–
2 = Variable bit rate real time—VBR (RT)
–
3 = Variable bit rate non-real time—VBR (NRT)
–
4 = VBR (RT) 3
–
5 = VBR (RT) 2
–
6 = VBR (NRT) 2
–
7 = VBR (NRT) 3
•sus-cell-rate (sustained cell rate, defined as cells per second):
–
In the range from 15 to the value you specified for the peak-cell-rate argument.
•max-burst-rate (maximum burst rate, defined as cells per second):
–
In the range from 1 to 10 times the value you specified for the sus-cell-rate argument.
Step 3 Type the addconloop command, the lcn argument value, and press Enter to set a loopback on a VISM
PVC with the loopback in the direction of cellbus. Specify the lcn argument value with a value in the
range from 131 to 510.

–
1 = On
–
2 = Off
