Setting the maximum reserved bandwidth as a percentage of available bandwidth
The maximum reserved bandwidth is set on a per-interface basis. It decides the maximum bandwidth assignable for the QoS queues on an interface. It is typically set no greater than 80% of available bandwidth, considering the bandwidth for control traffic and Layer 2 frame headers.
Use the default maximum reserved bandwidth setting in normal cases. When tuning the setting, make sure that the Layer 2 frame header plus the data traffic is under the maximum available bandwidth of the interface.
To configure the maximum reserved bandwidth on an interface:
