DSL over L2TP Basic Shaper

Within IOS it is possible for logical interfaces to not experiance congestion. Once a shaper has been created on a logical interface then the interface can experiance congestion and prioritisation can take effect. NOTE: ASK9Ks support subscriber:sub-qos-policy-in/out here.

# Example applying a QoS policy on RADIUS to VAI on the LNS
# (per-session QoS) Cisco-AVPair = "ip:sub-qos-policy-out=PM-Shape-DSL" # On the LNS: # # show subscriber sess | inc adsl-user-01 # 195 Vi37 authen Local Term adsl-user-01 01:02:03 # # show policy-map int virtual-access 37 Applying a police to a VAI: policy-map PM-ADSL-8M-POLICE class class-default police 8000000 Cisco-AVPair = "ip:sub-qos-policy-out=PM-ADSL-8M-POLICE" # Legacy style config # Cisco-AVPair = "lcp:interface-config=service-policy output PM-ADSL-8M-POLICE" Sometimes to apply a shape the legacy style AV pair is required: policy-map PM-ADSL-8M-SHAPE class class-default shape average 8000000 Cisco-AVPair = "lcp:interface-config=service-policy output PM-ADSL-8M-SHAPE" Shapes can be made using a 100% bandwidth parent tunnel to then carve out feature like voice: class-map match-all CM-VOIP match access-group 100 ! policy-map PM-PRIORITY-VOIP class CM-VOIP-Traffic ! Guarantee 200Kbps for voice bandwidth 200 ! policy-map PM-SHAPE-ADSL-WITH-VOICE class class-default ! Shape to 100% (LAC should pass line sync speed over L2TP to our LNS) shape average percent 100 service-policy PM-PRIOITY-VOIP ! Cisco-AVPair = "ip:sub-qos-policy-out=PM-SHAPE-ADSL-WITH-VOICE"
