PVC view, ATM class view
Default command level
2: System level
Parameters
output-pcr: Specifies the output peak rate of an ATM cell (in kbps). The value range for this parameter
varies with interface types, as shown in Table 46.
Table 46 Value ranges
for the
output-pcr argument
Interface type Value range for output-pcr
ADSL 2+ 64 to 640
G.SHDSL
• For two-wire interfaces or four-wire interfaces in
two-wire mode: 64 to 2312
• For four-wire interfaces: 128 to 4624
ATMOC3/STM-1 64 to 155000
ATM OC12/STM-4 64 to 622000
ATM E1 64 to 1920
ATM T1 64 to 1536
ATM E3 64 to 34000
ATM T3 64 to 44000
cdvt-value: Specifies the cell delay variation tolerance in μs. The effective range is 0 to 10,000 μs and the
default is 500 μs. This argument cannot be configured in ATM class view.
Usage guidelines
Configure the PVC with greater bandwidth first and then the one with smaller bandwidth. If you fail to
configure them, increase the cdvt-value and try again. In the command line, the system will prompt you
on this.
"fail to set service parameter, please adjust cdvt value"
The command is not applicable to ATM E1 interfaces and ATM E3 interfaces.
Examples
# Create a PVC named aa, with the VPI/VCI value of 1/101.
<Sysname> system-view
[Sysname] interface atm 1/0
[Sysname-Atm1/0] pvc aa 1/101
# Specify the service type of the PVC as CBR and the peak rate of an ATM cell as 50000 kbps, and the
cell delay variation tolerance as 1000 μs.
[Sysname-atm-pvc-Atm1/0-1/101-aa] service cbr 50000 cdvt 1000
