Hi guys,

The objective of this task was to configure a guaranteed amount of bandwidth
(80%) for certain traffic

transiting over a F/R link with 384000 kbps.

To do this, I configured this:

policy-map TASK9.2
  class TASK9.2
     bandwidth percent 80

map-class frame TASK9.2
fram mincir 384000
service-policy output TASK9.2

Then to check if all was well, I did a show fram pvc 501 and this was the
output:

Rack1R5#sh fram pvc 501

PVC Statistics for interface Serial0/0 (Frame Relay DTE)

DLCI = 501, DLCI USAGE = LOCAL, PVC STATUS = ACTIVE, INTERFACE =
Serial0/0.501

  input pkts 3253 output pkts 23940 in bytes 4829829
  out bytes 18164267 dropped pkts 0 in pkts dropped 0
  out pkts dropped 0 out bytes dropped 0
  in FECN pkts 0 in BECN pkts 0 out FECN pkts 0
  out BECN pkts 0 in DE pkts 0 out DE pkts 0
  out bcast pkts 23920 out bcast bytes 18162187
  5 minute input rate 1000 bits/sec, 0 packets/sec
  5 minute output rate 4000 bits/sec, 1 packets/sec
  pvc create time 07:48:57, last time pvc status changed 07:47:37
  cir 56000 bc 7000 be 0 byte limit 875 interval 125
  mincir 384000 byte increment 875 Adaptive Shaping none
  pkts 558 bytes 421217 pkts delayed 12 bytes delayed 2862
  shaping inactive
  traffic shaping drops 0
  service policy TASK9.2
 Serial0/0.501: DLCI 501 -

  Service-policy output: TASK9.2

    Class-map: TASK9.2 (match-all)
      0 packets, 0 bytes
      5 minute offered rate 0 bps, drop rate 0 bps
      Match: access-group name HTTP-BACK
      Queueing
        Output Queue: Conversation 41
        Bandwidth 80 (%)
        Bandwidth 307 (kbps) Max Threshold 64 (packets)
        (pkts matched/bytes matched) 0/0
        (depth/total drops/no-buffer drops) 0/0/0

    Class-map: class-default (match-any)
      325 packets, 244728 bytes
      5 minute offered rate 4000 bps, drop rate 0 bps
      Match: any
  Output queue size 0/max total 600/drops 0

Notice the cir and mincir and other shaping values:

cir 56000 bc 7000 be 0 byte limit 875 interval 125
  mincir 384000 byte increment 875 Adaptive Shaping none
  pkts 558 bytes 421217 pkts delayed 12 bytes delayed 2862

-----------------------------------------------------------------------------

What does this mean?  cir 56000 and mincir 384000

How is it possible to have a mincir value higher than the cir?

TIA, Tim
