Re: Cisco ASR1004 + ISG + RADIUS-based shaping

Konstantin Vinogradov · ‎06-19-2013

Hello!

I need to configure ISG with RADIUS-based shaping. There are two traffic classes: Internet (class-default) and Local Peering (PEERING-TRAFFIC). Class-default traffic must be shaped with committed rate with contract conditions (from billing via RADIUS, for example 2Mbit/sec), PEERING-TRAFFIC must be shaped with fixed commit rate 50Mbit/sec. I have tried many times and now I have this config (and it works):

Conprol Policy-Map

policy-map type control ISG-L3-ROUTED-CONTROL

class type control UNAUTH-DISCONNECT-CONDITION event timed-policy-expiry

10 service disconnect

!

class type control always event session-start

10 authorize aaa list ISG-RADIUS-LIST password ISG identifier source-ip-address

20 service-policy type service aaa list LOCAL-SERVICES name L4-REDIRECT-SERVICE

30 service-policy type service aaa list LOCAL-SERVICES name OPENGARDEN-SERVICE

100 set-timer UNAUTH-DISCONNECT-TIMER 10

QOS Policy-Maps

Policy Map ISG-GENERAL-POLICY-IN

Class PEERING-TRAFFIC

police cir 50000000 bc 1562500

conform-action transmit

exceed-action drop

Class class-default

service-policy ISG-CHILD-POLICY-IN

Policy Map ISG-GENERAL-POLICY-OUT

Class class-default

service-policy ISG-CHILD-POLICY-OUT

Policy Map ISG-CHILD-POLICY-OUT

Class PEERING-TRAFFIC

Average Rate Traffic Shaping

cir 50000000 (bps)

Class class-default

Policy Map ISG-CHILD-POLICY-IN

Class class-default

User-Authen RADIUS-Attributes

Attribute	Value
Idle-Timeout	40
Session-Timeout	180
Cisco-Account-Info	AISG-TRON-SERVICE-TEST

Service-Authen RADIUS-Attributes

Attribute	Value
Cisco-AVPair	ip:sub-qos-policy-in=ISG-GENERAL-POLICY-IN
Cisco-AVPair	ip:sub-qos-policy-out=ISG-GENERAL-POLICY-OUT
Cisco-AVPair	qos-policy-out=add-class(sub, (class-default), shape(100000000))
Cisco-AVPair	qos-policy-out=add-class(sub, (class-default, class-default), shape(2100000))
Cisco-AVPair	qos-policy-in=add-class(sub, (class-default), police(2000000))

I do not like this multiple “shape”: in parent policy and in child policy. I worry about device utilization. I can’t remove shaping with CIR 100Mbit/sec from parent out policy, because service policy installation failed in this case:

*Jun 19 14:13:00.713: Cannot attach queuing-based child policy to a non-queuing based class
*Jun 19 14:13:00.713: %QOS-6-POLICY_INST_FAILED:
Service policy installation failed

And I can’t remove all shaping to parent policy:

*Jun 19 14:14:37.708: SSS PM ERROR: Policy context is NULL or missing action in get aaa author passwd list APITraffic Shaping feature is not supported in user defined class of parent level policy
*Jun 19 14:14:37.716: %QOS-6-POLICY_INST_FAILED:
Service policy installation failed Traffic Shaping feature is not supported in user defined class of parent level policy

What is the right method in this case? May be I need to shape different traffic in different service? But I can’t define traffic class in RADIUS-attributes correctly.

Thank you!

hi Konstantin Vinogradov ,

have you found any solution for above query.? i do want same solution for my setup..

Thanks,

Bhumin Desai

Hi, bhumin.

Unfortunately I didn't found any other solution. Now I use configuration that I described in the first post. I have some problems with policng, but I think it depends on version of IOS.

hi Konstantin Vinogradov

, yesterday we have done it as below..may radius config and flow differ.

user service = P2P

Vendor	Attribute Code	Attribute Value
Default	Session-Timeout	86400
Cisco	Cisco-SSG-Account-Info	A1mbpsInternet
Cisco	Cisco-SSG-Account-Info	A10mbpsp2p

service 1 =A1mbpsInternet

Vendor	Attribute Code	Attribute Value
Cisco	cisco-avpair	ip:traffic-class=in default drop
Cisco	cisco-avpair	ip:traffic-class=out access-group name non-P2P-out
Cisco	cisco-avpair	ip:traffic-class=out default drop
Default	Service-Type	Outbound-User
Default	Download-QoS	1Mbps
Default	Upload-QoS	1Mbps
Cisco	cisco-avpair	ip:traffic-class=in access-group name non-P2P-in
Cisco	cisco-avpair	subscriber:accounting-list=PPP-USR

service 1 = A10mbpsp2p

Vendor	Attribute Code	Attribute Value
Default	Download-QoS	10mbps
Cisco	cisco-avpair	ip:traffic-class=in access-group name P2P-in
Cisco	cisco-avpair	ip:traffic-class=in default drop
Cisco	cisco-avpair	ip:traffic-class=out access-group name P2P-out
Cisco	cisco-avpair	ip:traffic-class=out default drop
Default	Upload-QoS	10mbps
Default	Service-Type	Outbound-User
Cisco	cisco-avpair	subscriber:accounting-list=PPP-USR

thats all...u just need to assigh service P2P with subscriber & u good to go..this way you can account/charge subscriber for what he/she use at actual.

the only prob m facing is.. m getting 2 sessions for subscribers in AAA server while only 1 in ASR... no other prob at all.

try it..

Bhumin.

Hi, Bhumin.

Sorry if I replying late.

About "Default Download-QoS 10mbps".

Is "10mbps" policy-map's name? Do you have it in your config?

Thank.

Best regards,

Konstantin.

Hello!

I have the similar problem, so I've decided to ask it here. I'm working on ISG configuration on ASR 1001x. It works OK, but I need to add a lot of new services with DSCP policies, like this:

policy-map 50m
 class class-default
  police cir 51200000 conform-action set-dscp-transmit af11 exceed-action set-dscp-transmit default violate-action set-dscp-transmit default

policy-map type service 50m-SRV
  service-policy input 50m
  service-policy output 50m

I wonder if I can make ASR download it from RADIUS as a usual service but with parameters. I've read about pQoS in Cisco Guide:

...
qos-policy-in=add-class(target ,(class-list ),qos-actions-list )
qos-policy-out=add-class(target ,(class-list ),qos-actions-list )
...

And it seems that's what I need, but I have some questions:

1) Is it possible to "stick" qos-policy-in and qos-policy-out on service?

2) The Guide said that: "...Parameterized QoS is not supported for IP sessions...". If I send it as service and not as session, is it allowed to use it with IP sessions?

Alex M · ‎11-08-2019

So, I've tried to apply QoS policy on service. it works, service has been applied:

SERVICE-TEST    Auth-Type := Accept
    User-Password == "cisco",
    Cisco-AVPair += "ip:sub-qos-policy-in=isgPolicy",
    Cisco-AVPair += "ip:sub-qos-policy-out=isgPolicy",
    Cisco-AVPair += "ip:qos-policy-in=add-class(sub, (class-default), police(15000000,0,0,transmit,drop,drop))",
    Cisco-AVPair += "ip:qos-policy-out=add-class(sub, (class-default), police(15000000,0,0,transmit,drop,drop))",
    Idle-Timeout =  "600"

But if I change action transmit to action set-ip-dscp(10) then error message "...wrong action set-ip-dscp(10)" appears in debug. Does anyone know how to solve this problem?
