On FR, you need to use a map-class as follows:
Rack1R1#sh run policy
Building configuration...
Current configuration : 77 bytes
!
policy-map SHAPER
class class-default
shape average 64000 640 0
!
end
Rack1R1#sh run map
Building configuration...
Current configuration:
!
map-class frame-relay SHAPE
service-policy output SHAPER
end
Rack1R1#sh run int s1/0.1
Building configuration...
Current configuration : 129 bytes
!
interface Serial1/0.1 point-to-point
ip address 10.1.31.1 255.255.255.0
frame-relay interface-dlci 103
class SHAPE
end
Rack1R1#
Rack1R1#sh policy-map int s1/0.1
Serial1/0.1: DLCI 103 -
Service-policy output: SHAPER
Class-map: class-default (match-any)
4 packets, 1284 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 80 640 0 10 80
Adapt Queue Packets Bytes Packets Bytes Shaping
Active Depth Delayed Delayed Active
- 0 4 1284 0 0 no
