Ryan,
When you use FRTS and CBWFQ with the bandwidth percentage parameter, the
percentage is based upon the minCIR value for FRTS.
HTH,

Subject: CBWFQ on Frame-Relay Interface
Hi, Group,
I want to classfiy two types of traffic and apply CBWFQ on 128k
Frame-Relay Interface. Does my configuration work on Frame-Relay
Interface?
The "show policy-map" seem ok
==========================
class-map match-all traffic-a
match access-group 15
class-map match-all traffic-b
match access-group 25
!
policy-map QOS
class traffic-a
bandwidth percent 25
class traffic-b
bandwidth percent 50
!
interface Serial0/0
bandwidth 128
service-policy output QOS
encapsulation frame-relay
!
R5#s policy-map interface s0/0
Serial0/0
Service-policy output: QOS
Class-map: traffic-a (match-all)
0 packets, 0 bytes
5 minute offered rate 0 bps, drop rate 0 bps
Match: access-group 15
Queueing
Output Queue: Conversation 265
Bandwidth 25 (%)
Bandwidth 32 (kbps) Max Threshold 64 (packets)
(pkts matched/bytes matched) 0/0
(depth/total drops/no-buffer drops) 0/0/0
Class-map: traffic-b (match-all)
0 packets, 0 bytes
5 minute offered rate 0 bps, drop rate 0 bps
Match: access-group 25
Queueing
Output Queue: Conversation 266
Bandwidth 50 (%)
Bandwidth 64 (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)
23 packets, 1243 bytes
5 minute offered rate 0 bps, drop rate 0 bps
Match: any
==========================
However, if I try to use Frame-Relay Traffic shaping together with
"service policy output", the bandwidth percent seem to be not correct.
25% traffic become 16k only. Why it changes ?
==========================
class-map match-all traffic-a
match access-group 15
class-map match-all traffic-b
match access-group 25
