Each entry defines a set of configurable thresholds
and parameters for each monitored scheduling service
for an upstream channel.
Scheduling service can be specified by a scheduling
type or QoS Service class name.
A set of thresholds applied by cable admission control
in the process of monitoring upstream channel bandwidth.
The following classes of upstream policies can be
configured:
1. Global
An entry with a ccacUsConfigIfIndex of '0' identifies
a global policy.
2. Per Interface
An entry with a ccacUsConfigIfIndex with an
ifType of 'docsCableMaclayer' identifies an interface
policy.
Interface level thresholds supersedes global level
thresholds.
3. Per Upstream Channel
An entry with a ccacUsConfigIfIndex with an ifType of
'docsCableUpstream' identifies an upstream channel
policy.
Upstream level thresholds supersedes both global and
interface level thresholds.
