Greetings all. I have a Cisco 1600 router oand im trying to get it to activate traffic shaping. My Cisco 2600s are active but the 1600s are unable. a show pvc gives me this

PVC Statistics for interface Serial0 (Frame Relay DTE)

DLCI = 46, DLCI USAGE = LOCAL, PVC STATUS = ACTIVE, INTERFACE = Serial0.1

  input pkts 296736        output pkts 280416       in bytes 271200909
  out bytes 50347136       dropped pkts 0           in FECN pkts 291      
  in BECN pkts 0           out FECN pkts 0          out BECN pkts 0

  shaping inactive    
  traffic shaping drops 0

Here is my show run for the serial interface

 ip address x.x.x.x y.y.y.y
 no ip mroute-cache

 frame-relay interface-dlci 46  

map-class frame-relay cir128kbps
 frame-relay cir 128000
 frame-relay bc 16000
 frame-relay be 0

Why do you think that this is not working? If the command shaping inactive is leading you to this conclusion then bare in mind that this will change in real time to active when:

1. BECNs are received and DLCI has been configured to shape to BECNs.

2. The number of data bytes to transmit out of an interface are more than the available credit (byte limit) in a given interval (Tc).

Since there have been no BECNs recieved the traffic shaping is inactive, i.e. the traffic is not currently being shaped, even though it can be if the network thresholds are exceeded
