R3303-HP HSR6800 Routers Layer 2 - WAN Command Reference

33
output-mbs: Specifies the maximum burst size for ATM cell output, which specifies the maximum number
of ATM cells that the output interface can cache. The value range is 1 to 512.
Usage guidelines
You can use this command as well as the service ubr, service vbr-rt and service cbr commands to set the
service type and rate-related parameters of a PVC. A newly configured PVC service type overwrites the
existing one.
Examples
# Create a PVC named aa, with the VPI/VCI value of 1/101.
<Sysname> system-view
[Sysname] interface atm 1/0/1
[Sysname-Atm1/0/1] pvc aa 1/101
# Specify the service type of the PVC as nrt-VBR, setting the peak bit rate of ATM cell to 100000 kbps,
the sustainable bit rate to 50000 kbps, and the maximum burst size to 320 cells.
[Sysname-atm-pvc-Atm1/0/1-1/101-aa] service vbr-nrt 100000 50000 320

service vbr-rt
Use service vbr-rt to set the service type of a PVC to RT-VBR and specify the related rate parameters in
PVC view.
Use undo service to restore the default.
Syntax
service vbr-rt output-pcr output-scr output-mbs
undo service
Default
The service type is UBR after a PVC is created.
Views

Default command level
2: System level
Parameters
output-pcr: Specifies the peak cell rate of ATM output (in kbps). For more information about the value
range, see Table 10.
output
-scr: Specifies the sustainable cell rate of ATM output (in kbps). Its value ranges are the same as
those of the output-pcr argument.
output-mbs: Specifies the maximum burst size of ATM cell output, which specifies the maximum cache
size of ATM cell output at the interface in cell number. The range of the value is 1 to 512. When it is used
in ATM E3 interface, the range of the parameter is 1 to 512.
