These above configuration examples might be omitted or changed, but the remaining examples in this section
presume the above configurations.
Example: SGAC for Downstream Traffic
This example presumes that you have configured the rules according to the commands illustrated at the start
of this section.
•
All the voice flows in bucket 1.
•
All the CIR data flows are categorized in bucket 8.
The below example illustrates a sample configuration for SGAC with downstream traffic. In this example, if
voice traffic exceeds 30% bandwidth consumption, additional voice flows are denied.
•
30% downstream throughput is reserved exclusively for voice traffic.
The following command implements this configuration:
Router(config-fiber-node)#admission-control application-type 1 ds-bandwidth 30
The below example illustrates how flexible bandwidth allocation is configured. In this example, normal voice
traffic (application-type 1) is associated with two thresholds. Normal voice traffic alone can use up to 40%
of the service group's capacity, while normal and emergency voice traffic combined can use up to 50% of the
service group’s capacity. This means that emergency voice traffic can have at least 10% of the service group's
capacity, even if normal voice traffic has used up its share of 40%:
Router(config-fiber-node)#admission-control application-type 1 ds-bandwidth 40
Router(config-fiber-node)#admission-control application-type 1-2 ds-bandwidth 50
where,
•
1 is normal voice application type
•
2 is emergency voice application type
