Tsunami MP-8100 Installation and Management Guide 72
• Priority per rule which defines the order of execution of PIRs during packet identification process. The PIR priority is a
number in the range 0-63, with priority 63 being executed first, and priority 0 being executed last. The PIR priority is
defined within a QoS class and can be different for the same PIR in some other QoS class. If all PIRs within one QoS
class have the same priority, the order of execution of PIR rules will be defined by the order of definition of SFCs, and
by the order of definition of PIRs in each SFC, within that QoS class.
A good example of this hierarchy is provided by the five predefined QoS classes:
1. Unlimited Best Effort
a. SF class: UL-Unlimited BE
– PIR: All; PIR Priority: 0
b. SF class: DL-Unlimited BE
– PIR: All; PIR Priority: 0
2. L2 Broadcast Best Effort
a. SF class: DL-L2 Broadcast BE
– PIR: L2 Broadcast; PIR Priority: 0
3. G711 VoIP
a. SF class: UL-G711 20 ms VoIP rtPS
– PIR: Vonage VoIP UL; PIR Priority: 1
– PIR: Cisco VoIP UL; PIR Priority: 1
b. SF class: DL-G711 20 ms VoIP rtPS
– PIR: Vonage VoIP DL; PIR Priority: 1
– PIR: Cisco VoIP DL; PIR Priority: 1
4. G729 VoIP
a. SF class: UL-G729 20 ms VoIP rtPS
– PIR: Vonage VoIP UL; PIR Priority: 1
– PIR: Cisco VoIP UL; PIR Priority: 1
b. SF class: DL-G729 20 ms VoIP rtPS
– PIR: Vonage VoIP DL; PIR Priority: 1
– PIR: Cisco VoIP DL; PIR Priority: 1
5. 2Mbps Video
a. SF class: DL-2Mbps Video
– PIR: Streaming Video (IP/TV); PIR Priority: 1
4.6.2 QoS Configuration
There are several pre-defined QoS classes, SFCs, and PIRs available that cover the most common types of traffic. If you want
to configure something else, build the hierarchy of a QoS class as follows:
1. Define PIR MAC Address, IP Address and TCP/UDP Port Entries.
2. Define PIRs and specify packet clarification rules, associate MAC Address/IP Address/TCP-UDP Port Entries if required.
3. Define SFCs
4. Define QoS Class by associating PIRs with relevant SFC.
5. Assign priorities to each PIR within each SFC.
For instructions on configuring a management station (a single station used for managing an entire network), see QoS
Configuration for a Management Station.
