Juan,
When you are configuring FRTS through the MQC, the command
"frame-relay traffic-shaping" is not enabled on the interface. Instead,
the available bandwidth is determined by what the shape adaptive command
says like in the following example:
policy-map X
class class-default
shape average 64000 4000
shape adaptive 48000
!
map-class frame-relay FRTS
service-policy output X
!
interface Serial0/0
encapsulation frame-relay
frame-relay class FRTS
Rack2R4#show policy-map interface serial0/0
Serial0/0: DLCI 401 -
Service-policy output: X
Class-map: class-default (match-any)
0 packets, 0 bytes
5 minute offered rate 0 bps, drop rate 0 bps
Match: any
Traffic Shaping
Target/Average Byte Sustain Excess Interval
Increment
Rate Limit bits/int bits/int (ms) (bytes)
64000/64000 1000 4000 4000 62 500
Adapt Queue Packets Bytes Packets Bytes Shaping
Active Depth Delayed Delayed Active
BECN 0 0 0 0 0 no
Rack2R4#show traffic-shape queue serial0/0
Traffic queued in shaping queue on Serial0/0
Traffic shape class: class-default
Queueing strategy: weighted fair
Queueing Stats: 0/1000/64/0 (size/max total/threshold/drops)
Conversations 0/0/16 (active/max active/max total)
Reserved Conversations 0/0 (allocated/max allocated)
Available Bandwidth 48 kilobits/sec
The "available bandwidth 48" shows that this value is bounded by the
shape adaptive command. This is analogous to the "frame-relay mincir"
value with legacy FRTS.
