Default Level
2: System level
Parameters
max-bandwidth value: Specifies the maximum bandwidth in kbps. The value argument ranges from 0
to 999994. The system default is 999994 kbps.
max-burstsize value: Specifies the maximum burst buffer size in bytes. The value argument ranges
from 0 to 8388480. The system default is 8388480 bytes.
