R2511-HP MSR Router Series ACL and QoS Command Reference(V5)

107
The bandwidths assigned for AF and EF in a policy must have the same type, bandwidth or percentage.
After the queue ef bandwidth pct percentage [ cbs-ratio ratio ] command is used, CBS equals (Interface
available bandwidth × percentage × ratio)/100/1000.
After the queue ef bandwidth bandwidth [ cbs burst ] command is used, CBS equals burst. If the burst
argument is not specified, CBS equals bandwidth×25.
Examples
# Configure EF in traffic behavior database, with the maximum bandwidth as 200 kbps and CBS as
5000 bytes.
