Usage Guidelines
Bandwidth, bandwidth remaining, shaping, queue-limit and WRED commands can be configured together in
the same class.
The bandwidth remaining command is supported only in the egress direction.
Note
The available bandwidth is equally distributed among those queueing classes that do not have the remaining
bandwidth explicitly configured.
The bandwidth remaining command is used to proportionally allocate bandwidth to the particular classes,
but there is no reserved bandwidth capacity.
On egress, if the bandwidth remaining command is not present, then the bandwidth is shared equally among
the configured queueing classes present in the policy-map.
