interface or PVC.

Setting the maximum available interface bandwidth

The maximum available interface bandwidth refers to the maximum interface bandwidth used for
bandwidth check when CBQ enqueues packets. It is not the actual bandwidth of the physical
interface.
If no maximum available bandwidth is set for an interface, the following bandwidth is used for CBQ
calculation:
•
The actual baud rate or rate if the interface is a physical one.
•
0 kbps if the interface is a virtual interface, for example, tunnel interface, Layer 3 aggregate
interface, or HDLC link bundle interface.
Configuration guidelines
•
As a best practice, set the maximum available interface bandwidth to be smaller than or equal
to the actual available bandwidth of the physical interface or logical link.
•
On subinterfaces, you must configure the bandwidth command to provide base bandwidth for
CBQ calculation.
•
You must configure the bandwidth command on a logical interface involved in load-sharing
interface backup.
Configuration procedure
To set the maximum interface available bandwidth:
Step
1. Enter system view.
2. Enter interface view.
3. Set
available bandwidth of
the interface.
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.
