Hi Everyone,
I would like your assistance or input with the following QOS scenario
The scenario: R5 has a point to point FR subinterface to R1, and a point
subinterface to R3, R4. Access rate at R1, R3 and R5 are 64Kbps, 64Kbps and
T1 respectively. Each DLCI is provisioned with a CIR of 56Kbps.
The task: Configure MQC-only traffic shaping at CIR for the R5-R1 and R5-R3
PVCs at CIR target rate, with excess burst to AR. Configure CBWFQ for the
R5-R3 PVC with voice traffic limited to 32Kbps and a burst of 4000bytes in a
second.

-------------------R1
/
R5---< FR

My solution at R5:
R5
class-map VOICE
match ip rtp 16384 16383
class-map FR_PVC_503
match fr-dlci 503
class-map FR_PVC_504
match fr-dlci 504
policy-map CBWFQ
class VOICE
priority 32 4000
policy-map SHAPE
class FR_PVC_503
shape average 56000 7000 1000
service-policy CBWFQ
class FR_PVC_504
shape average 56000 7000 1000
int s1/0
service out SHAPE
int s1/0.345 mult
band 64
int s1/0.1 point
band 64
Problem: When I verify shaping using "show policy-map int s1/0", and
generate some transit traffic to trigger shaping, my solution works fine.
How can I verify available bandwidth for the R5-R3 PVC, since I have CBWFQ
on that PVC? I tried using "show queueing int s1/0" without success.
TIA
Ben
