on platform and code version, but it's
generally  something along the lines of

class-map match-all PREMIUM
  match mpls exp 5

policy-map out
  class PREMIUM
   bandwidth percent 99

Query: I assume that the core requires the following statements as well.

interface Serial1/0
ip address 10.31.14.2 255.255.255.0
service-policy output out

Kindly advise,

TIA,

Neil

see
http://www.cisco.com/warp/public/105/dscpvalues.html

IP DSCP EF is used for matching on DSCP bits in an IP packet; 'match mpls  
exp 5' is for matching on MPLS packets.  So it depends on what you want to  
match.

Not sure I understand the question.  As far as I know, you can mix and  
match policy-maps and class-maps.  So what I think you're asking is  
whether you can do

policy-map foo
  class bar

policy-map baz
  class bar

right?  That, you can do.

Yes.  QoS in the core is not always the same as at the edge, as many  
people apply more granular QoS at the edge, since it tends to need it  
less.  But any QoS you want to apply in the core, you need to do with the  
policy-map/class-map/service-policy trio.

Re: : CBTS - Mapping customer traffic on a specific LSP

guys, could anyone point me in the direction of some documentation of the 
CBTS feature? I had a dig around cco, but couldn't see anything (might have 
missed it).

thanks a lot.
