Configuration in the Controller Link Sharing (CLS) scheme.
Specifies the maximum VBR traffic that can be allocated
in a traffic direction on an interface. It is expressed
as a percentage of the maximum traffic direction's
bandwidth (applies after output pacing, for example).
This object interacts with MinVbr (if specified) such that
MinVbr <= MaxVbr.
This object interacts with MaxAgg (if specified) such
that MaxVbr <= MaxAgg.
Note that a change to this value affects subsequent
connection setup, not existing connections.
If the object is set to -1, the object is considered
to be unspecified.
This object is not instantiated for interfaces to which it
cannot be applied.
