[cisco-bba] ASR1K LNS

Hi All,

I guess a while back many people moved their PPP subscribers over to
ASR1Ks and ASR9Ks etc, probably mostly from 7200/7300/7600 series
devices and similar.

I'm finally looking at moving over users with QoS and I'm having
several issues as it goes, but the very first one I want to tackle is
just applying a basic shaper. This shaper is shaping to 95% of 1G not
95% of the uer session :( Even though the LNS nows the subscriber
speed (i.e. the LAC is sending it over in the L2TP call setup):


policy-map CPE-DSL-QOS-PARENT-OUT
 class class-default
  shape average percent 95
   service-policy CPE-DSL-QOS-PE-OUT

lns1-lhclon.core#show policy-map interface vi2.1

 Virtual-Access2.1

 SSS session identifier 1 -

  Service-policy output: PE-DSL-QOS-PARENT-OUT

    Class-map: class-default (match-any)
      7 packets, 588 bytes
      30 second offered rate 0000 bps, drop rate 0000 bps
      Match: any
      Queueing
      queue limit 665 packets
      (queue depth/total drops/no-buffer drops) 0/0/0
      (pkts output/bytes output) 0/0
      shape (average) cir 950000000, bc 9500000, be 9500000
      target shape rate 950000000


Any one seen this, fixed it?

The core-facing interfaces on this ASR1002-X (IOS-XE 03.13.04.S,
15.4(3)S4) are a 2x1G etherchannel.

Cheers,
James.
