SE/PVC Configuration Parameters
• The CIR if the BIR is not effective or if congestion occurred while running at the
BIR.
A full explanation of how to fine tune the CIR and BIR appears in the section
Information Rate Parameters in the Extended Parameters fascicle of this document
series.
5.5.4 Burst Information rate
NOTE: This parameter is not used for PVCs in ATMPVCR or ATM-MULTIPLEX
mode. Consult “Service Categories” on page 1-10 for a description of all factors
that affect cell rate pacing when these modes are selected.
Values: 4000 - 6144000
Default: 56000
Console SNMP Text-based Config
Burst Information rate atmpvcBurstInfoRate [atmpvc#] BurstInfoRate
PVC Burst Information Rate (BIR) in bits per second. The BIR represents the data
throughput when the PVC is in burst mode. For example, if you configure the BIR at
64000 bps and the CIR at 56000 bps, the NetPerformer will transmit at 64000 bps unless
congestion occurs, when the rate will be reduced to 56000 bps.
NOTE: Two Extended Parameters also control the information rate of Frame Relay
connections. Together these parameters can be used to adjust the committed
and burst rate sampling timers on networks that integrate bursty high-speed
traffic with constant low-speed traffic. They are described in the section
Information Rate Parameters in the Extended Parameters fascicle of
this document series.
NOTE: This parameter is not used for PVCs in ATMPVCR or ATM-MULTIPLEX
mode. Consult “Service Categories” on page 1-10 for a description of all factors
that affect cell rate pacing when these modes are selected.
Values: 4000 - 6144000
Default: 56000
