Setting the maximum reserved bandwidth as a percentage of
available bandwidth
The maximum reserved bandwidth is set on a per-interface basis and 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 most situations. When tuning the setting, make
sure 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:
