Hi Group,

Would appreciate you someone confirms that the below configurations is
correct for voice-adaptive FR shaping (no fragmentation needed):

! priority traffic in ACL101
class-map match-all VOICE
 match access-group 101

policy-map PRIORITY
 class VOICE
  priority 10

policy-map PARENT
 class class-default
  shape average 128000
  shape adaptive 64000
  shape fr-voice-adapt deactivation 31
  service-policy PRIORITY

map-class frame-relay RADO
 service-policy output PARENT

interface Serial1/1
 no ip address
 encapsulation frame-relay
 no fair-queue

interface Serial1/1.1 point-to-point
 ip address 192.168.45.4 255.255.255.0
 frame-relay interface-dlci 1000
  class RADO

Specifically, do I need FRTS enabled on the main interface (DocCD
doesn't mention such requirement)? Anything else I am missing? I'm
asking because even when I'm sending a lot of traffic as defined in
ACL101 (high priority), i don't see the adaptive shaping to be declared
as "active", although packets are counted as delayed:

Router#sh policy-map int se 1/1.1
 Serial1/1.1: DLCI 1000 -

  Service-policy output: PARENT

    Class-map: class-default (match-any)

thanks,
Rado
