Multicast Rate
The multicast rate parameter determines the rate at which the
multicast queue is dequeued on the ATM FCP. The default
value is 1/8 (12.5%) of the channel rate. You can select the
multicast shaping rate as a fraction of the line rate, from 1/15
to 1. The rate is configured per IOM.
Note: There is only one multicast queue per ATM FCP.
Traffic Pace
Select traffic pacing on the IOM. Traffic pacing prevents cell
loss during Frame Relay-to-ATM Interworking. There is a
slight reduction in throughput.
Enable – Select the check box to enable traffic pacing on the
IOM.
Disable
–
(default) Clear the check box to stop
traffic pacing
on the IOM
.
VBR Rt Shaping
Select traffic shaping for VBR RT traffic (based on the Frame
Relay parameters set for this circuit).
Enable – Select the check box to enable traffic shaping for
VBR RT traffic.
Disable
–
(default) Clear the check box to stop
traffic
shaping for VBR RT traffic
.
Note: You must enable the Traffic Pace field.
VBR Nrt Shaping
Select traffic shaping for VBR NRT traffic (based on the
Frame Relay parameters set for this circuit).
Enable – Select the check box to enable traffic shaping for
VBR NRT traffic.
Disable
–
(default) Clear the check box to stop
traffic
shaping for VBR NRT traffic
.
Note: You must enable the Traffic Pace field.
Prioritization of
Traffic
Select whether traffic is ordered by priority. The priority
levels from highest to lowest are VBR-RT, VBR-NRT, and
unspecified bit rate (UBR).
Enable – Select the check box to order traffic by priority.
Disable
–
(default) Clear the check box to stop ordering
traffic by priority.
Note: Enabling traffic prioritization results in a reduction of
throughput.
