Usage guidelines
If the packet direction is not specified, the CBS is effective for both incoming packets and outgoing
packets.
CBS is the traffic that an FR network is committed to send in an interval of Tc. If no congestion occurs, the
FR network guarantees the traffic of CBS is sent.
Examples
# Set CBS to 64000 bits for both incoming packets and outgoing packets of the FR class test1.
