Configuring Frame Relay Services
•
Scaling limitations may apply on the number of PVCs that can be supported
with FRF.12 on an interface or slot, especially for routers such as the BN that
provide VC aggregation in an end-to-end frame relay network.
These scaling limitations are affected by the processor speed, the fragment
size (and the size of the data packet to be fragmented), and the number of
PVCs that implement FRF.12 on the slot.
Configuring FRF.12 Fragmentation and Interleaving
To configure FRF.12 fragmentation and interleaving on the router, you must
enable traffic shaping and FRF.12 fragmentation on the frame relay PVCs and
configure DSQMS parameters on the interface associated with the PVCs.
Note: To implement FRF.12 fragmentation and interleaving, you may also
need to configure ingress traffic filters to mark VoIP packets with the EF
DSCP. For instructions on configuring ingress traffic filters, see Chapter 3 of
Configuring Differentiated Services (part number 308620-14.20 Rev 00).
You can use the BCC or Site Manager to configure FRF.12 fragmentation and
interleaving on the router. By default, FRF.12 fragmentation and interleaving are
disabled.
Configuration Steps
To configure FRF.12 fragmentation and interleaving on the router, perform the
following steps. These steps are described in detail in the following sections.
1.
Configure DSQMS on the interface.
If necessary, add DSQMS to the list of protocols on the interface.
2.
Configure traffic shaping on the PVC or PVCs.
Set values for these traffic shaping parameters: committed information rate
(CIR), committed burst, and excess burst.
3.
Enable FRF.12 fragmentation on the PVCs and reset the data packet
fragmentation size if necessary.
4.
Enable FRF.12 interleaving on the interface and reset the weighting of data
packet fragments and voice packets in the stream, if necessary.
