Usage guidelines
Before you collect traffic statistics within a specific time period on an interface, clear the existing
statistics for the interface.
If you do not specify the virtual-ethernet keyword, this command clears statistics for all interfaces.
If you specify the virtual-ethernet keyword but do not specify the interface-number argument, this
command clears statistics for all VE interfaces.
If you specify both the virtual-ethernet keyword and the interface-number argument, this command
clears statistics for the specified VE interface.
Examples
# Clear statistics for the interface Virtual-Ethernet 2/4/1.
<Sysname> reset counters interface virtual-ethernet2/4/1
service cbr
Use service cbr to set the PVC service type to CBR and set the related parameters.
Use undo service to restore the default.
Syntax
service cbr output-pcr [ cdvt cdvt_value ]
undo service
Default
The service type of a PVC is UBR. The peak output rate of ATM cells equals the maximum
bandwidth of the interface to which the PVC belongs.

Parameters
output-pcr: Specifies the peak output rate of ATM cells in kbps. Table 47 shows the value ranges for
the output-pcr argument on different interfaces.
Table 47 Peak output rate value ranges
Peak output rate value range
ATM ADSL2+ 64 to 640
ATM SHDSL_4WIRE 128 to 4624
ATM SHDSL_8WIRE_BIS 256 to 22784
ATM OC-3c/STM-1 64 to 155000
ATM subinterface
Same as that of the ATM interface to which the ATM
subinterface belongs.
PVC-group
Same as that of the ATM interface to which the
PVC-group belongs.
cdvt cdvt_value: Specifies the cell delay variation tolerance in the range of 0 to 10000 μs. The
default is 500 μs, which means that the maximum cell delay is 500 μs.
