Basic Configurations
Allocation of QoS Resources for a SAP Ingress Policy
The user is allowed to configure the number of classification entries the SAP requires (for
example: TQ).
Number of meters allocated automatically by system = TQ / 2 (up to a maximum of 32
meters).
To calculate the number of SAPs allowed, assume all configured to use 'TQ' QoS resources per
SAP.
Number of SAPs allowed = maximum classification entries / TQ.
Note: If the number of SAPs is greater than the system limit, then the system limit takes precedence.
The user is allowed to mix and match SAPs with different QoS resources (that is, using different
values of TQ). The allowed values for the parameter

18.
The following determines the number of QoS resources to be allocated for an SAP:
•
•
Only those FCs that are in use by the match-criteria classification entries are considered for the
number of FCs. Therefore, these FCs are referred to as 'FC in use'.
Given the number of traffic types to use per 'FC in use', the following rules apply for a SAP in a
VPLS service to arrive at number of classification entries per FC in use:

is configured with a value of 16, the system internally uses a value of
num-qos-resources
Number of match-criteria entries used to identify the FC.
Number of FCs to use and number of traffic-types to be policed per FC.
If a FC is in use and is created without explicit meters, use default meter #1 for unicast
traffic and default meter #11 for all other traffic types (that is, broadcast, multicast and
unknown-unicast). This requires two classification entries in hardware.
If a FC is in use and is created with an explicit unicast meter, use that meter for unicast
traffic and use default meter #11 for all other traffic types. This requires two classification
entries in hardware.
If a FC is in use and is created with an explicit unicast meter and explicit broadcast meter,
use these meters for unicast and broadcast traffic respectively and use meter #11 for all
other traffic types. This requires three classification entries in hardware.
If a FC is in use and is created with an explicit unicast meter and explicit multicast meter,
use the unicast meter for unicast traffic and multicast meter for all other kinds of traffic.
This requires two classification entries in hardware.
