Hi:
 
I would appreciate some comments.

 

I have the following scenario:

 

In HQ I have a physical serial interface with 2 PVCs: DLCI 201 to BR1 with CIR 
384kbps and DLCI 202 to BR2 with CIR 1544kbps.

 

I assume I need to configure frame-relay fragment for DLCI 201 with fragment 
size equal to 480 but my questions are:

 

1.      Do I need to create 2 map-class, one for each DLCI with appropriate 
values of cir, mincir, bc, be? 
2.      Do I need to configure frame-relay fragment for DLCI 202 although is a 
High Speed link (>768kbps) in order to not affect traffic on the same interface 
of DLCI 201?

 

          map-class frame-relay br1                ! applied to dlci 201

             frame-relay fragment 480

             frame-relay cir 364800

             frame-relay mincir 364800

             frame-relay bc 3648

             frame-relay be 0

            no frame-relay adaptive shaping becn

            service-policy output llq

 

          map-class frame-relay br2                ! applied to dlci 202

             frame-relay fragment 480                 <------in order to does 
not affect the trafic of the dcli 201 on the same interface

             frame-relay cir 1466800

             frame-relay mincir 1466800

             frame-relay bc 14668

             frame-relay be 0

            no frame-relay adaptive shaping becn

            service-policy output llq2

 

Acording to this tech-note any other PVCs that share the same physical 
interface need to configure the fragmentation to the size used by the voice PVC

But in this one the configuration shows to diferent sizes for fragments in the 
same interface.

Thanks for your help.
