Multipoint frame relay traffic shaping ?

[philipbarker]

Hi,

I configure a hub & spoke topology with the hub as a multipoint interface and the spokes as physical. Is there a way to configure traffic shaping on a per PVC basis ? Or do I need to opt for point-to-point to achieve this ?

Regards,

Phil.

Hi,

Found out how to do this with :

under the frame-relay interface-dlci command using 'class' command.

Make believe you want to allocate 128kbps to Spoke2 and 192kbps to Spoke3.

Config at the Hub:

interface Serialx/x

no ip address

encapsulation frame-relay

serial restart-delay 0

no fair-queue

frame-relay traffic-shaping

!

interface Serial1/0.1 multipoint

ip address 192.168.123.1 255.255.255.0

frame-relay map ip 192.168.123.2 102 broadcast

frame-relay map ip 192.168.123.3 103 broadcast

frame-relay interface-dlci 102

class DLCI102

frame-relay interface-dlci 103

class DLCI103

!

!

map-class frame-relay DLCI102

frame-relay cir 128000

frame-relay bc 12800

!

map-class frame-relay DLCI103

frame-relay cir 192000

frame-relay bc 19200

!

Verification:

Rack1R1#sh frame pvc 102 | i cir

cir 128000 bc 12800 be 0 byte limit 1600 interval 100

mincir 64000 byte increment 1600 Adaptive Shaping none

Rack1R1#sh frame pvc 103 | i cir

cir 192000 bc 19200 be 0 byte limit 2400 interval 100

mincir 96000 byte increment 2400 Adaptive Shaping none

HTH,

Hi Edison,

Thanks Edison, I had just worked that bit out, however, the above snippet gives me another question. You have both a static mapping and a dynamic mapping for your dlci 102 ???

Is this normal and either way what does 'sh frame map' indicate for the pvc ? i.e is it static or dynamic ?

Regards,

Phil.

Indicates static. The first command was there in the original configuration. The second command was added when implementing frame-relay traffic shaping. You need to place the shaping class under the interface-dlci subcommand.
