Hi guys,
I configured the following frame relay shaping parameters on an interface with
2 p2p sub-interfaces:
map-class frame-relay SHAPE
frame-relay cir 256000
frame-relay bc 2560
frame-relay fair-queue
frame-relay fragment 320
I then applied this class to the physical interface with the command, frame
class SHAPE, thinking that each sub-interface will inherit the parameters I
had already configured.
Then I configured MQC to prioritize voice traffic by doing the following:
class-map match-all VOIP
match access-group 100
!
!
policy-map VOIP
class VOIP
priority 200
But, when I tried to apply to service-policy to the map-class frame-relay, I
got the following console message:
I/f Serial1/0 DLCI 301 class VOIP requested bandwidth 200 (kbps), available
only 128 (kbps)
I did a show traffic-shaping and got this:
Rack1R3#SH TRAFfic-shape
Interface Se1/0
Access Target Byte Sustain Excess Interval Increment Adapt
VC List Rate Limit bits/int bits/int (ms) (bytes) Active
301 256000 320 2560 0 10 320 -

305 256000 320 2560 0 10 320 -
It seems like the router is taking the 256k cir and dividing up between the 2
sub-interfaces so that only 128k is available rather than giving each dlci
256k of cir. Is this what is going on?
I also tried to apply the map-class to each dlci individually and got the same
error message. So now I can't apply the service-policy to either the physical
interface or to the individual sub-interfaces.
How do I fix this problem?
Any help or advice would be greatly appreciated.
TIA, Tim
