Default command level
2: System level
Parameters
bandwidth: Bandwidth in the range of 8 to 1000000 kbps.
cbs burst: CBS in the range of 32 to 2000000 byte. The default is bandwidth × 25.
pct percentage: Percentage of the maximum available bandwidth in the range of 1 to 100.
cbs-ratio ratio: Allowed burst ratio in the range of 25 to 500. This default is 25.
Usage guidelines
The command cannot be used in conjunction with the queue af command, the queue-length command,
or the wred command in traffic behavior view.
In a policy, the default class cannot be associated with the traffic behavior that has the queue ef
command.
The total bandwidth assigned for AF and EF in a policy must be no more than the maximum available
bandwidth of the interface where the policy is applied.
The total percentage of the maximum available bandwidth assigned for AF and EF in a policy must be
no more than 100.
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.
