Usage Guidelines
You must be in a user group associated with a task group that includes the proper task IDs. The command
reference guides include the task IDs required for each command. If you suspect user group assignment is
preventing you from using a command, contact your AAA administrator for assistance.
The bandwidth remaining command is used to set the Modified Deficit Round Robin (MDRR) weight for
the particular class.
When applied within an egress service policy, the command is used to define how any unallocated bandwidth
should be apportioned. It typically is used in conjunction with the bandwidth command. In such a
combination, if the minimum bandwidth guarantees are met, the remaining bandwidth is shared in the ratio
defined by the bandwidth remaining command in the class configuration in the policy map.
The available bandwidth is equally distributed among those queueing classes that do not have the remaining
bandwidth explicitly configured.
On egress, the actual bandwidth of the interface is determined to be the Layer 2 capacity excluding the
Note
Layer 2 encapsulation, but including the HDLC flags, FCS, and so on. These have to be included because
they are applied per packet, and the system cannot predict how many packets of a particular packet size
are being sent out.
