Traffic Management
The PA-A2 ATM CES port adapter supports the traffic-shaping parameters defined in
Table 4-2
. This
ensures that generated traffic conforms to the ATM Forum Traffic Management Specification Version
4.0. Shaping values are configured using the vbr-nrt command in VC configuration mode.
Note
For more information about traffic management specific to the various class of service categories, refer
to the ATM Technical Tips on Cisco.com.
Table 4-2
Traffic-Shaping Parameters and Ranges
Traffic Parameter
Range
Default
T3
56 kbps to 45 Mbps
If the peak rate is not defined,
each new VC is set to the
maximum physical layer rate.
The VC is assigned to the UBR
service category.
E3
56 kbps to 34 Mbps
If the peak rate is not defined,
each new VC is set to the
maximum physical layer rate.
The VC is assigned to the UBR
service category.
OC-3c Peak Rate
56 kbps to 155 Mbps
If the peak rate is not defined,
each new VC is set to the
maximum physical layer rate.
The VC is assigned to the UBR
service category.
Average Rate
0 < average < peak rate
Average = peak rate at the
maximum physical layer rate.
Maximum Burst
Size
1 to 64,000 cells
Equal to the PA-A2 ATM CES
port adapter MTU size.
